Background: In the light of increasing skin cancer incidences worldwide, preventive measures to promote sun protection in individuals with risky sun habits have continued relevance and importance. Aim: To report the long-term effect of individualised sun protection advice given in primary health care (PHC), on sun habits and sun protection behav...

OBJECTIVE Information about postoperative rehabilitation for cervical radiculopathy (CR) is scarce. The aim of this study was to investigate the additional benefits of structured postoperative rehabilitation (SPT), which was performed in all patients, compared with a pragmatic standard postoperative approach (SA), in which rehabilitation was used a...

Objective Findings from individual anterior cruciate ligament reconstruction (ACLR) registry studies are impactful, but how various registries from different countries compare with different patient populations and surgical techniques has not been described. We sought to describe six ACLR registry cohorts to understand variation across countries....

Purpose: To analyze and compare clinical outcomes after anterior cruciate ligament (ACL) reconstruction 5 and 10 years postsurgery between patients with concomitant intra-articular injuries and those with isolated ACL injury at reconstruction. Methods: Registrations were made using a web-based protocol by physicians for baseline and surgical dat...

Background: The optimal treatment for middle-aged patients with knee pain and meniscal lesions has been extensively debated. Most previous studies have revealed only short-term beneficial results of knee arthroscopic surgery. The authors have previously shown a positive benefit of knee arthroscopic surgery and an exercise program after 1 year when...
