Effect of Partial Fibula Osteotomy Combined with Arthroscopic Debridement Surgery in the Treatment of Medial Compartment Knee Osteoarthritis

This study aimed to investigate the effect of partial fibula osteotomy combined with arthroscopic debridement surgery on the treatment of medial compartment knee osteoarthritis. From January 2013 to June 2016, 17 patients who suffered from medial compartment knee osteoarthritis were assigned to two groups: groups A (n = 5) and B (n = 12). Group A patients were treated with arthroscopic debridement surgery only, while group B patients received additional fibula osteotomy in addition to arthroscopic debridement operation. Visual analogue score (VAS) and hospital for special surgery (HSS) knee score were evaluated and compared between the two groups. Group B had significant reduction in the VAS after the procedure (3.1 +/- 0.8) compared with that before the procedure (6.9 +/- 1.0) or group A after surgery (5.4), respectively,p < 0.05. In contrast, the HSS knee score increased significantly in group B after the procedure (83.6 +/- 2.5) compared with that before the procedure (63.0 +/- 3.8) or group A after the surgery (68.2 +/- 2.8), respectively,p < 0.05. Partial fibula osteotomy combined with arthroscopic debridement surgery is superior to arthroscopic debridement surgery only in the treatment of medial compartment knee osteoarthritis.
