Clinical Outcomes of Arthroscopic Surgeries for Shoulder and Knee Sports Injuries

Despite significant advancements in arthroscopic techniques for shoulder and knee sports injuries (e.g., anterior cruciate ligament reconstruction, meniscus repair, and rotator cuff repair), postoperative clinical outcomes and return-to-sport rates remain highly variable among individuals. This variability is likely influenced by a complex interplay of patient baseline characteristics, specific tear morphologies, individualized intraoperative surgical choices (e.g., mechanical augmentation strategies, remnant preservation), and post-operative rehabilitation. This single-center, prospective observational cohort study is designed to systematically collect high-granularity clinical data from patients undergoing elective arthroscopic shoulder and knee surgeries. The study will construct a structured registry that integrates highly detailed intraoperative objective assessments with standardized Patient-Reported Outcome Measures (PROMs). The primary objective is to evaluate the mid-to-long-term functional outcomes and utilize multivariable regression models to identify independent predictive factors for success or sub-optimal recovery. Additionally, the study involves the ethical collection of discarded intraoperative tissues (e.g., synovial fluid, degenerative tendon/cartilage fragments) and residual routine blood samples. This will establish a biobank to support future "clinical-basic" translational research exploring the microenvironment of tissue healing. By establishing this comprehensive real-world database, the investigators aim to provide robust evidence to help resolve ongoing clinical controversies in sports medicine and ultimately optimize personalized surgical and rehabilitation protocols.
