Abstract

Background
Knee osteoarthritis (OA) occurs frequently in females. So far, no study has evaluated postoperative outcome measures in females based on body height. We aimed to evaluate postoperative pain relief and Knee Injury and Osteoarthritis Outcome Score (KOOS) at 6 months in women following total knee arthroplasty (TKA).
Results
The baseline demographics, KOOS, waist-hip ratio, and knee range of motion were similar. The height mean ± standard deviation (SD) (range) in Group I was 149.85 ± 3.28 (142.5–152.5) cm versus 157.25 ± 2.99 (155–165) cm in Group II, = 0.001. KOOS score improved in patients of both Groups I and II as compared to the respective baseline. At 6 months, the KOOS pain score improved to 96.50 ± 3.14 [94.26–98.74 (89–100)] in Group I as compared to 89.40 ± 6.45 [84.79–94.01 (81–100)] in Group II, value = 0.02.
Conclusions
Postoperative KOOS pain score at 6 months was superior in short stature versus normal stature women following TKA surgery.
