A cementless femoral component may allow for a smaller surgical incision when a minimally invasive approach is used during primary total knee arthroplasty. Fixation by cement is the gold standard for total knee arthroplasty. The results of cementless total knee arthroplasty are mixed. Cementless femoral components have done well. Although some tibial components have performed well at long-term ...

INTRODUCTION One aim of modern pharmacologic treatment in rheumatoid arthritis (RA) is to prevent joint destruction and reduce the need for surgery. Our purpose was to investigate secular trends in the incidence of primary total hip and knee arthroplasties in a well defined sample of patients with RA. METHODS Prevalent cases with RA in 1997 and incident cases from 1997 to 2007 in a community ...

BACKGROUND AND PURPOSE Postoperative C-reactive protein (CRP) levels in serum appear to reflect surgical trauma. We examined CRP levels after 4 types of arthroplasty. MATERIAL AND METHODS We investigated 102 patients who had total knee arthroplasty (TKA), computer navigation-assisted total knee arthroplasty (NAV-TKA), hip resurfacing arthroplasty (metal on metal, MMSA) and total hip arthropla...

Background and purpose - 7% of the asymptomatic population has leg-length inequality (LLI) greater than 12 mm. It has been proposed that LLI of >5 mm can be associated with an increased risk of osteoarthritis (OA) of the knee and hip. We studied a possible association between LLI and OA of the knee and hip joint. Patients and methods - We followed 193 individuals (97 women, 96 men) for 29 years...

BACKGROUND Stable and well-aligned placement of tibial components during primary total knee arthroplasty is challenging in patients with bone defects. Although rectangular block-shaped augmentations are widely used to reduce the shearing force between the tibial tray and bone compared with wedge-shaped augmentations, the clinical result remains unclear. This study aimed to evaluate the outcome ...

OBJECTIVE We aimed to compare the efficacies of rehabilitation with the hybrid assistive limb and conventional rehabilitation after total knee arthroplasty. MATERIALS AND METHODS A total of 37 consecutive patients who underwent primary total knee arthroplasty for knee osteoarthritis were enrolled. Seven patients withdrew from the study after randomization, and 30 patients (hybrid assistive li...

BACKGROUND Unicompartmental knee arthroplasty is a less-invasive alternative to total knee arthroplasty for patients with arthritis affecting only the medial or lateral compartment. However, little is known about recent trends in the use of these procedures and the associated outcomes among older patients. METHODS With use of a nationally representative 5% sample of Medicare beneficiaries who...

BACKGROUND Utilization of total knee arthroplasty is increasing rapidly. A substantial number of total knee arthroplasty recipients have persistent pain after surgery. Our objective was to design a randomized controlled trial to establish the efficacy of a motivational-interviewing-based telephone intervention aimed at improving patient outcomes and satisfaction following total knee arthroplast...

Soft-tissue balancing during total knee arthroplasty is an important step in optimizing the mechanical balance of the knee joint. Soft-tissue contractures that result from varus coronal plane deformity can pose a difficult problem, and the surgeon should have a standard procedure for managing such situations in the operating room. Balance may be assessed intraoperatively with the use of spacer ...

BACKGROUND Although early aseptic mechanical failure after total knee arthroplasty has been reported in younger patients, it is unknown whether early revision due to periprosthetic joint infection is more or less frequent in this patient subgroup. The purpose of this study was to determine whether the incidence of early periprosthetic joint infection requiring revision knee surgery is significa...
