Aim: The purpose of this study was to compare muscle torque during isokinetic knee movements of patients after total knee arthroplasty (TKA) with a similar healthy group. Method: 43 patients were examined 3 years after primary total knee arthroplasty with an isokinetic dynamometer (Cybex 340). Torque measurements were evaluated for extension and flexion with 4 different velocities. The results were compared with a group of 43 people without knee disease. Bouth groups consist of 29 women and 14 men. The mean age was also comparable (66.4 vs. 65.8 years). Results: A mean peak torque of 65.9 Nm was measured during extension with low velocity (60 degrees/s) in the group of patients with TKA - 84.3% of the control group (p=0.079). At the highest velocity the patients produced 30.2 Nm. This was 72.8% of the control group (difference statistically significant, p=0.006). No differences were found in the Extension/Flexion ratio between the two groups. Conclusion: The deficites of knee strength in patients after TKA are more distinct in high velocities of motion.
