Abstract:

Objective

The purpose of this study was to compare the arthroscopy combined with high tibial osteotomy and unicompartmental knee arthroplasty for single compartmental knee osteoarthritis.

Methods

Fifty-four patients with knee osteoarthritis treated with high tibial osteotomy and unicompartmental knee arthroplasty were reviewed in our hospital between June 2020 and December 2021. Demographics, surgical data, postoperative complications, and functional outcomes were assessed, and followed up and clinical evaluation at 1, 3, 6, and 12 months before and after surgery.

Results

29 patients in the osteotomy group were followed up for a period of (1.2±0.3) years. There were 10 males and 19 females with an average age of (59.4±4.2) years. 25 patients in the UKA group were followed up for a period of (1.1±0.3) years. There were 9 males and 16 females with an average age of (58.9±5.1) years. The average femorotibial angle in the osteotomy group was significantly better than that in UKA group (175.45±1.27 vs 168.64±0.76°, P<0.01). Demographics, surgical data, and other prognostic parameters were comparative between the two groups.

Conclusions

Both arthroscopies combined with high tibial osteotomy and unicompartmental knee arthroplasty were effective methods for single compartmental knee osteoarthritis, and patients with arthroscopy combined with high tibial osteotomy observed better limb alignment than that in patients with unicompartmental knee arthroplasty.
