Clinical Trial Summary

Patellofemoral pain syndrome (PFPS), also known as runner's knee, is a common knee condition characterized by pain and discomfort in the front of the knee, specifically around the patella (kneecap) and the surrounding area.

The causes for anterior knee pain are multifactorial like overuse, muscle imbalances abnormal tracking of the patella, biomechanical issues, and improper alignment of the lower limbs. Activities that involve repetitive knee motion, such as running, jumping, squatting, or climbing stairs, can exacerbate the condition . The PFPS may cause aching pain around the front of the knee , especially when sitting for long periods, squatting, or climbing stairs, Pain worsens with activities that involve bending the knee, popping or grinding sensation in the knee and swelling or inflammation around the knee in some cases.

Clinical Trial Description

Patellofemoral pain syndrome (PFPS) leads to pain and restricted activities in athletes. There are many remedies used to tackle this problem like Physical therapy, Orthotics or shoe inserts, Patellar taping or bracing, RICE therapy, Nonsteroidal anti-inflammatory drugs (NSAIDs) and in some cases, corticosteroid injections are administered to reduce pain and inflammation. A randomized control trial will be conducted at Pakistan Sports Board Lahore through nonprobability convenience sampling technique on 38 patients which will be allocated through simple random sampling through sealed opaque enveloped into group A and group B. Group A will receive treatment with Clamshell exercises and group B will receive simple exercises for a period of six weeks. Side-lying clam exercises include lying down on one side on an exercise mat placing the head on arm and top leg/foot on lower leg/foot. Then lift the top leg towards ceiling and lower it again upto 10 to 20 times. Change sides and do 3 sets. Outcome measures such as range of motion will be measured by goniometer and pain by NPRS Scale, Visual analogue Scale and Kujala Patellofemoral pain score and the functional status will be measured with functional mobility test and physical performance testing. Patellar grind test for knee pain will also be performed at start and end to see the effectiveness of Clamshell exercise in athletes.

Data will be analyzed using SPSS software version 21. After assessing normality of data, it will be decided either parametric or non-parametric test will be used within a group or between two groups. Effectiveness of clamshell exercises will be analyzed by comparison in individuals with PFPS.The significance of this study lies in evaluating the effectiveness of clamshell exercises of hip muscles on PFP. The clamshell exercise can be beneficial for individuals with PFPS as part of a comprehensive rehabilitation program as it primarily targets the hip abductor muscles and indirectly contributes to improving knee stability and addressing muscle imbalances that can affect PFPS.

Based on the above stated literature review focusing on PFPS, its effects and remedies, we can conclude that athletes with PFPS shows signs of improvement when re-engaged in training activities. Also Clamshell exercises have wide impact to address muscles and knee problems, so there is a dire need to fill a research gap and study the impact of these exercises on PFPS with special focus on athletes facing the pain. ;
