Abstract Objective To assess the radiographic and functional scores of patellofemoral joint following a distal tibial tuberosity open-wedge high tibial osteotomy (DTTOWHTO).Methods A total of 36 patients with varus knee osteoarthritis with patellofemoral arthritis were treated by DTT-OWHTO in our hospital，including 15 males and 21 females.The age range was (43~64) years，with an average age of (52.96±4.59)years.Changes in Iwano’s classification，medial angle of the proximal tibia (MPTA)，patellar height，lateral patellofemoral angle (LPFA)，tibial posterior slope (TPS)，the Lysholm score，Kujala score and the Western Ontario and McMaster Universities(WOMAC) were assessed.Results All patients were followed up for (23.69±4.22)months (range：15~33 months).The Iwano’s classification of patellofemoral joint was statistically significant before and after surgery (P＜0.05).The MPTA shifted from a mean (81.84±3.96)° before operation to a mean (90.57±2.53)° after operation (P＜0.05).No changes in patellar height，LPFA and TPS were observed.The Lysholm score and Kujala score increased significantly from (58.50±5.87) and (56.69±9.43) before operation to (86.39±2.14) and (72.69±5.79) after operation，respectively (P＜0.05).The WOMAC score decreased significantly from (65.19±6.48)preoperatively to (43.81±8.48)postoperatively (P＜0.05).Conclusion DTT-OWHTO maintains the preoperative patellar height，which could help prevent progression of cartilage degeneration in the patellofemoral joint after surgery，and the radiographic as well as the clinical results support the use of this technique to treat varus knee osteoarthritis with patellofemoral arthritis.
