What is Medial Open-Wedge High Tibial Osteotomy May Adversely Affect the Patellofemoral Joint about?

## Purpose: To evaluate 2-stage arthroscopic findings of the patellofemoral joint before and after medial open-wedge high tibial osteotomy (hto) and verify whether the patellofemoral joint would be influenced by medial open-wedge hto. ## Methods: We prospectively reviewed 114 cases of medial open-wedge hto for the treatment of osteoarthritis with a varus knee. first-look arthroscopy was performed during hto. the mean age at the time of hto was 56.34 ± 5.4 years (range, 40-69 years). second-look arthroscopy was performed concomitantly with plate removal at an average of 26.1 ± 6.0 months (range, 21.6-32.0 months) after hto. we assessed the patellofemoral joint using the international cartilage repair society (icrs) grading system by first- and second-look arthroscopy and compared it before and after hto. postoperative anterior knee pain was also evaluated. ## Results: Compared with first-look findings, second-look arthroscopic icrs grading was changed as follows: in terms of the patella, 89 cases (78.1%) were not progressed whereas 25 cases (21.9%) were progressed. in terms of the femoral trochlea, 67 cases (58.8%) were not progressed whereas 47 cases (41.2%) were progressed. there
