Although recovery time for arthroscopic knee surgery varies depending on the extent of the damage, recovery generally takes six to eight weeks, according to the American Academy of Orthopaedic Surgeons. Patients with extensive knee damage may not fully recover and need to limit high-impact activities.
Arthroscopic knee surgery is less invasive than conventional knee surgery, and patients are usually able to go home the day of the surgery, states the American Academy of Orthopaedic Surgeons. Knee arthroscopy involves using general, local or regional anesthetic while incisions are made in the patient's knee. Immediately after the surgery, the knee is kept propped up to reduce swelling. Physical therapy begins a few days after the arthroscopy to help strengthen the joint, asserts MedicineNet.
