Inclusion criteria
Inclusion criteria: 1. Female patients between the ages of 45 to 80 years; 2. Meet the diagnostic criteria of knee osteoarthritis (KOA), that is, meet the main complaint of "recurrent knee pain in the past 1 month" and 2 of the following conditions: X-ray in standing or weight-bearing position The radiograph shows narrowing of the joint space, subchondral bone sclerosis and/or cystic degeneration, and osteophytes on the edge of the joint; the morning stiffness is generally less than 30 minutes; the bone friction sound (feel) is occasionally felt during active activities; 3. The Kellgren-Lawrence (KL) classification of the full-length X-ray of the lower extremities in the standing position before surgery is grade IV, which meets the indications for TKA surgery; 4. The preoperative assessment of the patient's hip abductor and knee extensor strength is grade 4-5; 5. The Advance medial pivot knee prosthesis (MP) of Shanghai MicroPort Corporation was used during the operation; 6. The chief surgeon of TKA operation is the same clinician with rich clinical experience and familiar with the TKA operation process and MP prosthesis design concept; 7. Perform unilateral TKA surgery. During the TKA procedure, the treatment of the infrapatellar fat pad was excision of 1/3-2/3; no resurfacing of the patella was performed; and peripatellar denervation was performed with electrocoagulation after patelloplasty.
