Arterial complications following traumatic knee injury are relatively rare but mandate timely recognition and treatment to avoid significant comorbidity and medicolegal ramifications. In this report we describe a case of acute thrombotic occlusion of the popliteal artery occurring after knee dislocation, successfully repaired by intimal fixation and a limited venous patch reconstruction. We pre...

INTRODUCTION One of the primary functions of the proximal tibiofibular joint is slight rotation to accommodate rotational stress at the ankle. Proximal tibiofibular joint dislocation is a rare injury and accounts for less than 1% of all knee injuries. This dislocation has been reported in patients who had been engaged in football, ballet dancing, equestrian jumping, parachuting and snowboarding...

Acute patellar dislocation is a common injury in young athletes, which occurs due to inappropriate biomechanical relations and anatomic deviations in the area of knee joint. In these unfavorable conditions, abrupt and vigorous strain of the quadriceps muscle of the thigh may result in lateral patellar dislocation. A case is presented of a young male athlete with acute patellar dislocation and c...

Permanent patellar dislocation with tibiofemoral joint osteoarthritis is a relatively rare condition. To treat this condition, total knee arthroplasty with proximal or distal realignment of the extensor mechanism has been reported. We report a challenging case of an 80-year-old woman diagnosed with permanent patellar dislocation with tibiofemoral joint osteoarthritis treated by a mobile bearing...

Introduction Chronic post-traumatic dislocation of the patella is rare and results in persistent dislocation throughout the arc of motion of the knee. Whereas newborns with trochlear dysplasia may exhibit congenital patellar dislocation, typical delayed presentation in adults is often due to trauma and can progress to painful motion and secondary osteoarthritis. Although rare, recurrent disloca...

BACKGROUND AND PURPOSE Several mechanisms are responsible for patellar dislocation. We investigated how the primary pathomechanism relates to patient characteristics and the outcome. METHODS 126 patients (81 females) with primary patellar dislocation reported the knee position before the episode, the movement during it, and whether the patella was locked in dislocation. The median age was 20 ...

Congenital permanent dislocation of the patella is a rare disorder of the knee joint in which the patella is permanently displaced, even in extension and is fixed on the lateral aspect of the femoral condyle. The dislocation is irreducible without surgical techniques. This rare condition is usually detected within the first decade of life, because of inability of active extension in the knee an...

Knee dislocations are uncommon as isolated orthopaedic injuries, but their prevalence is increased in the setting of high-energy multiple trauma. In these circumstances, it is important for the orthopaedic clinician to recognize and appropriately treat the knee dislocation in parallel with other significant injuries. We report the case of an 18-year-old woman who was involved in a motor vehicle...

UNLABELLED We report here a unique case of a 3 year neglected rotatory tibiofemoral dislocation associated with a lateral patellar dislocation. The rotational deformity was gradually corrected using a Taylor spatial frame and the patella was realigned by tibial tubercle osteotomy and transfer. The patient also underwent multiple soft tissue releases and quadricepsplasty to improve knee flexion....
