PMID: 28326444. The integrity of the ankle and functional status of the peroneal nerve should also be assessed during the physical examination, because of the association of nerve, syndesmotic ligament, and interosseous membrane damage with this injury. The proximal (or superior) tibiofibular joint is a synovial joint between the superior aspects of the tibia and fibula and is one of the multiple sites of cartilaginous and fibrous articulation carrying the name of the tibiofibular joint. The first step in the management of chronic instability of the PTFJ is usually . Epub 2017 Mar 21. NCI CPTC Antibody Characterization Program. History of Atraumatic Injury Pessoa P, Alves-da-Silva T, Guerra-Pinto F. Knee Surg Sports Traumatol Arthrosc. There are no specific exercises for proximal tibiofibular joint instability. Proximal Tibiofibular Joint Arthritis Co-existing With a Medial Meniscal Tear: A Case Report. The PTFJ is also unstable on physical examination. More commonly, however, AP and lateral radiographs are performed (Figure 4). MRIs ability to directly inspect the PTFJ supporting ligaments and relevant adjacent anatomy allows accurate characterization of the often unexpected injuries to the PTFJ. This is because there are no muscles that can control the joint for most activities of daily living. The condition is often missed, and the true incidence is unknown. Anterolateral dislocation commonly stems from injury to the anterior and posterior capsular ligaments, and commonly the lateral collateral ligament.1,2 The common cause of traumatic anterolateral dislocation is a fall on a flexed knee, or a violent twisting motion during an athletic activity.3 The hyperflexed knee results in relaxation of the biceps femoris tendon and the lateral collateral ligament, and the violent twisting of the body creates a torque that pushes the fibular head laterally to the edge of the lateral tibial metaphysis.1,2 The forced plantar flexion and ankle inversion forces the laterally displaced fibular head anteriorly.1, The early recognition of instability in the proximal tibiofibular joint is necessary to optimize management of the injury and to avoid potential misdiagnosis. 1991 Nov;20(11):957-60.

With the knee flexed 90 the fibular head may be subluxed/dislocated by gentle pressure in an anterior or posterior direction. Kobbe P., Flohe S., Wellmann M., Russe K. Stabilization of chronic proximal tibiofibular joint instability with a semitendinosus graft. AJR Am J Roentgenol. R. F. (2010). 1978 Jul;131(1):133-8. doi: 10.2214/ajr.131.1.133. It can be associated with subtle instability and subluxation or frank dislocation of both the PTFJ and the native knee joint. In the past, while others have often treated this instability of this joint by fusing it, we have reported through research that a proximal posterior tibiofibular joint ligament reconstruction is easily performed, does not overconstrain the joint and has decreased the chance of leading to ankle pathology further down the line. Reconstruction for recurrent dislocation of the proximal tibiofibular joint. A fat-suppressed proton density-weighted axial image (12B) demonstrates post-surgical appearance after open PTFJ ligament reconstruction with hamstring autograft (arrows) in a 30 year-old competitive weightlifter with chronic PTFJ instability. All nonsurgical therapies should be attempted before surgical intervention. On the axial, sagittal, and coronal images, the anterior tibiofibular ligament (green arrows) is diffusely edematous and a portion of the ligament fibers are discontinuous. In general, reaming a tunnel from front to back (anterior to posterior) through the fibular head and having it exit where the proximal tibiofibular joint posterior ligaments attach, and then drilling another tunnel from front to back on the tibia and which exits posteriorly at the attachment site of the proximal posterior tibiofibular joint ligaments, is the desired location for an anatomic-based reconstruction graft. Flexing the knee to 90 degrees to relax the lateral collateral ligament and biceps femoris tendon, then moving the fibular head anteriorly and posteriorly, can test instability of the joint. Soft tissue edema is present in the anterior (green arrow) and posterior (blue arrows) PTFJ ligaments. While protecting the CPN, sharp dissection to the fibular head is performed. The surgical treatment for proximal tibiofibular joint instability most often consists of an anatomic reconstruction of the torn ligaments. Recent traumatic anterolateral proximal tibiofibular joint dislocation. The integrity of the proximal tibiofibular joint is best