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. PMID: 28326444. Bookshelf 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. Proximal Tibiofibular Joint Arthritis Co-existing With a Medial Meniscal Tear: A Case Report. Before Recent traumatic anterolateral proximal tibiofibular joint dislocation. As the anterior arm of the long head of the biceps femoris tendon courses inferiorly, it contributes to the anterior aponeurosis and is intimately associated with the anterior tibiofibular ligament (green arrows). PMID: 32061975. 3D renders demonstrate the anterior proximal tibiofibular (ATFL) and posterior proximal tibiofibular (PTFL) ligaments and adjacent anatomy, including the fibular collateral ligament (FCL), biceps tendon (BFT), anterior arm of the biceps tendon (ABT), the popliteofibular ligament (PFL) and the inferior proximal tibiofibular ligament (ITFL). History and physical examination are very important for diagnosis. Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. Effects of a Partial Meniscectomy on Articular Cartilage, Femoral Condyle | Articular Cartilage Injury, FCL Injury or Lateral Collateral Ligament LCL Tear, Lateral Patellar Instability | MPFL Repair, Instability of the joint, especially during deep squatting, Concurrent irritation of the common peroneal nerve, because the common peroneal nerve crosses the lateral aspect of the fibular neck within 2-3 cm of the lateral aspect of the fibular head. The fibular head lies in an angled groove behind the lateral tibial ridge, which helps to prevent anterior fibular movement with knee flexion [7]. official website and that any information you provide is encrypted The first step in the management of chronic instability of the PTFJ is usually . The anterior ligament should be identified in all three planes. Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. A systematic review was performed according to Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. The proximal tibiofibular joint should be palpated for tenderness, and laxity should be evaluated by translating the fibular head anteriorly and posteriorly with the thumb and index finger and asking the patient if the symptoms are reproduced or if there is any apprehension.4 The stability of the proximal tibiofibular joint is typically increased by full extension of the knee; if it is not, the lateral collateral ligament and posterolateral structures may also be injured. Dr. Robert F. LaPrade operated on my right knee in May of 2010. 2019. Orthop Rev. Epub 2016 Jan 16. 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. Careful dissection to the posterior aspect of the joint is carried out after a peroneal nerve neurolysis is performed. With acute injury, patients usually complain of pain and a prominence in the lateral aspect of the knee. Chapter Synopsis Suspicion of atraumatic injury to the proximal tibiofibular joint warrants extensive inspection during the physical examination of the knee. Fibular resection during an arthrodesis procedure can decrease ankle pain and instability after surgery. 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. Suspicion of atraumatic injury to the proximal tibiofibular joint warrants extensive inspection during the physical examination of the knee.

Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. 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. Clin Orthop Relat Res. 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. The arthrodesis procedure is recommended for patients in whom the correction of joint instability would not relieve pain, such as patients with proximal tibiofibular joint arthritis. A slightly curved lateral incision over the fibular head is made. 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. Improved outcomes can be expected after surgical treatment of PTFJ instability. The most common traumatic dislocations are in an anterolateral direction, followed by posteromedial and superior dislocations. Bilateral, atraumatic, proximal tibiofibular joint instability. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. Nonoperative treatment is associated with persistent symptoms, whereas both fixation and fibular head resection are associated with high complication rates. Proximal tibiofibular joint (PTFJ) instability is a rare knee injury, accounting for less than 1% of knee injuries. Dislocation of the proximal tibiofibular joint is a very uncommon condition that is easily misdiagnosed without clinical suspicion of the injury. 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. Concurrent surgical treatment of posterolateral corner (PLC) and PTFJ instability poses technical challenges due to the limited working space . Conclusions: Most commonly, hamstring allografts and autografts are used to reconstruct the proximal tibiofibular joint anatomically. Proximal tibiofibular ligament reconstruction, specifically biceps rerouting and anatomic graft reconstruction, leads to improved outcomes with low complication rates. All other clinical possibilities should be ruled out before a diagnosis is made. Exclusion criteria were cadaveric studies, animal studies, basic science articles, editorial articles, review articles, and surveys. Imaging Techniques Comparison with the contralateral knee is useful to determine adequate tightness. The anterior-most sagittal image demonstrates the relationship between the anterior arm of the short head of the biceps femoris tendon (purple arrow), the fibular insertion of the FCL (yellow arrow), and the anterior tibiofibular ligament (green arrow). An official website of the United States government. 