Arthroscopic partial meniscectomy versus placebo surgery for a degenerative meniscus tear: a 2-year follow-up of the randomised controlled trial.

Objective: To assess if arthroscopic partial meniscectomy (APM) is superior to placebo surgery in the treatment of patients with degenerative tear of the medial meniscus.

Methods: In this multicentre, randomised, participant-blinded and outcome assessor-blinded, placebo-surgery controlled trial, 146 adults, aged 35-65 years, with knee symptoms consistent with degenerative medial meniscus tear and no knee osteoarthritis were randomised to APM or placebo surgery. The primary outcome was the between-group difference in the change from baseline in the Western Ontario Meniscal Evaluation Tool (WOMET) and Lysholm knee scores and knee pain after exercise at 24 months after surgery.

Young age and wedge stem design are risk factors for periprosthetic fracture after arthroplasty due to hip fracture. A case-control study.

Background: It has been suggested that a hip fracture as a primary diagnosis for arthroplasty is a risk factor for periprosthetic fracture.

Patients And Methods: We compared 16 patients with late periprosthetic fracture of the femur to 48 controls. The primary diagnosis for all patients was hip fracture.

Factors predisposing to periprosthetic fracture after hip arthroplasty: a case (n = 31)-control study.

We compared retrospectively 31 patients with a periprosthetic fracture to 31 patients in a control group. The Finnish Arthroplasty Register was used to count all periprosthetic fractures treated by revision arthroplasty in Finland and in Tampere University Hospital district during the years 1990-1999. We used the date of the previous operation to find the control group patients operated on at the same time in the same hospital district.

Periprosthetic fractures in total hip arthroplasty: an epidemiologic study.

This study was based on data from the Finnish Arthroplasty Register. From 1990 to 1999, 33,154 primary hip arthroplasties were performed in Finland. Only periprosthetic fractures treated by a revision arthroplasty were registered.
