The primary function of the patella is to increase the effi cacy of the quadriceps muscle by elevating the extensor mechanism from the knee’s axis of rotation.1 This provides a mechanical advantage by increasing the moment arm, thus allowing the knee to tolerate the substantial forces required by activities such as walking, rising from a chair, or jumping.1 This mechanism is often disrupted in ...

INTRODUCTION Pathological bilateral femoral neck fracture due to renal osteodystrophy is rare. This is a report of a chronic renal failure patient who had sustained bilateral intra-capsular displaced fracture neck of femur following an episode of convulsion and the difficulties encountered in early diagnosis and treatment. The pathophysiology of renal osteodystrophy and the treatment of hip fra...

Eighteen patients with acute dislocation of the patella had associated osteochondral fractures. This fracture complicates approximately 5% of all acute dislocations of the patella occurring in children. Three types of fracture patterns were noted. All patients who were treated by immediate arthrotomy and excision or replacement of the osteochondral fragment and repair of the acute dislocation o...

Patellar taping is a treatment adjunct commonly used in the management of anterior knee pain. The aim of this cross sectional study was to investigate the effects of medial glide patellar taping on sagittal plane lower-limb joint kinematics and knee pain during a unilateral squat in a symptomatic population complaining of anterior knee pain. Ten participants with a history of unilateral or bila...

Treatment of type II periprosthetic patellar fractures presents difficulties in decision-making particularly when displacement is greater than 10 mm. Poor results have been reported with internal fixation, whereas conservative management has been associated with a high incidence of extensor lag. This article reports a patient with a displaced type II patellar fracture following total knee arthr...

Bilateral patellar tendon rupture is usually associated with systemic immunologic or connective tissue disease, steroid use, fluoroquinolone antibiotic use, or renal disease. Amongst the spontaneous cases, bilateral ruptures are exceedingly rare and have only been documented in a few case reports. We present a case of bilateral midsubstance patellar tendon ruptures along from a fall from a stan...
