Decreasing incidence of knee arthroscopy in Sweden between 2002 and 2016: a nationwide register-based study.

Background And Purpose: Several randomized trials have demonstrated the lack of effect of arthroscopic lavage as treatment for knee osteoarthritis (OA). These results have in turn resulted in a change in Swedish guidelines and reimbursement. We aimed to investigate the use of knee arthroscopies in Sweden between 2002 and 2016.

Younger patients and smokers report a higher level of pain after knee arthroscopy: a clinical and experimental study including synovial metabolism.

Purpose: Factors associated with post-surgical pain are not fully explored. The aim of this study was to identify determinants of postoperative pain after arthroscopic surgery of the knee. Synovial tissue metabolism was analysed by microdialysis and the association with individual and peri-surgical factors to identify determinants important for pain management and thus patient satisfaction.

[»Shermer's neck« is a rare injury in long-distance cycle races. Association with diplopia described for the first time].

Shermer's neck was first described in 1983 in an ultra-distance cyclist and it is often associated with neck pain (in our patient diplopia as first symptom) and exhaustion and impaired neck motor function with inability to extend the neck against gravity. The diplopia, for the first time described in connection with Shermer's neck, was accentuated when elevating the eyes and looking at distance, most likely reflecting exhaustion in the elevator muscles of the eye. Shermer's neck usually appears after 800 km of non-stop bike racing.

Temperature-sensitive release of prostaglandin E₂ and diminished energy requirements in synovial tissue with postoperative cryotherapy: a prospective randomized study after knee arthroscopy.

Background: Local external cooling of the surgical field after joint surgery is intended to enhance recovery and to facilitate the use of outpatient surgery by reducing pain and improving mobility. We hypothesized that the effects of postoperative cooling and compression after knee arthroscopy would be reflected in changes in the concentrations of metabolic and inflammatory markers in the synovial membrane.

Methods: Forty otherwise healthy patients who were to undergo knee arthroscopy were included in the study, and half were randomized to receive postoperative cooling and compression.

Special attention to the weight-control strategies employed by Olympic athletes striving for leanness is required.

Background: Optimization of body weight and composition is a key priority for elite athletes striving for a competitive advantage. The present investigation was designed to characterize various parameters related to weight control in Olympic competitors.

Design: Cross-sectional study.
