A variety of surgical treatments have been proposed over the last decades. Injury to the proximal tibiofibular joint can lead to lateral knee pain and instability owing to chronic rupture of the posterior tibiofibular ligament. An often overlooked contributor to • All other clinical possibilities should be ruled out before a diagnosis is made. - subluxation is common in preadolescent females and resolves with skeletal maturity. • Proximal tibiofibular joint instability is a very unusual and uncommon condition. In chronic injuries, the instability … The treatment of proximal tibiofibular joint instability usually depends upon whether it is an acute or chronic injury. Clinical Presentation • Atraumatic instability is more common and often misdiagnosed. The early recognition of instability in the proximal tibiofibular joint is necessary to optimize management of the injury and to avoid potential misdiagnosis. Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. 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 We anticipate that our patients will return back to full activities about 4-5 months after surgery, following the rehabilitation program. Only gold members can continue reading. Protection of the peroneal nerve during surgery helps to prevent injury and relieves symptoms common to this injury. A closed reduction should be attempted in patients with acute dislocation. Management of Proximal Tibiofibular Instability 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 … Tags: Surgical Techniques of the Shoulder Elbow and Knee in Sports may play a role in chronic ankle instability dysfunc-tion. 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. After 6 weeks postoperatively, patients may start to use a stationary bike with low resistance. Clinical and Surgical Pitfalls 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. 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. We have found it to be very effective at restoring stability to this joint and not resulting in joint overconstraint. 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. • The reconstructive procedure is recommended for patients whose pain is a result of joint instability. 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 Patient History 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]. The condition is often missed, and the true incidence is unknown. 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. Copyright © 2021 IKOC. Although the … The diagnosis of proximal tibiofibular joint instability is almost always based on a thorough clinical exam. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. Suspicion of atraumatic injury to the proximal tibiofibular joint warrants extensive inspection during the physical examination of the knee. 1973;55(1):177-183. Traumatic dislocations of the proximal tibiofibular joint are uncommon and are normally caused by high-energy injury or a fall on a twisted knee. 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 capsule is reinforced anteriorly and posteriorly by two ligaments. Isolated acute dislocation of the proximal tibiofibular joint. - accept 1/6 the axial load of the leg. The proximal tibio-fibular joint consists of a joint cavity surrounded by a joint capsule (diarthrosis) forming a rather rigid joint. Unfortunately, since the patient presented with advanced degenerative changes at her initial evaluation, it was not possible to assess the degree to which joint instability may have contributed to the development of her condition. Proximal tibiofibular joint instability (PTJI) is increasingly reported in the literature. 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. Important Points Injury to the proximal tibiofibular joint can lead to lateral knee pain and instability owing to chronic rupture of the posterior tibiofibular ligament. Suspicion of atraumatic injury to the proximal tibiofibular joint warrants extensive inspection during the physical examination of the knee. 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. 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. 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. 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. Fibular resection during an arthrodesis procedure can decrease ankle pain and instability after surgery. 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. 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. 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. J Bone Joint Surg Am. 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 most common traumatic dislocations are in an anterolateral direction, followed by posteromedial and superior dislocations. Imaging Techniques Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. The diagnosis of proximal tibiofibular joint instability is almost always based on a thorough clinical exam. Suspicion of atraumatic injury to the proximal tibiofibular joint warrants extensive inspection during the physical examination of the knee. The proximal tibiofibular joint is located between the lateral tibial plateau of the tibia and the head of the fibula. Proximal tibiofibular joint instability is a very unusual and uncommon condition. Although many patients do not note symptoms during daily activities, symptoms may develop during activities that require sudden changes in direction. Traumatic dislocations of the proximal tibiofibular joint are uncommon and are normally caused by high-energy injury or a fall on a twisted knee. Concurrent with this, we will perform a Tinel’s test by percussing over the common peroneal nerve to confirm the presence of dysesthesias or “zingers,” which translate down the leg. It is important to compare the injured side to the normal contralateral side because some patients may have physiologic laxity of this joint. The images presented in this artic le highlight the diverse disorders of this area. Background & Purpose: The knee is the most common site of injury in running athletes. 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. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. All nonsurgical therapies should be attempted before surgical intervention. • The reconstructive procedure is recommended for patients whose pain is a result of joint instability. Instability of the joint can be a result of an injury to these ligaments. Symptoms of an Injured Proximal Tibiofibular Joint: Instability of the joint, especially during Four types of instability are distinguished: subluxation, anterolateral dislocation, posteromedial dislocation and superior dislocation. Injury to the proximal tibiofibular joint (PTFJ) is most … History and physical examination are very important for diagnosis. • Fibular resection during an arthrodesis procedure can decrease ankle pain and instability after surgery. Keywords Proximal tibiofibular joint instability ! Proximal tibiofibular arthrodesis and fibular head resection 7,12 to treat proximal tibiofibular joint instability have been associated with changes in ankle biomechanics and loading, thus leading to pain and reduced function. • Resecting and protecting the peroneal nerve during surgery can prevent peroneal nerve palsy. The most common traumatic dislocations are in an anterolateral direction, followed by posteromedial and superior dislocations. Proximal tibiofibular instability, seems to be an infrequently diagnosed abnormality, which occurs in isolation or in combination with fractures of the leg and ankle. • 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. If this is unsuccessful, open reduction and stabilization of the joint … • Dislocation of the proximal tibiofibular joint is a very uncommon condition that is easily misdiagnosed without clinical suspicion of the injury. The most common traumatic dislocations are in an anterolateral direction, followed by posteromedial and superior dislocations. Proximal tibiofibular instability is a rarely reported clinical entity in children. The examination of patients with atraumatic subluxation or chronic instability should be performed with the knee flexed to 90 degrees. Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. - resist torsional stresses originating from the ankle. 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. Knee injury Introduction Proximal tibiofibular subluxation is a rare condition. Doi: 10.2106/00004623-197355010-00019 ; Gvozdenović N, … In more chronic cases, we have the patient squat down, which can often demonstrate that the proximal tibiofibular joint is being subluxed. Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. Conservative treatment with immobili-zation is … Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. She is noted to have a posterior and inferior instability pattern. - Discussion: - function of the PTFJ. • 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). Reconstructive procedures are recommended for patients whose source of pain is instability in the joint as opposed to arthritis. The proximal tibiofibular joint ligaments both strengthen the joint and allow it to rotate and translate during ankle and knee motion. he proximal tibiofibular joint is a source of lateral … You may also needAnatomic Acromioclavicular Joint ReconstructionArthroscopic Lateral Retinacular Release and Lateral Retinacular LengtheningArthroscopic and Open Management of Scapulothoracic DisordersMedial Patellofemoral Ligament Reconstruction and Repair for Patellar InstabilityManagement of Pectoralis Major Muscle InjuriesCombined Anterior Cruciate Ligament Reconstruction and High Tibial OsteotomyPosterolateral Corner ReconstructionPatient Positioning, Portal Placement, and Normal Arthroscopic Anatomy In most circumstances, it is the posterior proximal tibiofibular joint ligament that is injured. 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. &NA; Injury to the proximal tibiofibular joint is typically seen in athletes whose sports require violent twisting motions of the flexed knee. 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. • Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. Clinical and Surgical Pearls Joint mobilization or manipulation may offer the ability to restore normal joint arthrokinematics and improve function. The relative avascularity of the area of the proximal tibiofibular joint prevents the presentation of knee effusion with an isolated injury, but there may be a prominent lateral mass.
