ABSTRACT
Background: Chondromalacia patellae is a disorder that causes softening and degeneration of patellar cartilage, resulting in pain around the patella. It causes quadriceps muscular weakness, particularly in the vastus medialis. The aim of this study is to compare the effects of focused and eccentric contraction on chondromalacia and determine which is the most beneficial.
Methodology: RCT was done on 50 males of age 18-25 years, were randomly divided into 2 groups: 1 is concentric group and the other is eccentric group. In both groups, all the exercises were performed 4 times/week for 6 weeks; each exercise should be done for 2 sets with 10 repetitions. NPRS and WOMAC scale was used as outcome measures and the readings were noted pre- and post- intervention.
Results: The data was analyzed by JASP Software. The mean age value of eccentric group is 22.240±2.107 and concentric group is 21.880±2.205. The data shows that there is significant improvement in eccentric group in NPRS as the post-intervention mean value is 2.72 ± 0.792 while that of concentric group is 3.680 ± 0.802; the p-value is <0.001. The data coins that there is significant improvement in all the parameters of WOMAC in eccentric group as mean value is 30.640± 3.451 and of concentric value is 34.6 ± 3.594 and the p-value is <0.001.
Conclusion: Study concluded that eccentric group is more effective than concentric group for management of chondromalacia. This suggests that exercises that emphasize eccentric contraction of the quadriceps, could be valuable addition to rehabilitation programs for individuals with chondromalacia. This coins that eccentric exercises can be effective intervention and can be considered as a primary component of treatment for chondromalacia.
