Neglected or chronic ruptures of the patellar tendon are defined as ruptures presenting after 6 weeks. Late presentation is often due to neglect or missed diagnosis. With chronic ruptures, the patient presents with weakness, instability, and pain. Management of patients with chronic ruptures is difficult due to adhesions, proximal patellar migration, contracture, and quadriceps muscle atrophy. ...

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 ...

PURPOSE Dyna-ATC is a unilateral external fixator with angulator, lengthener, and translator, which allows for angular correction and compensation of the secondary displacement during angular correction. The purpose of this study is to introduce surgical technique and calculation methods and to evaluate the clinical outcome of angular deformity correction using Dyna-ATC. MATERIALS AND METHODS...

OBJECTIVE To evaluate the clinical and functional results of a surgical treatment of patellar dislocation whose etiology was iatrogenic quadriceps fibrosis in children. MATERIALS AND METHODS A prospective study was undertaken from February 2004 to December 2009. The study included 54 pediatric patients (56 knees) that had developed dislocation of the patella after repeated intramuscular injec...

Introduction & Case: A 76 year old woman presented with a painful, valgus right knee measuring 49°. She had a simultaneous peri-articular femoral osteotomy and total knee arthroplasty. Pre and post operative WOMAC and VAS scores were obtained. Results: At 6 weeks, the patient was fully weight bearing without any aids; radiographs demonstrated bony union with good alignment. At one year, the pat...

The purpose of this study was to determine whether distraction osteogenesis can be used to treat hypertrophic nonunion associated with angular deformity and shortening after Coventry style high tibial osteotomy. Five consecutive patients were retrospectively reviewed. In all cases, the alignment had collapsed into excessive varus or valgus and leg length discrepancy was present. The leg length ...
