BACKGROUND The Knee injury and Osteoarthritis Outcome Score (KOOS) is an extension of the Western Ontario and McMaster Universities Osteoarthrtis Index (WOMAC), the most commonly used outcome instrument for assessment of patient-relevant treatment effects in osteoarthritis. KOOS was developed for younger and/or more active patients with knee injury and knee osteoarthritis and has in previous st...

PURPOSE OF THE STUDY The kinematics of an intact knee joint and that of a knee replacement have been studied in many research centres. In the 1987 radiographic study, Bradley, Goodfellow and O'Connor reported the movement of a polyethylene insert in patients with unicompartmental Oxford knee replacement. Views with the knee at full extension and 90° of flexion were obtained and the movement of ...

OBJECTIVES This study aimed to describe patients treated for knee osteoarthritis between 2006 and 2013 in France and to compare the delay from diagnosis to total knee replacement between patients who received intra-articular hyaluronic acid injections and those who did not receive the injections. A second objective was to compare direct medical costs for ambulatory care between treatment groups...

OBJECTIVES This article examines trends in hip and knee replacement surgery between 1981/82 and 1998/99, focussing on procedures involving seniors. It also presents 1998/99 data on readmissions within 30 days. DATA SOURCES Data on hip and knee replacement are from the Hospital Morbidity Database for 1981/82 through 1998/99. The Person-oriented Information Database is used to examine readmissi...

BACKGROUND Studies on leisure time physical activity as risk factor or protective factor for knee or hip osteoarthritis (OA) show divergent results. Longitudinal prospective studies are needed to clarify the association of physical activity with future OA. The aim was to explore in a prospective population-based cohort study the influence of leisure time physical activity on severe knee or hip ...

Infection remains a significant and common complication after joint replacement and there is debate about which contributing factors are important. Few studies have investigated the effect of the operating time on infection. We collected data prospectively from 5277 hip and knee replacements which included the type of procedure, the operating time, the use of drains, the operating theatre, surg...

Two major obstacles to using motion analysis as an aid to clinical decision making are the subjectivity of data interpretation and the difficulty in comprehending large amounts of both corroborating and conflicting information. In response to these findings a diagnostic tool was developed that is capable of producing an automated and objective diagnosis from large amounts of motion analysis dat...

There has been increasing interest in performing acute total knee replacement for periarticular knee fractures in elderly osteoporotic patients. This is comparable to treating femoral neck fractures with arthroplasty. We present a case of tuberculous infection in a primary total knee replacement performed for a medial tibial condyle fracture, in an 85-year-old Caucasian female with a previously...
