ABSTRACT
Background: The Patrick Step Up exercise enhances knee extensor strength, particularly terminal extension. Vastus medialis oblique (VMO) muscle aids knee extension and patellar stabilization. This exercise targets quadriceps within a closed kinematic chain, crucial for post-total knee arthroplasty (TKA) rehabilitation due to post-op strength reduction.
Methodology: Ten participants were randomly assigned to two groups. Experimental: Patrick Step Up exercise. Control: Traditional VMO strengthening. Goniometry measured knee extension, KOOS assessed outcomes.
Results: ROM analysis: Group A (Patrick Step Up) showed significant ROM reduction, raising joint mobility questions. Group B also exhibited ROM reduction. KOOS: Group A had notably higher KOOS scores, aligning with exercise impact on patient-reported knee function and quality of life.
Conclusion: The study advances post-TKA exercise understanding, highlighting Patrick Step Up's potential benefits in enhancing patient-reported knee function and quality of life. Further research should explore tailored interventions for optimized rehabilitation.
