Importance: There is a paucity of high-quality evidence about the long-term effects (ie, 3-5 years and beyond) of arthroscopic partial meniscectomy vs exercise-based physical therapy for patients with degenerative meniscal tears. Objectives: To compare the 5-year effectiveness of arthroscopic partial meniscectomy and exercise-based physical ther...
Article
Objective Anxiety, depression and greater pain intensity before total knee arthroplasty (TKA) may increase the probability of revision surgery for remaining symptoms even without clear pathology or technical issues. We aimed to assess whether preoperative anxiety/depression and pain intensity are associated with revision TKA for less clear indicati...
Article
Background: Femoral neck fractures are common and are frequently treated with internal fixation. A major disadvantage of internal fixation is the substantially high number of conversions to arthroplasty because of nonunion, malunion, avascular necrosis, or implant failure. A clinical prediction model identifying patients at high risk of conversion...
Article
Background: The influence of bearing on revision, especially in press-fit modular cup total hip arthroplasty (THA), remains underexposed. Methods: A systematic literature review was conducted in PubMed, Embase, Cochrane Library and ClinicalTrials.gov in line with the PRISMA guidelines. Primary outcome was overall revision between ceramic-on-cerami...
