BACKGROUND AND PURPOSE: Patients with knee osteoarthritis (OA) are commonly treated by physiotherapists in primary care. The physiotherapists use different treatment modalities. In a previous study, we identified variation in the use of transcutaneous electrical nerve stimulation (TENS), low level laser or acupuncture, massage and weight reduction advice for patients ...

BACKGROUND: Total knee arthroplasty can involve substantial blood loss. We prospectively studied a consecutive series of patients undergoing primary total knee arthroplasty to assess the influence of femoral cementing on perioperative blood loss. We hypothesized that an uncemented femoral component is a risk factor for bleeding. METHODS: A semiconstrained posterior ...

We analysed data from the Oxford hip and knee questionnaires collected by the New Zealand Joint Registry at six months and five years after joint replacement, to determine if there was any relationship between the scores and the risk of early revision. Logistic regression of the six-month scores indicated that ...

There is controversial evidence regarding whether foot orthoses or knee braces improve pain and function or correct malalignment in selected patients with osteoarthritis (OA) of the medial knee compartment. However, insoles are safe and less costly than knee bracing if they relieve pain or improve function. We therefore asked whether ...

Patient age, radiographic severity of osteoarthritis (OA), and severity of symptoms are typically considered as the three key factors in selecting the osteoarthritic patients for total knee arthroplasty (TKA). The purpose of this study was to evaluate the associations between the three selection criteria and the postoperative outcomes including patient ...

We analyzed alignment of 300 knees, divided equally into groups according to total knee arthroplasty technique: Conventional, CAS-Early (computer-assisted surgery during the surgeon's learning curve), and CAS-Late (after experience with CAS). With the margin of error for alignment of the mechanical axis and femoral and tibial components each within ±3°, ...

Varus malalignment after total knee replacement is mentioned to be a major risk factor for postoperative pain and functional impairments. This wide spread opinion is based on the historical data derived from implantations performed in the late 1970s and early 1980s. We tested the hypothesis whether significant varus malalignment leads ...

Osteonecrosis is a complication of corticosteroid therapy with limited treatment options in young, active patients. These options include debridement, core decompression, osteotomy, allografting, and partial or total knee replacement. Few studies exist regarding the use of osteochondral allografts for treatment of steroid-associated osteonecrosis. We asked if fresh osteochondral allografts would ...

The number of national arthroplasty registries is increasing. However, the methods of registration, classification, and analysis often differ. We combined data from 3 Nordic knee arthroplasty registers, comparing demographics, methods, and overall results. Primary arthroplasties during the period 1997-2007 were included. Each register produced a dataset of predefined variables, after ...

Use of an all-polyethylene tibial component in primary total knee arthroplasty remains an attractive option considering the reported durability of the construct, the lowered cost compared to modular metal-backed tibia, and the elimination of backside wear. The two major intra-operative disadvantages include the inability to alter the tibial component thickness ...

BACKGROUND: Individuals with hemiparesis resulting from cerebrovascular accident often demonstrate uncontrollable sliding of the paretic lower extremity when attempting to lift their pelvis from a hook-lying position (bridging), during bed mobility. This disorder is often attributed to hypertonicity of the knee extensors, though this assumption has not been confirmed experimentally. ...
