Fig. 9 — Mean with 95% confidence interval work output by the extending knee over different ranges of motion for bi-unicondylar arthroplasty (Bi-UKA) and total knee arthroplasty (TKA) as a percentage of the native knee work output. Data for gait (30° to 0°), stair ascent (40° to 10°), uphill slope walking (80° to 10°), sit-to-stand (100° to 0°), and full (110° to 0°) ranges of knee flexion are shown. The asterisks (*) indicate data statistically different from the native knee, and brackets indicate differences between the arthroplasties (paired t-tests p < 0.05).
