[0002] As the core joint of human movement, the knee joint bears enormous pressure. Its complex structure and frequent use make knee joint diseases highly prevalent. Knee surgery is an important means of treating serious knee joint diseases or injuries, such as knee replacement surgery and cruciate ligament reconstruction. However, the postoperative rehabilitation process is lengthy and crucial, directly affecting the degree of recovery of knee joint function and the patient's quality of life.

[0003] During the recovery phase after knee surgery, traction therapy is an important adjunct to promote the recovery of knee joint function. It can help correct joint deformities, reduce pain, promote articular cartilage repair, and prevent muscle atrophy. However, existing knee traction devices have many drawbacks when used for postoperative recovery. Traditional devices are usually fixed in structure, making them inconvenient to disassemble and store, and patients have poor control over them during training. At different stages of postoperative rehabilitation, patients have different needs for the force, angle, and duration of traction, and existing traction devices cannot achieve flexible and precise control.
