Joint replacement surgeries for patients with severe hemophilia, severe uremia, diabetes, severe cardiopulmonary insufficiency, immune system dysfunction, and post-bone marrow transplant for leukemia, once considered too risky by others, have become routine procedures in this department. **Scope of Diagnosis and Treatment:** Patients requiring artificial joint replacement for various diseases; joint swelling, pain, and instability from various causes; septic arthritis, joint tuberculosis, gout; femoral head necrosis, osteoarthritis of the hip and knee, rheumatoid arthritis, ankylosing spondylitis, osteoporotic pathological fractures, hemophilic arthritis, etc. **Sports Medicine** This is another rapidly developing subspecialty. The department is one of the earliest in China to perform arthroscopic surgery and is equipped with internationally advanced minimally invasive diagnostic and therapeutic instruments and rehabilitation equipment. It has successively carried out arthroscopic minimally invasive surgeries for the knee, hip, ankle, shoulder, elbow, and wrist joints to treat various types of joint pathologies and sports injuries such as meniscal tears, anterior and posterior cruciate ligament injuries, and rotator cuff tears. The department introduced the concept of sports medicine early on, focusing on bone and joint pathologies throughout the body and dedicating itself to the minimally invasive treatment of various bone and joint diseases. The attending physicians are highly experienced and have all studied and exchanged at advanced domestic and international sports medicine centers. The department emphasizes comprehensive treatment for patients with sports injuries, combining meticulous surgery with systematic, standardized rehabilitation exercises to promote better recovery, achieving a high patient satisfaction rate. **Scope of Diagnosis and Treatment:** Minimally invasive treatment of shoulder, elbow, wrist, hip, knee, and ankle joint diseases; arthroscopic treatment of synovitis, osteoarthritis, gouty arthritis, and pigmented villonodular synovitis; arthroscopic minimally invasive repair of knee cartilage and meniscus injuries; arthroscopic minimally invasive reconstruction of knee collateral and cruciate ligament injuries; arthroscopic repair of recurrent shoulder dislocation (labral repair) and rotator cuff repair; elbow osteoarthritis; minimally invasive treatment of hip synovial chondromatosis, hip labral tears, and femoroacetabular impingement syndrome. **Bone and Soft Tissue Tumor Surgery** The department is one of the national centers for the diagnosis and treatment of bone and soft tissue tumors.

It is at an advanced domestic level in limb-salvage surgery for malignant bone tumors of the extremities, surgical treatment of pelvic tumors, soft tissue tumors, and giant tumors, comprehensive treatment of bone metastases, and high-dose chemotherapy for malignant tumors. In 1997, a successful case of treating a malignant iliac bone tumor using the "de-boning and tumor-killing" technique was widely reported by domestic and international media. Integrating modern oncological trends, the department has developed a comprehensive set of treatment strategies for bone tumors. Based on the malignancy grade and tumor staging, advanced techniques such as neoadjuvant chemotherapy, radiotherapy, and biotherapy are employed, significantly improving the postoperative survival rate for patients with malignant bone tumors. **Scope of Diagnosis and Treatment:** Various primary benign and malignant bone and soft tissue tumors, various tumor-like lesions, bone and soft tissue metastases, such as: osteochondroma, lipoma, hemangioma, ischial bursitis, enchondroma, giant cell tumor of bone, fibrous dysplasia, eosinophilic granuloma, osteosarcoma, Ewing's sarcoma, malignant fibrous histiocytoma, etc. **Pediatric and Adult Orthopedic Surgery** This is an independent specialty covering a wide range of diseases.