27 The proximal tibiofibular joint is a synovial membrane-lined, hyaline cartilage articulation that communicates with the knee joint in However, in chronic cases, immobilization would not be sufficient to achieve this goal. Anatomic reconstruction of chronic symptomatic anterolateral proximal tibiofibular joint instability. Patients often report symptoms such as knee instability and giving way during these activities, as well as clicking and popping during daily activities.3 The anatomy and function of the proximal tibiofibular joint. Most proximal tibiofibular joint instabilities can be treated with closed reduction and conservative care, but some require internal fixation or soft-tissue reconstruction. Log In or Register to continue 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. LaPrade RF, Gilbert TJ, Bollom TS, Wentorf F, Chaljub G. The magnetic resonance imaging appearance of individual structures of the posterolateral knee. Sequential axial (9A) and coronal (9B) fat-suppressed proton density-weighted images demonstrate a 20 mm avulsion fracture of the fibular head (red arrows) medial to the styloid at the posterior tibiofibular ligament insertion (blue arrows). 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. Proximal tibiofibular joint instability is a very unusual and uncommon condition. Proximal tibiofibular joint (PTFJ) instability can be easily missed or confused for other, more common lateral knee pathologies such as meniscal tears, fibular collateral ligament injury, biceps femoris pathology, or iliotibial band syndrome. 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. Inclusion criteria were as follows: PTFJ instability treatment techniques, PTFJ surgical outcomes, English language, and human studies. Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. Methods: Typically, the proximal tibiofibular joint is injured in a fall when the ankle is plantar-flexed, with the stress being brought through the fibula, will cause the proximal fibula to sublux (partial dislocation) out of place over the lateral aspect of the knee joint. Diagnosis requires careful assessment of radiographs of the knee and tibia (often missed injury). Knee Surg Sports Traumatol Arthrosc. PMID: 20440223. Taping of the proximal tibiofibular joint, in a reverse direction to pull it away from the tendency to anterolateral subluxation, can be very effective at obtaining a validated clinical response in a patient who has injuries to this joint. Atraumatic instability is more common and often misdiagnosed. Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. Axial fat-suppressed proton density-weighted images demonstrates a poorly defined chronically torn posterior PTFJ ligament (blue arrowhead). 1997 Jul-Aug;25(4):439-43. doi: 10.1177/036354659702500404. 2017 Aug;33(8):1587-1593. doi: 10.1016/j.arthro.2017.03.012. CHRONIC INSTABILITY. The condition is often missed, and the true incidence is unknown. PMID: 97965. To provide the highest quality clinical and technology services to customers and patients, in the spirit of continuous improvement and innovation. I am 5-months post surgery, and am doing great, stationary biking and exercising every day, no pain.You know you are seeing the best when you find out he has written over 500 medical journal articles - among many other accomplishments. Warner B.T., Moulton S.G., Cram T.R., LaPrade R.F. 2017 Oct 25;30(10):972-975. doi: 10.3969/j.issn.1003-0034.2017.10.019. 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. In this regard, it is recommended that the strengths of grafts chosen for proximal tibiofibular reconstructions meet or exceed these values. Although many patients do not note symptoms during daily activities, symptoms may develop during activities that require sudden changes in direction. Pessoa P, Alves-da-Silva T, Guerra-Pinto F. Knee Surg Sports Traumatol Arthrosc. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. The integrity of the proximal tibiofibular joint is best visualized through plain radiographs. Proximal tibiofibular dislocation is commonly missed initially when high-energy trauma results in other traumatic fractures as well, such as injury to the tibial plateau or shaft, injury to the ipsilateral femoral head or shaft, ankle fracture, or knee dislocation. Resecting and protecting the peroneal nerve during surgery can prevent peroneal nerve palsy. Diagnosis requires careful assessment of radiographs of the knee and tibia (often missed injury). This is because there are no muscles that can control the joint for most activities of daily living. The proximal tibiofibular joint is a synovial joint that functions in dissipating lower leg torsional stresses and lateral tibial bending moments and in transmitting axial loads in weight-bearing [ 1 ]. 48 year-old female with an acute PLC sprain and ACL tear. All other clinical possibilities should be ruled out before a diagnosis is made. MRIs ability to directly inspect the PTFJ supporting ligaments and relevant adjacent anatomy allows accurate characterization of the often unexpected injuries to the PTFJ. 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. The TightRope is subsequently tightened by pulling and spreading the sutures until the lateral button reaches the fibular head. Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. This was devastating news after being a top triathlete (3rd in the world in my age group in 1989 & 1st nationally in my age group) and a big marathon runner. For the case discussed in Figure 9 above, stabilization with an adjustable loop cortical fixation device was selected for multiple reasons. The posterior capsule is identified with the insertion of the biceps femoris tendon (BFT) and the FCL. A proximal tib-fib dislocation is a disruption of the proximal tibia-fibula joint associated with high energy open fractures of the tibia and peroneal nerve injury. Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. 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. The proximal tibiofibular joint is located between the lateral tibial plateau of the tibia, and the head of the fibula. Am J Sports Med. 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. Anatomic reconstruction of chronic symptomatic anterolateral proximal tibiofibular joint instability. The CPN (red arrowhead) is abnormally flattened with increased T2 signal. For the treatment of PTFJ instability, there were 18 studies (35 patients) describing nonoperative management, 3 studies (4 patients) reported on open reduction, 11 studies (25 patients) reported on fixation, 4 studies (10 patients) that described proximal fibula resection, 3 studies (11 patients) reported on adjustable cortical button repair, 2 studies (3 patients) reported on ligament reconstructions, and 5 (8 patients) studies reported on biceps femoris tendon rerouting. Protection of the peroneal nerve during surgery helps to prevent injury and relieves symptoms common to this injury. Please enable it to take advantage of the complete set of features! The early recognition of instability in the proximal tibiofibular joint is necessary to optimize management of the injury and to avoid potential misdiagnosis. 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. Patients often report symptoms such as knee instability and giving way during these activities, as well as clicking and popping during daily activities.3, 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. With acute injury, patients usually complain of pain and a prominence in the lateral aspect of the knee. In order to ensure that the ligament heals without having it stretch out, it is recommended that the patients be non-weight or toe-touch weight bearing for the first six weeks to ensure that the joint is not overloaded to allow the reconstruction graft to start to heal in the tunnels. Reconstruction for recurrent dislocation of the proximal tibiofibular joint. Knee Surg Sports Traumatol Arthrosc. MRI evaluation of chronic instability is more challenging given the lack of associated soft tissue edema (Figure 11). Nate Kopydlowski and Jon K. Sekiya Clinical History: 21-year-old male with lateral knee pain radiating into the calf status-post soccer injury. Isolated traumatic instability of the proximal TFJ is an uncommon and underrecognized injury. Imaging of Proximal Tibiofibular Joint Instability: A 10 year retrospective case series. This results in the fibula rotating away from the tibia during deep squatting. Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. Report of two cases. eCollection 2023 Jan. Mediterr J Rheumatol. Management of Proximal Tibiofibular Instability Ogden JA. If one obtains the diagnosis soon after injury (acutely), immobilization of the knee in extension for a few weeks to try to get the posterior injured ligaments to heal is reasonable. However, I will always be thankful to Dr. Shirzad for at least examining my proximal tib-fib joint and his supportive chart note acknowledging the pain upon palpation. Level IV, systematic review of level IV studies. Instability of the joint can be a result of an injury to these ligaments. Just below these structures, the posterior proximal tibiofibular ligament is inspected. Instability of the proximal tibiofibular joint occurs when the ligaments which provide stability to this joint are injured. PMID: 1749660. McNamara WJ, Matson AP, Mickelson DT, Moorman CT 3rd. MRI evaluation of recent injury will often reveal soft tissue edema both anterior and posterior to the joint, as well as within the ligaments. . Patients with subluxation of the proximal tibiofibular joint commonly report pain over the joint that is aggravated by direct pressure over the fibular head. The diagnosis of joint instability can be confirmed by steroid and local anesthetic injection into the joint under fluoroscopic guidance, if pain is relieved. Clin Imaging. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. 3. J Pediatr Orthop B. Proximal Tibiofibular Joint Injuries - Discussion: - function of the PTFJ - accept 1/6 the axial load of the leg - resist torsional stresses originating from the ankle - resist tensile forces created with weight bearing - resists lateral bending forces - subluxation is common in preadolescent females and resolves with skeletal maturity Although many patients do not note symptoms during daily activities, symptoms may develop during activities that require sudden changes in direction. Tags: Surgical Techniques of the Shoulder Elbow and Knee in Sports Kerzner B, Mameri ES, Jackson GR, Casanova F, Boero I, Verdejo FG, Browning RB, Khan ZA, Dasari SP, Morgan VK, Chahla J. Arthrosc Tech. Thank you for choosing Dr. LaPrade as your healthcare provider. ABSTRACT 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. PMID: 28321475. In more chronic cases, we have the patient squat down, which can often demonstrate that the proximal tibiofibular joint is being subluxed.
