PURPOSE To present midterm results of Duracon total knee arthroplasty (TKA) performed between 1991 and 2001. METHODS One man and 43 women (65 knees) aged 46 to 84 (mean, 63) years who underwent primary TKAs using the Duracon prosthesis performed by a single surgeon were followed up for a mean of 8.5 (range, 5-11) years. All TKAs were cruciate-retaining and cemented, with only 9 of the patella...

Varus malalignment after total knee replacement is associated with a poor outcome. Our aim was to determine whether the same was true for medial unicompartmental knee replacement (UKR). The anatomical leg alignment was measured prospectively using a long-arm goniometer in 160 knees with an Oxford UKR. Patients were then grouped according to their mechanical leg alignment as neutral (5 degrees t...

BACKGROUND Gel-type autologous chondrocyte (Chondron) implantations have been used for several years without using periosteum or membrane. This study involves evaluations of the clinical results of Chondron at many clinical centers at various time points during the postoperative patient follow-up. METHODS Data from 98 patients with articular cartilage injury of the knee joint and who underwen...

BACKGROUND The treatment of isolated patellofemoral arthritis is controversial. Several surgical procedures have been used to treat the severely degenerated patellofemoral joint, with varying degrees of success. The purpose of this study was to determine the clinical results of a custom patellofemoral arthroplasty for the treatment of isolated patellofemoral degenerative arthritis of the knee. ...

A new total knee rating system has been developed by The Knee Society to provide an up-to-date more stringent evaluation form. The system is subdivided into a knee score that rates only the knee joint itself and a functional score that rates the patient's ability to walk and climb stairs. The dual rating system eliminates the problem of declining knee scores associated with patient infirmity.

We present a prospective review of the two-year functional outcome of 37 Avon patellofemoral joint replacements carried out in 29 patients with a mean age of 66 years (30 to 82) between October 2002 and March 2007. No patients were lost to follow-up. This is the first independent assessment of this prosthesis using both subjective and objective analysis of outcome. At two years the median Oxfor...

The PFC Sigma total knee was introduced in 1997, incorporating a number of design changes. We report the mid-term results of a consecutive series of PFC Sigma knee arthroplasties performed between November 1997 and December 1998. Out of a total of 156 patients (166 knees), 5 patients (5 knees) were lost to follow-up and 6 patients (6 knees) died of unrelated causes. This left 145 patients (155 ...

OBJECTIVES To introduce the practice of a nurse-led orthopaedic clinic for managing stable patients after total hip or knee replacement and to evaluate its efficacy. DESIGN Case series. SETTING A public hospital in Hong Kong. PATIENTS Patients who had stable primary total knee replacement or total hip replacement done for longer than 2 years were managed in a nurse-led total joint replace...

INTRODUCTION The use of patient reported outcome measures (PROMs) for four elective operations is mandatory in the English NHS from April 2009. In view of some scepticism by some clinicians as to the validity of PROMs, our aim was to explore the relationship between patients' and clinicians' reports of health status before and after knee arthroplasty. METHODS A secondary analysis of linked da...

PURPOSE To identify preoperative factors (including surgeon factors) associated with outcome scores after total knee arthroplasty (TKA). METHODS Medical records of 2848 patients (3458 knees) who underwent primary TKA by 27 orthopaedic specialists were retrieved. Three specialty knee surgeons who had one-year fellowship in TKA performed 1930 TKAs, and 24 general orthopaedic surgeons performed ...
