Clinical and Surgical Pearls With acute injury, patients usually complain of pain and a prominence in the lateral aspect of the knee. Atraumatic instability is more common and often misdiagnosed. Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. 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. Clinically, PTJI can be seen in patients with no history of knee trauma (eg, idiopathic subluxation of the joint) and in patients experiencing high-energy traumatic dislocations that may be associated with long bone fractures. Four types of instability are distinguished: subluxation, anterolateral dislocation, posteromedial dislocation and superior dislocation. • Protection of the peroneal nerve during surgery helps to prevent injury and relieves symptoms common to this injury. L 166, 5th Main Service Road, Sector 6, HSR Layout, Outer Ring Road, Bengaluru 560102. Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. Fibular resection during an arthrodesis procedure can decrease ankle pain and instability after surgery. However, in chronic cases, immobilization would not be sufficient to achieve this goal. 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. Purpose: 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. Patients with subluxation of the proximal tibiofibular joint commonly report pain over the joint that is aggravated by direct pressure over the fibular head. Although many patients do not note symptoms during daily activities, symptoms may develop during activities that require sudden changes in direction. Imaging of Proximal Tibiofibular Joint Instability: A 10 year retrospective case series. Examination of the left proximal tib/fib articulation demonstrates evidence of marked increase mobility of the proximal fibula in relationship to the tibia. The examination of patients with atraumatic subluxation or chronic instability should be performed with the knee flexed to 90 degrees. Abstract: Injury to the proximal tibiofibular joint can lead to lateral knee pain and instability owing to chronic rupture of the posterior tibiofibular ligament. The proximal tibiofibular joint … 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. 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). may play a role in chronic ankle instability dysfunc-tion. After 6 weeks postoperatively, patients may start to use a stationary bike with low resistance. In patients who complain of pain and instability in the knee, the cause may sometimes be found in laxity of the proximal tibio-fibular joint. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. • Dislocation of the proximal tibiofibular joint is a very uncommon condition that is easily misdiagnosed without clinical suspicion of the injury. Preoperative Considerations Sep 11, 2016 | Posted by admin in SPORT MEDICINE | Comments Off on Management of Proximal Tibiofibular Instability. Protection of the peroneal nerve during surgery helps to prevent injury and relieves symptoms common to this injury. • Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. Nate Kopydlowski and Jon K. Sekiya A variety of surgical … The early recognition of instability in the proximal tibiofibular joint is necessary to optimize management of the injury and to avoid potential misdiagnosis. The condition is often missed, and the true incidence is unknown. Instability of the proximal tibio-fibular joint The proximal tibio-fibular joint consists of the articulating surfaces of the upper end of the fibular head and the lateral condyle of the tibia, which are covered with hyaline cartilage. Proximal tibiofibular joint instability (PTJI) is increasingly reported in the literature. Clinically, PTJI can be seen in patients with no history of knee trauma (eg, idiopathic subluxation of the joint) and in patients experiencing high-energy traumatic dislocations that may be associated with long bone fractures. 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. Clin Imaging. The diagnosis of proximal tibiofibular joint instability is almost always based on a thorough clinical exam. Proximal tibiofibular joint instability (PTJI) is increasingly re-ported in the literature. All Rights Reserved. An often overlooked contributor to Patients with subluxation of the proximal tibiofibular joint commonly report pain over the joint that is aggravated by direct pressure over the fibular head. This is an effective option for treating patients with dual pathology. 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. Parkes JC II, Zelko RR. Injury to the proximal tibiofibular joint can lead to lateral knee pain and instability owing to chronic rupture of the posterior tibiofibular ligament. We present a case of simultaneous total knee arthroplasty and proximal tibiofibular arthrodesis. 21,23,26 In contrast, clinical outcomes data after PTFJ ligament complex reconstruction have shown promising results, although there are … Initial management of traumatic joint dislocation should involve closed reduction under local anesthesia, followed by surgical intervention if reduction fails. • Dislocation of the proximal tibiofibular joint is a very uncommon condition that is easily misdiagnosed without clinical suspicion of the injury. Treatment for proximal tibiofibular joint stability requires that nonsurgical management be attempted first for patients with atraumatic subluxation of the proximal tibiofibular joint. Increased fibular external rotation will result in injury to the anterior capsule and ligaments of the proximal tibiofibular joint causing common complaints of "popping" and lateral knee pain. • Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. Nathan Kopydlowski, Eric Tannenbaum, Jon K. Sekiya Dislocation of the proximal tibiofibular joint is a very rare condition that is easily misdiagnosed without suspicion of the injury. J Bone Joint Surg Am. • All other clinical possibilities should be ruled out before a diagnosis is made. 2016;40(3):470-476. doi: 10.1016/j.clinimag.2015.12.011. 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. 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. • Fibular resection during an arthrodesis procedure can decrease ankle pain and instability after surgery. Although many patients do not note symptoms during daily activities, symptoms may develop during activities that require sudden changes in direction. The proximal tibiofibular joint ligaments both strengthen the joint and allow it to rotate and translate during ankle and knee motion. Because this joint is usually in the field of vi ew in radiography, CT, and MRI of the knee, eval-uation of it should be a part of all knee imaging assessments. - resist torsional stresses originating from the ankle. • All nonsurgical therapies should be attempted before surgical intervention. Injury to the proximal tibiofibular joint (PTFJ) is … All other clinical possibilities should be ruled out before a diagnosis is made. 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. Isolated and chronic anterolateral instability of the proximal tibiofibular joint (TFJ) is an uncommon condition, generally linked to an unrecognized or unhealed dislocation of the TFJ. The capsule is reinforced anteriorly and posteriorly by two ligaments. • Proximal tibiofibular joint instability is a very unusual and uncommon condition. We have found it to be very effective at restoring stability to this joint and not resulting in joint overconstraint. We anticipate that our patients will return back to full activities about 4-5 months after surgery, following the rehabilitation program. 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. Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. • The reconstructive procedure is recommended for patients whose pain is a result of joint instability. Conclusion: Proximal tibiofibular joint arthritis is uncommon and may be associated with tibiofemoral arthritis, proximal tibiofibular joint instability, and ankylosing spondylitis. Although the … 1 Anterolateral dislocation is by far the most common form of instability and the focus of this discussion. Resecting and protecting the peroneal nerve during surgery can prevent peroneal nerve palsy. Patients often report symptoms such as knee instability and giving way during these activities, as well as clicking and popping during daily activities.

