PMID: 27133689. According to the Ogden classification, proximal tibiofibular joint injuries can be classified into the following subgroups 1-6: type 1: subluxation (more often in children and adolescents ) type 2: anterior dislocation (most common ~85%) type 3: posteromedial dislocation type 4: superior dislocation Radiographic features Plain radiograph Because the joint is relatively inherently stable because of its bony anatomy when the knee is out straight, most cases of proximal tibiofibular joint instability occur when the knee is bent. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. The examination of patients with atraumatic subluxation or chronic instability should be performed with the knee flexed to 90 degrees. The tibiofibular joints are a set of articulations that unite the tibia and fibula. We anticipate that our patients will return back to full activities about 4-5 months after surgery, following the rehabilitation program. The implant is pulled through, flipping the medial button on the outside of the anteromedial cortex. To evaluate the treatment options, outcomes, and complications associated with proximal tibiofibular joint (PTFJ) instability, which will aim to improve surgical treatment of PTFJ instability and aid surgeons in their decision making and treatment selection. Pessoa P, Alves-da-Silva T, Guerra-Pinto F. Knee Surg Sports Traumatol Arthrosc. Review of Common Clinical Conditions of the Proximal Tibiofibular Joint MRIs ability to directly inspect the PTFJ supporting ligaments and relevant adjacent anatomy allows accurate characterization of the often unexpected injuries to the PTFJ. The coronal images demonstrate the normal anterior ligament located just caudal to the anterior arm of the short head of the biceps femoris tendon (purple arrow). The CPN (red arrowhead) is abnormally flattened with increased T2 signal. In general, we prefer an autograft (using ones own tissues) because it will heal in faster than an allograft (cadaver graft). Most commonly, hamstring allografts and autografts are used to reconstruct the proximal tibiofibular joint anatomically. Shapiro G.S., Fanton G.S., Dillingham M.F. Both the anterior and posterior ligaments may be torn however the posterior ligament is weaker and more often torn (Figures 6-8). . PMID: 28326444. April 25, 2013 - Appointment with Dr. Lyman, MD-Lyman Knee Clinic, Coeur D'Alene, ID. (Please keep reading below for more information on this condition.). The site is secure. I was hit by a car on my bicycle near Horsetooth Reservoir in CO. The drill is advanced through all 4 cortices. Epub 2017 Mar 24. With acute injury, patients usually complain of pain and a prominence in the lateral aspect of the knee. The integrity of the proximal tibiofibular joint is best visualized through plain radiographs. In most circumstances, it is the posterior proximal tibiofibular joint ligament that is injured. 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. 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. Proximal tibiofibular joint dislocation - Radiopaedia 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). official website and that any information you provide is encrypted A variety of surgical treatments have been proposed over the last decades. doi: 10.1016/j.eats.2017.09.003. Marchetti DC, Chahla J, Moatshe G, Slette EL, LaPrade RF. 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. Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. Rule out lateral meniscus tear. 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. The proximal tibiofibular joint (PTFJ) is the articulation of the lateral tibial plateau of the tibia and the head of the fibula. The most (77% to 90%) PTFJ dislocations and instability were anterolateral/unspecified anterior dislocation or instability. PMID: 97965. Proximal Tibiofibular Joint Instability - Radsource Robert LaPrade, MD, PhD Acute injury to the common peroneal nerve (CPN) may manifest as nerve thickening and increased T2 signal consistent with edema and swelling. Knee Surgery, Sports Traumatology, Arthroscopy, 18(11), 1452-1455 . Reconstructive procedures are recommended for patients whose source of pain is instability in the joint as opposed to arthritis. In fact 2 years ago I finished climbing the top 100 peaks in CO. Clinical Characteristics and Outcomes After Anatomic Reconstruction of the Proximal Tibiofibular Joint. To provide the highest quality clinical and technology services to customers and patients, in the spirit of continuous improvement and innovation. 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. Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. Resecting and protecting the peroneal nerve during surgery can prevent peroneal nerve palsy. The systematic review identified 44 studies (96 patients) after inclusion and exclusion criteria application. Nonoperative treatment is associated with persistent symptoms, whereas both fixation and fibular head resection are associated with high complication rates. It often appears striated due to the presence of multiple bundles, and it is located just caudal to the anterior arm of the short head of the biceps femoris tendon. Axial and coronal fat-suppressed proton density-weighted images demonstrate soft tissue edema surrounding the PTFJ with subtle irregularity of the posterior ligament (blue arrow) near the fibular attachment and an underlying bone contusion (arrowhead). 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 . Dirim B, Wangwinyuvirat M, Frank A, Cink V, Pretterklieber ML, Pastore D, Resnick D. Communication between the proximal tibiofibular joint and knee via the subpopliteal recess: MR arthrography with histologic correlation and stratigraphic dissection. Proximal Tibiofibular Joint Stabilization With Concurrent In this regard, it is recommended that the strengths of grafts chosen for proximal tibiofibular reconstructions meet or exceed these values. Please enable it to take advantage of the complete set of features! Atraumatic instability is more common and often misdiagnosed. The vast majority of the time, the torn ligaments are the posterior proximal tibiofibular joint ligaments, so a graft which is placed in the anatomic position to restore these ligaments has been proven to be successful. Methods such as arthrodesis and fibular head resection have largely been replaced with various . 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. Instability of the proximal tibiofibular joint (PTFJ) can be post-traumatic or due to accumulative injuries and may also be underdiagnosed pathology that can present with symptoms of lateral and/or medial knee pain. Surgical treatment discussion and videos courtesy of Jonathan A. Godin, MBA, MD, The Steadman Clinic and Steadman Philippon Research Institute. Because the posterior ligament is thinner it is often more difficult to identify and best evaluated on axial and sagittal images just anterior to the popliteus musculotendinous unit (Figure 5). 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 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. Epub 2022 Apr 1. 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. 2017 Oct 25;30(10):972-975. doi: 10.3969/j.issn.1003-0034.2017.10.019. The chief function of the proximal tibiofibular joint is to dissipate some of the forces on the lower leg such as torsional stresses on the ankle, lateral tibial bending movements, and tensile weight bearing. 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.
