To Compare the Effect of Closed Kinetic Chain and Isometric Exercises in Reducing Pain and Improving Functional Disability in Patients With Patellofemoral Pain Syndrome Associated With Knee Osteoarthritis

Comparison of the Closed Kinetic Chain and Isometric Exercise in Female Patient With Patellofemoral Pain Syndrome Associated With Knee Osteoarthritis: A Randomized Control Trial

Investigator study aims to compare the benefits of isometric exercise and closed kinetic chain exercises in strengthening programs to lessen pain along with enhance functionality in patients with PFP that are being associated with osteoarthritis and the assessment of PFP pertains to its recognition and the determination of significant therapeutic techniques. 70 Participants from the department of physiotherapy, Civil Hospital Karachi CHK and Dow University of Health Science (DIPMR) will be randomly assigned into two groups, an experimental group receiving closed kinetic chain exercise, and a control group receiving isometric exercises. The therapy will last four weeks, consisting of twelfth sessions. There will be 35 to 40 minutes in each session, Patients will be evaluated on primary outcome measure, pain intensity and functional limitation using various scales, including the numerical pain rating scale (NPRS) and Kujala/anterior knee pain scale (AKPS)

The most prevalent issue of musculoskeletal knee joint that impact is patellofemoral pain syndrome (PFPS) particularly in young adults and the elderly, causing severe discomfort behind and around the patella, making it the primary etiology for anterior knee discomfort. Patellofemoral joint may be the first compartment affected in early knee osteoarthritis. Most exercise programs designed for treating p a t e l l o f e m o r a l p a i n ( PFP) focus on strengthening the quadriceps, primarily the vastus medialis oblique (VMO). A rehabilitation program including closed kinetic chain exercises and isometric exercises may be beneficial for patients with patellofemoral pain (PFP) to improve their functional limitations and minimize pain. Closed kinetic chain exercises improve functional movement patterns, while isometric exercises are better tolerated during pain or inflammation. The effectiveness of these approaches in individuals with patellofemoral pain (PFP) associated with knee OA is unclear, but understanding their differential impacts can guide targeted rehabilitation strategies for this complex patient population.
