Ligamentous injuries of the knee occur during sports and where there is extensive injury associated with subluxation or dislocation. We present a case of an obese female who sustained spontaneous non-traumatic posterior knee dislocation when she caught her foot while rising from the sitting down position. There was associated peroneal nerve injury but an angiogram confirmed no vascular compromi...

Background: Patellar dislocation accounts for 2–3% of all knee lesions and is the second most common cause traumatic hemarthrosis knee. Proper treatment essential to minimize long term sequelae, such as recurrent dislocation, painful subluxation, osteoarthritis. Aim: The purposes this perspective randomized study were: 1) evaluate mid-term clinical radiological results Elmslie–Trillat procedure...

The management of osteoarthritis of the knee associated with patellar instability secondary to external tibial torsion > 45 degrees is challenging. Patellofemoral biomechanics in these patients cannot be achieved by intra-articular correction using standard techniques of total knee replacement. We reviewed seven patients (eight knees) with recurrent patellar dislocation and one with bilateral i...

INTRODUCTION Total knee arthroplasty is a well-established procedure with gratifying results. There is no consensus in the literature whether to routinely resurface the patella while performing total knee arthroplasty or not. Although an extremely rare occurrence in clinical practice, patellar prosthesis dislocation is a possible complication resulting from total knee arthroplasty. CASE PRESE...

Knee dislocation after total knee arthroplasty (TKA), although rare, is a dangerous injury that can lead to neurovascular compromise and permanent disability. Chronic dislocation after TKA is even less common and is defined as dislocation that is present for 4 weeks or more. There are few reports of its management. Chronic dislocation may be complicated further by concomitant extensor mechanism...

INTRODUCTION The injury of the cruciate ligaments secondary to knee dislocation is caused by high energy trauma; its incidence rate is less than 0.02%; there are multiple treatments, with surgery being the most common one. OBJECTIVE To determine the functional characteristics of patients who underwent cruciate ligament plasty and sustained knee dislocation. MATERIAL AND METHODS An observati...

Recurrent dislocation of the patella probably has several causes. In many patients abnormal laxity of the knee is present and this may predispose to dislocation (Dc Palma 1954). A family has come to our notice in which three members suffered recurrent dislocation of the patella and a fourth had probably sustained a single dislocation. All the former had abnormally lax knees and most other joint...