visualized through plain radiographs. We recommend joint reconstruction to repair the proximal tibiofibular joint, which will retain the functional anatomy and rotation of the joint, over arthrodesis, especially in children and athletes. In fact 2 years ago I finished climbing the top 100 peaks in CO. 2023 Lineage Medical, Inc. All rights reserved, Knee & Sports | Proximal Tib-Fib Dislocation. In acute cases, we have found that immobilization in a brace in full extension for 3 weeks is often very effective to allow the posterior proximal tibiofibular joint ligament tear to scar in sufficiently such that there is no instability. (Please keep reading below for more information on this condition.). Imaging of Proximal Tibiofibular Joint Instability: A 10 year retrospective case series. Epub 2005 Dec 22. Stop Searching under the Streetlight! It is common for patients to also have transient peroneal nerve injuries, especially with posteromedial dislocation.1,2 Tightening is gradually tested by manipulation of the proximal fibula, until appropriate stability is achieved. Clinical Characteristics and Outcomes After Anatomic Reconstruction of the Proximal Tibiofibular Joint. The tibiofibular joints are a set of articulations that unite the tibia and fibula. PMID: 16374587. The anterior ligament is composed of three to four bundles and is further reinforced by the anterior aponeurosis arising from the long head of the biceps femoris tendon (BFT).3,4 The posterior ligament is generally composed of three bundles and significantly weaker than the anterior ligament (Figure 3).5 The inherent joint stability is also directly related to the inclination of the articular-surface which is classically defined as horizontal or oblique. Protection of the peroneal nerve during surgery helps to prevent injury and relieves symptoms common to this injury. government site. Reconstructive procedures are recommended for patients whose source of pain is instability in the joint as opposed to arthritis. On the AP radiographs the right knee demonstrates decreased overlap between the fibular head and the lateral tibial condyle compared with the left indicating that the fibular head is displaced laterally. Sequential axial (1A), coronal (1B), and sagittal (1C) fat-suppressed proton density-weighted images are provided through the proximal tibiofibular joint. Atraumatic instability is more common and often misdiagnosed. Proximal tibiofibular (PTF) joint instability is a rare condition: only 96 cases have been reported in the published literature. official website and that any information you provide is encrypted PMID: 1749660. Plain radiographs should be taken from anteroposterior, lateral, and oblique (45 to 60 degrees internal rotation of the knee) views, with comparison views from the contralateral knee, or from the preinjury knee if possible.5 When a diagnosis is suspected but not clearly established by plain radiographs, axial computed tomography has been found to be the most accurate imaging modality for detection of injury of the proximal tibiofibular joint.6 Magnetic resonance imaging (MRI) can also confirm a diagnosis of recent dislocation, based on the presence of pericapsular edema of the joint and edema of the soleus at its fibular origin of the popliteus muscle, but this finding is often absent in chronic and atraumatic cases.7, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), on Management of Proximal Tibiofibular Instability. Journal of the American Academy of Orthopaedic Surgeons &NA; Injury to the proximal tibiofibular joint is typically seen in athletes whose sports require violent twisting motions of the flexed knee. 2000 Mar-Apr;28(2):191-9. doi: 10.1177/03635465000280020901. The posterior ligament is disrupted near the fibular attachment on the axial image with subtle irregularity on the sagittal image. Dr LaPrade performed a deep root repair to my meniscus, which saved me from a knee replacement at this time. A variety of surgical treatments have been proposed over the last decades. In the setting of acute injury and subsequent stabilization, the posterior PTFJ ligaments have been shown to scar, thereby precluding the need for a full reconstruction.22 Moreover, the avulsion fracture portends bone-to-bone healing and any reconstruction technique requiring drilling through the posteromedial aspect of the fibular head risks comminuting and further displacing the fracture fragment. Imaging Techniques Ogden 10 reported that 57% of patients with acute proximal tibiofibular dislocations required surgery for ongoing symptoms after treatment failure with closed reduction and 3 weeks of