title: [Arthroscopic patelloplasty and circumpatellar denervation for the treatment of patellofemoral osteoarthritis].
abstract: OBJECTIVE
  To investigate surgical procedure and clinical effects for the treatment of patellofemoral osteoarthritis (PFOA) with arthroscopic patelloplasty and circumpatellar denervation.
  
  
  METHODS
  Totally 156 patients with PFOA (62 males and 94 females; aged from 45 to 61 years old with an average of 52) were treated from September 2011 and March 2013. The clinical manifestations included recurrent swelling and pains on knee-joint,and aggravated pains upon going up/down-stairs, squatting-down, or standing-up. PFOAs were treated with arthroscopic patelloplasty and circumpatellar denervation. The therapeutic effects before and after surgery were evaluated by Lysholm scores and Kujala scores. The therapeutic effects were graded by classification of cartilage injury degrees.
  
  
  RESULTS
  Totally 149 cases were successfully followed up for 14.8 months. The incisions were healed well and no complication were occurred. Lysholm score was improved from 73.29 preoperatively to 80.93 postoperatively and average Kajala score from 68.34 preoperatively to 76.48 after surgery. This procedure was highly effective for patients with I - III degree cartilage injury, while not for patients with IV degree cartilage injury.
  
  
  CONCLUSIONS
  For PFOA patients, arthroscopic patelloplasty and circumpatellar denervation is effective for significantly relieving anterior knee pains, improving knee-joint functions and quality of life, and deferring arthritic procession.
