conversion of knee arthrodesis to total knee arthroplasty is a difficult procedure accompanied by many complications due to soft tissue and extensor mechanism contracture and bone defects. we report two cases of distal femur osteosarcoma that had been undergone wide resection arthrodesis initially. arthrodesis was converted to total knee arthroplasty with hinged prosthesis after many years. we ...

One hundred and twenty adult patients were reviewed in whom split skin grafts were applied to the stump following traumatic amputation of the upper limb (44 amputees) or lower limb (76 amputees). The average follow-up period was seven and a half years after initial amputation. There was delay in prosthetic fitting in all patients. Approximately one third of patients complained of occasional min...

With the development of the patellar-tendon-bearing prosthesis by the University of California at Berkeley, many new advantages in simplicity, comfort, and function were available to the below-knee amputee. However, there still exists the problem of concentrated pressures over small areas of the stump. The original design of the patellar-tendonbearing prosthesis was intended to distribute the l...

Background. Our study aimed to analyze retrospectively the locomotion performance in patients following below-the-knee amputation (BKA) for atherosclerotic critical limb ischaemia (CLI) in relation to factors which may influence the final outcome. Material and methods. Two groups of patients were analyzed: Group I (n = 53), which underwent fitting of prosthesis and rehabilitation immediately af...

In this work, a magnetic measurement system was designed and tested to estimate the InternalExternal rotation between the Tibial and Femural parts of a knee prosthesis. To obtain this, the sensors were inserted in polyethylene part while a permanent magnet was placed below the Tibial plate. The configuration was designed to keep the intrinsic unbiassness to the positive and negative internalext...

The Dundee Limb Fitting Centre has provided an integrated rehabilitation programme for the amputee since 1965. A review of 1846 primary amputees is discussed. During this period a dramatic change in the above-knee/below-knee (AK/BK) ratio has been achieved with 71% BK and 26% AK occurring in 1989. Over 80% of all amputees, the majority being elderly with peripheral vascular disease, were succes...

A patient, sent from a VA hospital, was seen at the VAPC Special Clinic for evaluation and prescription. He was not considered a good candidate for a prosthesis, since his condition was beyond what is generally accepted as a "good risk." Normally, SO deg. of flexion contracture is considered a maximum limit for fitting of below-knee amputees. This patient exceeds this maximum by almost 40 deg. ...