immobilization. Successful diagnosis of the injury can be improved by a better understanding of the biomechanics of the joint and a clinical suspicion of the injury when symptoms are present. Instability of the proximal tibiofibular joint (PTFJ) may be acute or chronic in etiology and four types of instability initially described by Ogden include anterolateral dislocation, posteromedial dislocation, superior dislocation, and atraumatic subluxation.1Anterolateral dislocation is by far the most common form of instability and the focus of this discussion. [Chronic instability of the proximal tibio-fibular articulation: hemi-long biceps ligamentoplasty by the Weinert and Giachino technique. (For a review of the posterolateral corner, please refer to https://radsource.us/posterolateral-corner-injury). Reconstructive procedures are recommended for patients whose source of pain is instability in the joint as opposed to arthritis. The integrity of the proximal tibiofibular joint is best visualized through plain radiographs. Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. The implant is pulled through, flipping the medial button on the outside of the anteromedial cortex. 31 year-old female status-post fall and twisting injury while skiing with lateral knee pain radiating down the calf. During significant trauma, traumatic dislocations of the tibiofibular joint are commonly missed, so the physical examination of this joint is a significant part of the comprehensive knee examination. Warner B.T., Moulton S.G., Cram T.R., LaPrade R.F. Published by Elsevier Inc. All rights reserved. Clinical and Surgical Pearls In some cases, the posterior ligament will be notably absent, but given how small the ligaments are, chronic disruption and subsequent scarring may mask the underlying pathology and therefore isolated asymmetric osteoarthritis of the PTFJ may be the only clue.12. Although many patients do not note symptoms during daily activities, symptoms may develop during activities that require sudden changes in direction. Improved outcomes after all forms of PTFJ instability treatment were reported; however, high complication rates were associated with both PTFJ fixation (28%) and fibular head resection (20%). The treatment of proximal tibiofibular joint instability depends upon the time of presentation. A systematic review was performed according to Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Gross anatomy Articulation fibula: flat facet of the fibular head Knee Surg Sports Traumatol Arthrosc. Rule out lateral meniscus tear. 1997 Jul-Aug;25(4):439-43. doi: 10.1177/036354659702500404. Klaunick G. Recurrent idiopathic anterolateral dislocation of the proximal tibiofibular joint: case report and literature review. Anatomic reconstruction of chronic symptomatic anterolateral proximal tibiofibular joint instability. Optimal radiographic evaluation of the PTFJ is performed in 45-60 degrees internal rotation. Knee Surg Sports Traumatol Arthrosc. Methods such as arthrodesis and fibular head resection have largely been replaced with various . Orthop Rev. 48 year-old female with an acute PLC sprain and ACL tear. This site needs JavaScript to work properly. Most commonly, hamstring allografts and autografts are used to reconstruct the proximal tibiofibular joint anatomically. Chronic instability is commonly the result of untreated or misdiagnosed subluxation of the PTFJ. Related While the role of the fibula and the posterolateral corner (PLC) in maintaining knee stability has received widespread attention, the contribution of the proximal tibiofibular joint to knee stability is often overlooked and injuries may easily go unnoticed. Sep 11, 2016 | Posted by admin in SPORT MEDICINE | Comments Off on Management of Proximal Tibiofibular Instability. 2010 Nov;18(11):1452-5. doi: 10.1007/s00167-010-1049-9. Improved outcomes can be expected after surgical treatment of PTFJ instability. Treatment for proximal tibiofibular joint stability requires that nonsurgical management be attempted first for patients with atraumatic subluxation of the proximal tibiofibular joint. 