Fig. 5 — Mean with 95% confidence interval work output by the extending knee over different ranges of motion for the different arthroplasty procedures as a percentage of the native knee work output. Top row: medial unicompartmental knee arthroplasty (UKA-M), medial bicompartmental arthroplasty (BCA-M), and total knee arthroplasty (TKA). Bottom row: lateral unicompartmental knee arthroplasty (UKA-L), lateral bicompartmental knee arthroplasty (BCA-L), and TKA. 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).
