Proximal tibiofibular joint (PTFJ) instability is a rare knee injury, accounting for less than 1% of knee injuries. Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. eCollection 2023 Jan. Mediterr J Rheumatol. The most (77% to 90%) PTFJ dislocations and instability were anterolateral/unspecified anterior dislocation or instability. 1998 Feb;84(1):84-7. Instability of the joint can be a result of an injury to these ligaments. Instability of the proximal tibiofibular joint - PubMed Am J Sports Med. Zhongguo Gu Shang. Atraumatic instability is more common and often misdiagnosed. Proximal Tibiofibular Joint Arthritis Co-existing With a Medial Meniscal Tear: A Case Report. Proximal tibiofibular stabilization by anatomical ligamentoplasty and Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. 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. Medial Patellar Instability: A Systematic Review of the Literature of Outcomes After Surgical Treatment. Methods: 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). Are you experiencing proximal tibiofibular joint instability? The common peroneal nerve (CPN) is visualized and protected throughout the case.

A prospective study of normal knees and knees with surgically verified grade III injuries. The condition is often missed, and the true incidence is unknown. Traumatic dislocations of the proximal tibiofibular joint are uncommon and are normally caused by high-energy injury or a fall on a twisted knee. Surgical Management of Proximal Tibiofibular Joint Instability Using an Adjustable Loop, Cortical Fixation Device. Clinical Characteristics and Outcomes After Anatomic Reconstruction of the Proximal Tibiofibular Joint. Axial fat-suppressed proton density weighted image at the PTFJ demonstrates marked soft tissue edema surrounding the joint with intact anterior (green arrow) and posterior (blue arrow) PTFJ ligaments. Disclaimer. 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. Epub 2022 Apr 1. 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. When the knee is flexed beyond 30 degrees, relaxation of the FCL and biceps femoris tendons allows the fibula to shift anteriorly which reduces joint stability and allows the fibular head to move approximately 7-10 mm in the anteroposterior plane.6,7 In the event of an added twisting element, external rotation of the tibia pulls the fibula laterally and tension in the anterolateral compartment musculature then further draws the fibula anteriorly.8. Proximal tibiofibular joint instability is a very unusual and uncommon condition. In order to best treat this pathology, Dr. LaPrade and his team have developed an anatomic proximal posterior tibiofibular joint reconstruction procedure. 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. Proximal tibiofibular joint instability is a very unusual and uncommon condition. Accessibility Optimal radiographic evaluation of the PTFJ is performed in 45-60 degrees internal rotation. This helps us to confirm that the patient does have instability of the proximal tibiofibular joint which may require surgery. Rule out lateral meniscus tear. Careers. PMID: 20127312. In the past, chronic instability was treated with arthrodesis or fibular head resection; however, complications related to altered knee and ankle biomechanics rendered these options less desirable.13,14,15, As knee ligament reconstruction surgery has developed, various techniques to reconstruct the ligaments have been described. The proximal tibiofibular joint (PTJF) can be injured with the structures in the lateral aspect of the knee in a multi-ligament knee injury (MLKI) patient. Suspicion of atraumatic injury to the proximal tibiofibular joint warrants extensive inspection during the physical examination of the knee. 1997 Jul-Aug;25(4):439-43. doi: 10.1177/036354659702500404. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. An anatomic study. Level of evidence: 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. While it is often difficult to identify a complete tear, in the absence of a history of dislocation or instability, edema in the ligaments associated with a fibular bone bruise along the posterior ligament attachment should raise awareness of recent traumatic injury. Just below these structures, the posterior proximal tibiofibular ligament is inspected. In other circumstances, significant trauma or a motor vehicle accident can cause a disruption of the proximal tibiofibular joint. Chronic instability is commonly the result of untreated or misdiagnosed subluxation of the PTFJ. Imaging Techniques Inclusion criteria were as follows: PTFJ instability treatment techniques, PTFJ surgical outcomes, English language, and human studies. Both the anterior and posterior ligaments may be torn however the posterior ligament is weaker and more often torn (Figures 6-8). Instability of the proximal tibiofibular joint occurs when the ligaments which provide stability to this joint are injured. On the lateral radiograph the fibular head barely intersects the radio-dense line (dotted line) representing the posteromedial margin of the lateral tibial condyle. 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. Conclusion: The ligaments of the human proximal tibiofibular joint were able to withstand a mean ultimate failure load of 517 144 N for the anterior complex and 322 160 N for the posterior complex. 1991 Nov;20(11):957-60. [Chronic instability of the proximal tibio-fibular articulation: hemi-long biceps ligamentoplasty by the Weinert and Giachino technique. A chronically injured CPN may appear atrophic with abnormally increased T2 signal as well as an abnormal contour due to surrounding scar tissue which often effaces the normal perineural fat. 2022;8:8. doi: 10.1051/sicotj/2022008. Federal government websites often end in .gov or .mil. Dislocation of the proximal tibiofibular joint is a very uncommon condition that is easily misdiagnosed without clinical suspicion of the injury. The drill is advanced through all 4 cortices. Dr LaPrade performed a deep root repair to my meniscus, which saved me from a knee replacement at this time. Dr. La Prade had just moved to Vail and I was his 2nd patient @ The Steadman Clinic. 2019.
