What this Trial Is About

This study focuses on patients diagnosed with Grade II hip osteoarthritis, a degenerative joint condition characterized by pain, reduced range of motion, muscle weakness, and functional limitations. Hip osteoarthritis is commonly assessed using the Kellgren-Lawrence (KL) classification system, with Grade II representing definite osteophyte formation with possible joint space narrowing, where conservative management is strongly recommended. Exercise therapy, particularly strengthening of the hip abductor muscles, plays a key role in improving pelvic stability, reducing pain, and enhancing functional outcomes. Clamshell exercises are widely used to activate the gluteus medius and minimus muscles, while modified clamshell exercises are designed to optimize muscle recruitment and reduce compensatory movements. A total of 54 participants with Grade II hip osteoarthritis will be included in the study and allocated into three groups. Group A will receive clamshell exercises along with conventional exercise therapy, Group B will receive modified clamshell exercises in addition to conventional exercise therapy, and Group C will receive a conventional exercise program alone. Pain intensity will be assessed using the Visual Analog Scale (VAS), which ranges from 0 to 10. Hip joint range of motion will be measured using a goniometer, and functional outcomes will be evaluated using the Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12). The aim of this study is to compare the effects of clamshell exercises, modified clamshell exercises, and conventional exercise programs to determine the most effective intervention for reducing pain, improving hip joint range of motion, and enhancing functional outcomes in patients with Grade II hip osteoarthritis.
