Although arthroscopic surgery is a minimally invasive and highly effective procedure, it is not always possible to see immediate results. Arthroscopic surgery is also not a one-and-done procedure. Different patients respond differently to arthroscopic surgery, with some patients experiencing immediate relief and others experiencing worsening symptoms. Many factors are involved, and only with a thorough understanding of these factors is it possible to predict the outcome of arthroscopic surgery and successfully guide patients through their recovery. The evolution of the disease after arthroscopic surgery is generally divided into three phases: the reactive synovitis phase, the periarticular aseptic inflammation phase, and the functional rehabilitation phase. The different stages have correspondingly different rehabilitation therapies. The advanced nature of minimally invasive joint surgery is reflected in the small incision, precise operation, mild pain and quick recovery. However, this does not mean that patients can return to normal after surgery by simply resting in bed. Only the correct implementation of postoperative rehabilitation can ensure good results of surgical treatment. Early postoperative rehabilitation can reduce postoperative joint edema, pain, prevent muscle atrophy and joint tissue adhesions in the affected limbs. Of course, insisting on rehabilitation training after surgery, timely contact with rehabilitation physicians and therapists, and timely revision of rehabilitation treatment plans can greatly shorten the recovery time of postoperative patients and ensure complete functional recovery.
