A Progressive Strength Training Program Starting 3 Months Post Total Knee Arthroplasty Surgery Improves Strength but Not Functional Outcome

1.1. Background: Decreased quadriceps and hamstring strength is common even one year after a total knee arthroplasty. Hence, patients with persistent functional complaints treated at the Maastricht University Medical Centre (MUMC+) received a progressive strength training program.
1.2. Objectives: The aim of this study was to investigate the impact of the progressive strength training program on quadriceps and hamstring strength.
1.3. Methods: Patients were referred to the outpatient physical therapy department of MUMC+ and received a 6-week progressive strength training program. Their isokinetic quadriceps and hamstring strength and functional ability were assessed before and after the program.
1.4. Results: Men significantly improved in terms of all strength parameters assessed at an angular velocity of 60°/sec and 180°/sec. Women only improved their quadriceps strength at 180°/sec. No significant improvement at functional level was seen.
1.5. Conclusion: A 6-week progressive strength training program has a positive impact on the isokinetic quadriceps and hamstring strength in both men and women, but not on functional ability.
1.6. Level of Evidence: Level 3.
