(1) Open surgery (1) Combined 3-4cm incision + minimally invasive knife release, suitable for patients with C2 type with certain skin elasticity or patients with severe and extensive adhesions between nerve and contracture tissue caused by large incision surgery in other hospitals. (2) Combination of skin dilatation + 3-4cm incision + minimally invasive debridement knife, suitable for C2 patients with very poor skin elasticity. (3) Combination of 1~3cm incision and minimally invasive knife is suitable for type A, B and C patients who are unwilling to accept minimally invasive treatment due to psychological factors. (2) Minimally-invasive surgery (1) Small needle knife release surgery, suitable for patients with type A1, A2, B1, and the patient only requires partial relief of symptoms. (2) Minimally invasive orthopedic treatment (i.e. minimally invasive stripping knife release under the guidance of C-arm machine and B-ultrasound + system rehabilitation, the treatment effect is identified by domestic experts as the leading one in China!) (2) Minimally invasive orthopedic treatment (i.e. minimally invasive peel knife release under C-arm machine and ultrasound guidance + system rehabilitation, the effect of which has been identified by domestic experts as the leading one! (3) Arthroscopic plasma pneumonectomy: suitable for type A and B patients, and patients require relief of symptoms to resume normal life or partial relief of symptoms and no scarring after surgery; the operation is not complete for type C patients. Arthroscopic surgery is more than 3 times more traumatic than the minimally invasive peel-and-knife method; the operation time is at least 30 times longer (the peel-and-knife minimally invasive method knife works in the contracted tissue for only a few minutes on one side, while the arthroscope generally takes 40 minutes to 90 minutes on both sides); the scope of treating each type of patient is not as wide as the peel-and-knife minimally invasive method; the unilateral cost of arthroscopic surgery is the standard operation fee + 2,000 yuan arthroscopic use fee.
