Tracking recovery after arthroscopic shoulder and knee surgeries
Clinical Outcomes and Associated Factors Following Arthroscopic Surgeries for Shoulder and Knee Sports Injuries: A Prospective Cohort Study
This will follow people having routine arthroscopic shoulder or knee surgery to see if patient characteristics, tear details, or surgical choices predict better recovery and function over two years.

What this trial studies
This single-center prospective cohort will follow patients scheduled for routine arthroscopic shoulder or knee procedures and collect detailed preoperative, intraoperative, and postoperative data over two years. Standardized patient-reported outcome measures and clinical assessments will be collected at baseline and multiple postoperative time points, and discarded intraoperative tissues and residual blood will be stored in a biobank. Surgeons' intraoperative choices and objective tear morphology will be recorded to allow multivariable regression analyses identifying factors linked to better or worse outcomes. The registry approach aims to link surgical technique, patient baseline characteristics, and rehabilitation patterns with mid-to-long-term functional recovery and return-to-sport rates.
Who should consider this trial
Good fit: Ideal candidates are people age 8 or older who are scheduled for elective arthroscopic shoulder or knee surgery at the study center, can give informed consent, and can attend follow-up visits.
Not a fit: Patients needing emergency surgery for severe trauma, those with severe cognitive or psychiatric impairment that prevents consent or follow-up, or those treated at other hospitals are unlikely to benefit from participating.
Why it matters
Potential benefit: If successful, the findings could help tailor surgical and rehabilitation decisions to improve functional recovery and return-to-sport rates.
How similar studies have performed: Previous observational registries using patient-reported outcomes and surgical data have identified some predictors of outcome, but variability persists and high-granularity, biobank-linked cohorts are less common.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * Age \>= 8 years. * No gender restrictions. * Definitive diagnosis of shoulder or knee sports injuries or related joint conditions. * Scheduled to undergo elective, standard-of-care surgery at the study center (procedures include but are not limited to: arthroscopic meniscus repair/meniscectomy, cartilage repair, cruciate ligament reconstruction, high tibial osteotomy \[HTO\], unicompartmental knee arthroplasty \[UKA\], arthroscopic rotator cuff repair, shoulder stabilization, and shoulder arthroplasty). * Clear consciousness, with the ability to read, understand, and communicate. * Willing and able to comply with postoperative follow-up requirements. * Voluntarily signed the written informed consent form. Exclusion Criteria: * Patients requiring emergency surgery due to acute, severe trauma (e.g., open fractures, polytrauma). * Coexisting severe neurological or psychiatric diseases, or cognitive impairment that prevents understanding of the informed consent or cooperation with follow-up. * Patients in an involuntary state (e.g., under coercion). * Refusal to sign the informed consent form or refusal to participate in the study. * Currently participating in other interventional clinical trials that may confound or affect the clinical outcomes of this study.