The examination of patients with atraumatic subluxation or chronic instability should be performed with the knee flexed to 90 degrees. Case report. Keywords Proximal tibiofibular joint instability ! I am motivated to write as a sincere thank you and to give back to the internet world more information on the Proximal Tibiofibular Joint Instability. The most common traumatic dislocations are in an anterolateral direction, followed by posteromedial and superior dislocations. This is a real problem that can fall under the diagnostic radar or at least in my case with mainstream medical because it is not something that can always be directly seen on diagnostic tests. History of Atraumatic Injury 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. The treatment of proximal tibiofibular joint instability usually depends upon whether it is an acute or chronic injury. The most common traumatic dislocations are in an anterolateral direction, followed by posteromedial and superior dislocations. In 1974, Odgen described four forms of proximal tibiofibular instability, the most common of which was anterolateral dislocation caused by disruption of the proximal capsular ligaments [7, 8]. 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.1,2 Although many patients do not note symptoms during daily activities, symptoms may develop during activities that require sudden changes in direction. A variety of surgical treatments have been proposed over the last decades. Physical Examination Techniques Reconstructive procedures are recommended for patients whose source of pain is instability in the joint as opposed to arthritis. 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. 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. Rather it is a diagnosis of … Patients often report symptoms such as knee instability and giving way during these activities, as well as clicking and popping during daily activities.3 This results in the fibula rotating away from the tibia during deep squatting. 1973;55(1):177-183. 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. In chronic injuries, the instability … Copyright © 2021 IKOC. The proximal tibio-fibular joint consists of a joint cavity surrounded by a joint capsule (diarthrosis) forming a rather rigid joint. Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. 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. Radio- graphically the joint space is visible only in oblique projections. • Protection of the peroneal nerve during surgery helps to prevent injury and relieves symptoms common to this injury. 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 patient’s pain commonly limits the range of motion, especially knee extension, and motion of the ankle; the patient’s ability to bear weight on the affected leg is also limited by pain. Proximal tibiofibular joint instability is a very unusual and uncommon condition. - subluxation is common in preadolescent females and resolves with skeletal maturity.

Anterolateral dislocation commonly stems from injury to the anterior and posterior capsular ligaments, and commonly the lateral collateral ligament. The proximal tibiofibular joint ligaments both strengthen the joint and allow it to rotate and translate during ankle and knee motion. The integrity of the proximal tibiofibular joint is best visualized through plain radiographs. The examination of patients with atraumatic subluxation or chronic instability should be performed with the knee flexed to 90 degrees. Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. 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. Proximal tibiofibular subluxation is a rare condition. Imaging Techniques Background & Purpose: The knee is the most common site of injury in running athletes. Proximal tibiofibular instability, seems to be an infrequently diagnosed abnormality, which occurs in isolation or in combination with fractures of the leg and ankle. Tags: Surgical Techniques of the Shoulder Elbow and Knee in Sports 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. • All nonsurgical therapies should be attempted before surgical intervention. The proximal tibiofibular joint is ofte n neglected in the evaluation of lat-eral knee pain. • 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). - accept 1/6 the axial load of the leg. Injury to the proximal tibiofibular joint (PTFJ) is most … Related 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. 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. Atraumatic dislocation of the proximal tibiofibular joint is easily misdiagnosed when there is no clinical suspicion of the injury, owing to its association with a wide range of symptoms that mirror many common knee injuries. Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. It communicates with the knee joint in approximately 10% of adults, although communication in up to 64% has been reported with MR arthrography [].Because the proximal tibiofibular joint can be contiguous with the knee joint, either joint may be affected when the joint pressure is …
