[caption id="attachment_73589" align="alignleft" width="200"] Dr. Järvinen[/caption] MedicalResearch.com Interview with: Teppo Järvinen MD PhD Professor of Orthopaedics and Traumatology University of Helsinki, HUS MedicalResearch.com: What is the background for this study? Response: Arthroscopic partial meniscectomy (APM) is one of the most frequently performed orthopedic procedures worldwide, particularly for middle-aged and older patients with knee pain and a degenerative meniscal tear. Over the past 15–20 years, multiple randomized trials have questioned the effectiveness of this procedure, showing no meaningful benefit compared with non-operative care (typically, exercise or physical therapy) or even placebo (sham) surgery in the short to medium term. Our study reports the 10-year follow-up of the FIDELITY trial, a randomized, placebo-surgery controlled trial.
