We identified 148 patients who had undergone a revision total knee replacement using a single implant system between 1990 and 2000. Of these 18 patients had died, six had developed a peri-prosthetic fracture and ten had incomplete records or radiographs. This left 114 with prospectively-collected radiographs and Bristol knee scores available for study. The height of the joint line before and af...

The aims of this study were to determine the complexity of surgery required to revise failed unicompartmental knee replacements and to evaluate the outcome following revision. Between 2000 and 2009, 494 cemented Oxford phase 3 medial unicompartmental knee replacements were implanted, with 24 (4.9%) requiring revision (mean age: 63.5 years; 58% male). Mean time to revision was 3.0 years. All cas...

a 48‑year‑old morbidly obese woman with a left medial meniscal tear and moderately severe degenerative joint disease (djd) reported for 14‑month follow‑up visit from arthroscopic surgery. she reported a resolution of pain, swelling and an improved range of motion (rom). the patient was first evaluated 14 months ago, and at that time was considered a strong candidate for total knee replacement d...

The human knee joint can sustain damage due to injury, or more usually osteoarthritis, to one, two or all three of the knee compartments: the medial femorotibial, the lateral femorotibial and the patellofemoral compartments. When pain associated with this damage is unmanageable using nonsurgical techniques, knee replacement surgery might be the most appropriate course of action. This procedure ...

OBJECTIVES To examine the effect of height, weight and body mass index (BMI) on the risk of hip and knee replacement in middle-aged women. METHODS In a prospective cohort study 490 532 women aged 50-69 yrs who were recruited in the UK in 1996-2001 were followed over 2.9 yrs for incident primary hip and knee replacements. RESULTS Height, weight and BMI were all associated with the risk of hi...

BACKGROUND There is emerging evidence for a beneficial effect of meat consumption on the musculoskeletal system. However, whether it affects the risk of knee and hip osteoarthritis is unknown. We performed a prospective cohort study to examine the relationship between meat consumption and risk of primary hip and knee replacement for osteoarthritis. METHODS Eligible 35,331 participants were se...

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...

The objective of this study was to determine if disparities in hip and knee replacement surgery exist among osteoarthritis patients with AARP-branded Medicare supplement plan (ie, Medigap) coverage provided by UnitedHealthcare. Patients were selected into the study if they had 1 or more medical claims with a diagnosis of osteoarthritis from July 1, 2006 to June 30, 2007. Logistic regression ana...

We audited the relationship between obesity and the age at which hip and knee replacement was undertaken at our centre. The database was analysed for age, the Oxford hip or knee score and the body mass index (BMI) at the time of surgery. In total, 1369 patients were studied, 1025 treated by hip replacement and 344 by knee replacement. The patients were divided into five groups based on their BM...
