A Prospective, Single-arm, Trial to Determine Contamination Rates When Using an Antibacterial Incise Drape During Orthopedic Surgery

The goal of this clinical study is to generate data on the intended use of a chlorhexidine gluconate (CHG)-impregnated antimicrobial incise drape. The study includes subjects undergoing primary hip or knee arthroplasty procedures. The study evaluates the intraoperative performance and safety of the incise drape during surgery, including assessment of contamination and operative characteristics. Participants will have a CHG-impregnated antimicrobial incise drape applied during their surgical procedure. During surgery, samples will be collected from the operative site to assess potential bacterial contamination.

Development and Measurement of the Effects of a Digital Education Solution for Patients Undergoing Total Hip or Knee Arthroplasty

This study aims to evaluate the effectiveness of a digital patient education solution, CHUVeduc@home, in improving preoperative preparation for patients undergoing total hip or knee arthroplasty. In Switzerland, many patients receive joint replacements each year to relieve osteoarthritis-related pain. With shorter hospital stays, adequate preparation before surgery has become increasingly important. A total of 160 patients will be randomized into two groups: Intervention group: access to CHUVeduc@home before surgery. Control group: standard preoperative preparation (group information session and consultation). All participants will complete questionnaires through the application. No additional visits are required. The intervention lasts approximately 12 weeks. The primary goal is to determine whether digital education increases patient knowledge, confidence, and satisfaction, and facilitates recovery and return home after surgery. Participation is voluntary and can be withdrawn at any time.

Return to Sports After Knee Arthroplasty

The ability to return to sports after joint arthroplasty is increasingly becoming an important factor for patients in terms of their perceived quality of life. In sports orthopaedics, standardized functional tests have already been established - particularly for anterior cruciate ligament injuries - to assess athletic performance and prevent re-injury. These tests allow a stepwise evaluation of a subject's physical readiness for sports. In the field of arthroplasty, and despite increasing sports activity among patients with joint arthroplasty such structured assessment is still lacking. As a result, patients with arthroplasty typically resume sports activities based solely on individual recommendations from the surgeon or treating therapist. However, an objective evaluation of sports capability is currently not available. Therefore the amendment intends to expand the current testing protocol of the already registered and ongoing study (Protocol ID: UBonn\_TKA\_FollowUp) to include additional standardized, evidence-based return-to-sprort-tests.
