This study was designed to evaluate the effects of low-intensity pulsed ultrasound on bone regeneration during the bone-tendon junction healing process and to explore the application of synchrotron radiation micro computed tomography in three dimensional visualization of the bone-tendon junction to evaluate the microarchitecture of new trabecular bone. Twenty four mature New Zealand rabbits und...

We carried out three total knee replacements with proximal realignment in two patients with severe osteoarthritis of the knee and congenital dislocation of the patella. During the operation, the femur and the tibia were cut according to the recommendations of the manufacturer of the implant. The femoral component was placed in external rotation and the centre of the tibial component aligned in ...

Repair of a torn quadriceps tendon is necessary to restore the extensor mechanism of the knee. Traditional repair involves transosseous sutures tied over bone bridges on the inferior pole of the patella. Suture anchor repair has been shown to be stronger than transosseous repair and facilitates a smaller incision. Suture tape can improve the strength of the suture-tendon interface, and when com...

Patellar tendon rupture is an uncommon clinical presentation, which generally affects the under 40s who are active in sport. Bilateral rupture of both tendons is much rarer. It occurs most frequently in patients with predisposing factors such as corticosteroid use or systemic diseases. The authors present the case of a 56-year-old male on long-term statin therapy who sustained this injury follo...

INTRODUCTION Although patellar tendon injuries are common but chronic patellar tendon rupture are rare injuries but severely disabling. Problems associated with this injury are scar formation, atrophy and contracture of the quadriceps, poor quality of remaining reabsorbed tendon, inadequate soft tissue, proximal patellar migration and prolonged post operative immobilization. Hence these injurie...

Rupture of the extensor mechanism knee joints is rare in patients without any systemic disease. Many reports have described tendons getting ruptured at various sites mechanism. We report a case patellar tendon avulsion from tibial tuberosity on right side and quadriceps patella left sustained one accident. A 54 years old man presented with above non-identical bilateral rupture who had no pre-ex...

Background: The quadriceps tendon is crucial in allowing knee extension, attaching distally to the patella. While ruptures of are rare, retear can lead muscle atrophy and complex deficits with retraction which may make revision repairs difficult perform. To avoid re-rupture, repair commonly augmented an allograft or autograft, theoretically strengthening repair. Indications: Patients indicated ...

RATIONALE The patellar fractures are common in adults, but rare in children. As a particular type of patellar fracture, however, sleeve fractures are almost always limited to children in the under 16's group. PATIENT CONCERNS Herein, we report a rare case of a 19-year-old healthy adult female who presented sleeve fracture at the superior pole of the left patella. The clinical and radiological...

Patellofemoral crepitus and clunk syndrome are infrequent, yet troublesome complications of total knee arthroplasty with a reported incidence of 0%-18%. They are primarily associated with implantation of posterior cruciate substituting designs. These entities are the result of peripatellar fibrosynovial hyperplasia at the junction of the superior pole of the patella and the distal quadriceps te...