4010 W. 65th St. Accessibility Traumatic dislocations commonly cause pain along the lateral knee that radiates into the region of the iliotibial band and the patellofemoral joint and is increased with palpation of the prominent fibular head and ankle motion.4 The patients pain commonly limits the range of motion, especially knee extension, and motion of the ankle; the patients ability to bear weight on the affected leg is also limited by pain. Halbrecht JL, Jackson DW. This results in the fibula rotating away from the tibia during deep squatting. The site is secure. The proximal tibiofibular joint ligaments both strengthen the joint and allow it to rotate and translate during ankle and knee motion. Traumatic dislocations of the proximal tibiofibular joint are uncommon and are normally caused by high-energy injury or a fall on a twisted knee. Abstract Dislocation of the tibiofibular joint is rare and usually results from a traumatic event. Particular attention is paid to the status of the menisci, patellofemoral tracking, cruciate ligaments, and presence of loose bodies as pathologies in these areas can mimic . Nonoperative treatment is associated with persistent symptoms, whereas both fixation and fibular head resection are associated with high complication rates. Fibular resection during an arthrodesis procedure can decrease ankle pain and instability after surgery. 2018 Apr;26(4):1104-1109. doi: 10.1007/s00167-017-4511-0. Most patient histories do not reveal any mechanism of injury to the proximal tibiofibular joint, and symptoms of lateral knee pain can be very misleading. (including injections and arthroscopic surgery), I heard Dr. La Prade was going to practice in the Twin Cities - where I live, & waited for him, based on his renown reputation. In acute cases, it may be difficult to make the patient relax sufficiently to be able to examine for proximal tibiofibular joint instability, but usually having the knee flexed to 90 degrees and trying to perform an anterolateral subluxation maneuver of the proximal tibiofibular joint is sufficient to confirm this diagnosis. Epub 2018 Jul 23. During significant trauma, traumatic dislocations of the tibiofibular joint are commonly missed, so the physical examination of this joint is a significant part of the comprehensive knee examination. PMID: 4837931. Epub 2017 Mar 20. Hey - if he is good enough for Olympic and professional athletes..he's good enough for me! 2022 Jun 11;14(6):e25849. Resecting and protecting the peroneal nerve during surgery can prevent peroneal nerve palsy. Acute injury to the common peroneal nerve (CPN) may manifest as nerve thickening and increased T2 signal consistent with edema and swelling. PMID: 29881700; PMCID: PMC5989917. Common considerations include lateral meniscus pathology, FCL injury/PLC instability, biceps tendonitis, and distal iliotibial band friction syndrome. Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. The clinical presentation of joint injury can range from common idiopathic subluxation with no history of trauma, to less common high-energy traumatic dislocations that may be associated with long bone fracture. I can run, bike, & climb mountains. Arthroscopy. The systematic review identified 44 studies (96 patients) after inclusion and exclusion criteria application. I was told by one of the orthopedic surgeons that I worked with that I would never run again and would be lucky if I could ever hike again. Level IV, systematic review of level IV studies. Proximal tibiofibular joint instability is a very unusual and uncommon condition. Atraumatic subluxation is thought to result from injury to the anterior ligament and to the anterior capsule of the joint, and it can be associated with Ehlers-Danlos syndrome, muscular dystrophy, and generalized laxity.1 Subluxation typically occurs in patients who have no history of inciting trauma but may have generalized ligamentous laxity; the condition is not commonly bilateral. Proximal Tibiofibular Joint (PTFJ):Stabilizing Tape Technique for Posterior Instability Learn How We Can Help You Stay Active Request a Consultation About the Author: Robert LaPrade, MD Robert LaPrade, MD, PhD has specialized skills and expertise in diagnosing and treating complicated knee injuries. Proximal tibiofibular joint (PTFJ) instability is a rare knee injury, accounting for less than 1% of knee injuries. Epub 2017 May 10. Many common injuries can cause the same symptoms as proximal tibiofibular dislocation; therefore the integrity of the surrounding ligamentous structures should be investigated before a diagnosis is made. Preoperative Considerations Dekker TJ, DePhillipo NN, Kennedy MI, Aman ZS, Schairer WW, LaPrade RF. Instability of the proximal tibiofibular joint (PTFJ) can present as frank dislocations, subtle symptoms of lateral knee pain, discomfort during activity, or symptoms related to irritation of the common peroneal nerve. 2020 Jun;36(6):1649-1654. doi: 10.1016/j.arthro.2020.01.056. doi: 10.2214/AJR.07.3406. Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. It causes significant lateral sided knee pain and functional deficits and can be associated with up to 9% of multiligament knee injuries. The posterior capsule is identified with the insertion of the biceps femoris tendon (BFT) and the FCL. Traumatic dislocations of the proximal tibiofibular joint are uncommon and are normally caused by high-energy injury or a fall on a twisted knee. In cases where the symptoms of proximal tibiofibular joint instability are difficult to discern, especially for chronic cases, we have found that taping of the proximal tibiofibular joint is helpful to confirm the diagnosis. If one has a chronic proximal tibiofibular joint injury, we prefer to trial taping to validate that the symptoms of the proximal tibiofibular joint injury are improved with the taping program. Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. Ogden JA. The early recognition of instability in the proximal tibiofibular joint is necessary to optimize management of the injury and to avoid potential misdiagnosis. doi: 10.7759/cureus.25849. and transmitted securely. Unauthorized use of these marks is strictly prohibited. When fractures are present, they are more often associated with the posterior ligament and it is important to distinguish these fractures from a posterolateral corner injury. Request Case Review or Office Consultation. Clin Orthop Relat Res. Joint subluxation is common in adolescents, typically girls, and results from hypermobility of the joint, in which symptoms can decrease with skeletal maturity.2 Some studies have shown that congenital dislocation of the knee can also be associated with atraumatic superior dislocation of the proximal tibiofibular joint.1, Traumatic dislocations of the proximal tibiofibular joint are uncommon and are normally caused by high-energy injury or a fall on a twisted knee. We advise that patients initiate a program of weaning off the crutches at the six week point and starting the use of a stationary bike to regain the strength of their quadriceps mechanism. PMID: 32061975. 2014 Sep;472(9):2691-7. doi: 10.1007/s11999-014-3574-1. You can schedule an office consultation with Dr. LaPrade. The Proximal Tibiofibular Joint: A Biomechanical Analysis of the Anterior and Posterior Ligamentous Complexes. In more chronic cases, we have the patient squat down, which can often demonstrate that the proximal tibiofibular joint is being subluxed. The reconstructive procedure is recommended for patients whose pain is a result of joint instability. Shapiro G.S., Fanton G.S., Dillingham M.F. The anterior ligament should be identified in all three planes. Dr. Robert F. LaPrade operated on my right knee in May of 2010. Treatment of Instability of the Proximal Tibiofibular Joint by Dynamic Internal Fixation With a Suture Button. Espregueira-Mendes JD, da Silva MV. However, on a true lateral radiograph, the fibular head should intersect a line created by the posteromedial portion of the lateral tibial condyle and anterior or posterior displacement of the fibular head will disrupt this relationship.9 In cases of transient traumatic dislocation, anatomic alignment may be within normal limits and therefore normal radiographic alignment does not exclude the possibility of recent dislocation or instability. FOIA In acute cases, we have found that immobilization in a brace in full extension for 3 weeks is often very effective to allow the posterior proximal tibiofibular joint ligament tear to scar in sufficiently such that there is no instability. Anatomy of the proximal tibiofibular joint. 1 The TFJ is stabilized by 3 broad ligaments forming a fibrous capsule, 3 2 posterior proximal tibiofibular ligament and 1 stronger anterior tibiofibular ligament. Proximal tibiofibular ligament reconstruction, specifically biceps rerouting and anatomic graft reconstruction, leads to improved outcomes with low complication rates. 3. In acute anterolateral PTFJ dislocation without spontaneous dislocation or fracture, closed reduction is performed. There are two ways to initiate a consultation with Dr. LaPrade: You can providecurrentX-rays and/or MRIs for a clinical case review with Dr. LaPrade. Clin Orthop Relat Res. Careers. Patients who undergo this reconstruction are kept on crutches for 6 weeks with no to minimal weight-bearing movement, but are allowed full range of motion. Apropos of 3 cases]. Only gold members can continue reading. Atraumatic instability is more common and often misdiagnosed. Limit patients to passive flexion until 6 weeks to reduce the stress that is applied to the reconstructed ligaments (prevent biceps femoris from pulling on the fibular head). This helps us to confirm that the patient does have instability of the proximal tibiofibular joint which may require surgery.
