What are the advantages of ankle arthroscopy? 1. Foot and ankle arthroscopy can make more accurate judgments and treatment of articular cartilage, ligaments and intra-articular structures in the foot and ankle than open surgery; Ouyang Liu, Department of Orthopedics, Wuhan Union Hospital 2. 3. Complications of foot and ankle arthroscopy are relatively few, such as neurovascular injury, infection, joint adhesions, etc. Which diseases of the foot and ankle are suitable for ankle arthroscopy? Indications: Osteoarthritis of the foot and ankle p Osteochondral injury p Bony and soft tissue impingement syndrome of the ankle p Intra-articular free body p Intra-articular fracture p Synovitis p Early to mid-stage talar osteonecrosis p Ankle ligament injury or joint instability p Joint infection p Joint fusion p Intra-articular tumor p Unexplained swelling and pain, interlocking, etc. What problems can be solved by ankle arthroscopy? 1. Soft tissue disease can be removed using a planer. 2. Cartilage injuries can be repaired until the surface is flush and the edges are smooth. 3. Osteoarthritis is repaired arthroscopically by trimming the degenerated cartilage, removing part of the inflamed synovium, flushing the joint cavity adequately, and removing the free body if there is one. In soft tissue impingement syndrome of the ankle joint, the impinging soft tissue, bone fragments or collateral bone are removed or removed arthroscopically with a planer or clamp. 5. For early or mid-stage talar osteonecrosis, arthroscopic drilling to the lesion site can be used with some effect. In the treatment of transarticular surface fracture, arthroscopy is mainly used to monitor the neatness of the joint surface after repositioning, so that internal fixation can be done after the fracture gap disappears and the joint surface is flat, which can reduce the occurrence of arthritis. 7. Joint infection can be treated by arthroscopic cleaning and irrigation. 8. Some benign intra-articular tumors can be removed by arthroscopy and the tumor tissue can be sent for pathological examination. 9. Arthroscopy can be used to observe the morphology and tension of the ligaments and to treat combined intra-articular injuries in ligament rupture and post-rupture joint instability. How long does it take to recover after ankle arthroscopy? Recovery is faster than open surgery. After routine arthroscopic exploration and cleaning, foot and ankle flexion and extension exercises are feasible, and normal weight-bearing walking can be resumed 1 to 2 weeks after surgery.
