title: Pain reduction after anteromedial displacement of the tibial tuberosity: 5-year follow-up in 21 knees with patellofomoral arthrosis.
abstract: We performed anteromedial displacement of the tibial tuberosity in 21 knees of 16 patients having patellofemoral arthrosis with lateral subluxation. The mean age of the patients was 53 (47-65) years and they were followed for 5(2-13) years. Preoperatively, all knees were painful on descending or ascending stairs; pain was relieved after operation in 20. Retropatellar crepitations disappeared in 2 of 20 knees, but retropatellar pain when squeezing the patella against the femur disappeared in 16 of 17 knees. Patellar subluxation diminished in all knees.
