Bottom Line: A total of 149 cases were successfully followed up for 14.8 months, on average.This procedure was highly effective for patients with cartilage defects I-III but not for patients with cartilage defect IV.For PFOA patients, this procedure is effective for significantly relieving anterior knee pain, improving knee joint function and quality of life, and deferring arthritic progression.

ABSTRACT

Background: Patellofemoral osteoarthritis commonly occurs in older people, often resulting in anterior knee pain and severely reduced quality of life. The aim was to examine the effectiveness of arthroscopic patelloplasty and circumpatellar denervation for the treatment of patellofemoral osteoarthritis (PFOA).

Methods: A total of 156 PFOA patients (62 males, 94 females; ages 45-81 years, mean 66 years) treated in our department between September 2012 and March 2013 were involved in this study. Clinical manifestations included recurrent swelling and pain in the knee joint and aggravated pain upon ascending/descending stairs, squatting down, or standing up. PFOA was treated with arthroscopic patelloplasty and circumpatellar denervation. The therapeutic effects before and after surgery were statistically evaluated using Lysholm and Kujala scores. The therapeutic effects were graded by classification of the degree of cartilage defect.

Results: A total of 149 cases were successfully followed up for 14.8 months, on average. The incisions healed well, and no complications occurred. After surgery, the average Lysholm score improved from 73.29 to 80.93, and the average Kujala score improved from 68.34 to 76.48. This procedure was highly effective for patients with cartilage defects I-III but not for patients with cartilage defect IV.

Conclusions: For PFOA patients, this procedure is effective for significantly relieving anterior knee pain, improving knee joint function and quality of life, and deferring arthritic progression.

Three-dimensional fat-suppressed spoiled gradient recalled echo sequence cartilage sequence magnetic resonance imaging shows that the cartilage on the patella and groove surface degenerated (red arrow), and this degeneration was frequently complicated by slight degeneration in the menisci and tibial joints.

Figure 1: Three-dimensional fat-suppressed spoiled gradient recalled echo sequence cartilage sequence magnetic resonance imaging shows that the cartilage on the patella and groove surface degenerated (red arrow), and this degeneration was frequently complicated by slight degeneration in the menisci and tibial joints.

Mentions: A total of 156 PFOA patients (62 males, 94 females; ages 45-81 years, mean 66 years) were involved in this study. PFOA occurred on the left side in 73 patients and on the right side in 83 patients. The average medical history was 32 months (3 months to 10 years). All patients received conservative treatment that was ultimately unsuccessful. The clinical manifestations included recurrent swelling and pain in the knee joint; aggravated pain upon ascending/descending stairs, squatting down, or standing up; positive patellar grinding tests; pain mainly located at patellar edges; varying degrees of quadriceps femoris atrophy; and a sense of joint friction during activities. Knee-joint X-rays showed that the space between the patellofemoral joint was narrowed, and osteophytosis was present. Patellar axial slices showed that the patellofemoral joints degenerated, the space between patellofemoral joints was narrow, and the patella was inclined outwards.[34] T2-weight and three-dimensional-fat-suppressed spoiled gradient recalled echo sequence (3D-FS-SPGR) cartilage-sequence magnetic resonance imaging (MRI) showed that the cartilage on the patella and femoral groove joint surface had degenerated or was lost and was mainly accompanied by slight degeneration in the menisci and tibial joints [Figure 1].[567]
