Abstract:

BACKGROUND: Patients with medial compartment osteoarthritis of the knee often receive unicompartmental knee arthroplasty or high tibial osteotomy treatment. However, which one is the optimal choice remains controversial.

OBJECTIVE: To compare the short-term effectiveness of high tibial osteotomy and unicompartmental knee arthroplasty in the treatment of medial compartment osteoarthritis of the knee.
METHODS: Thirty-eight patients with medial compartment osteoarthritis of the knee from May 2016 to August 2017 were enrolled. Eighteen patients were treated with high tibial osteotomy, and 20 patients were treated with unicompartmental knee arthroplasty. Tegner activity score and Lysholm knee score were compared to assess the functional recovery of knee joint. The femorotibial angle was measured on X-ray, and the cartilage degeneration of each compartment was evaluated. 
RESULTS AND CONCLUSION: (1) All incision healed primarily in both groups. All patients were followed up for 1.0-2.8 years in the high tibial osteotomy group and 1.0-3.2 years in the unicompartmental knee arthroplasty group. (2) There were significant differences in the Tegner activity score, Lysholm knee score, and femorotibial angle in the two groups before and after operation, showing that both groups could improve mobility function and correct deformity (P < 0.05). There was no significant difference in all above indexes between two groups (P > 0.05). (3) These results indicate that both high tibial osteotomy and unicompartmental knee arthroplasty can achieve good short-term effectiveness for treating medial compartment osteoarthritis of the knee; however, the long-term effectiveness needs further investigation.

Key words: high tibial osteotomy, unicompartemtal knee arthroplasty, medial compartment osteoarthritis, knee joint, follow up, joint function, knee deformity, femorotibial angle
