BACKGROUND Whilst patellofemoral pain is one of the most common musculoskeletal disorders presenting to orthopaedic clinics, sports clinics, and general practices, factors contributing to its development in the absence of a defined arthropathy, such as osteoarthritis (OA), are unclear.The aim of this cross-sectional study was to describe the relationships between parameters of patellofemoral ge...

Anterior dislocation of a posterior stabilised total knee arthroplasty secondary to a polyethylene tibial post fracture is rare. We report one such case in an 89-year-old Chinese woman who had undergone total knee arthroplasty using the Insall Burstein II prosthesis 7 years earlier. The failure was due to sagittal malalignment of the components. Owing to more pronounced anterior bowing of the d...

OBJECTIVES The aim of this study is to evaluate the efficacy of the central (transpatellar tendon) portal technique for the treatment of isolated medial bucket-handle type meniscal tears with the arthroscopic menisectomy procedure. PATIENTS AND METHODS In this study, fifty patients with isolated medial bucket-handle type meniscal tears were evaluated. They were divided into two groups with 25...

In 1861, Ferguson reported a resection arthroplasty as treatment for severe arthritis of the knee [1]. To our knowledge this was the first report of a surgical intervention to treat arthritis. In the late 18th century, Verneuil performed an interposition arthroplasty of the knee, when he used flaps of joint capsule to cover resected articular surfaces in an attempt to decrease the pain and incr...

The purpose of this study is to determine if patellar maltracking is more prevalent among patellofemoral (PF) pain subjects with patella alta compared to subjects with normal patella height. We imaged 37 PF pain and 15 pain free subjects in an open-configuration magnetic resonance imaging scanner while they stood in a weightbearing posture. We measured patella height using the Caton-Deschamps, ...

BACKGROUND High tibial osteotomy (HTO) is a well established technique for the treatment of medial osteoarthritis of the knee with varus malalignment. Results of total knee arthroplasty (TKA) after previous HTO are still discussed controversially. The aim of this study was to elucidate the clinical and radiological results as well as perioperative data of prior HTO on TKA. METHODS Forty-one T...
