Runners knee

Runner’s knee, also known as patellofemoral pain syndrome, is a common injury among runners and others who engage in activities that involve repetitive knee bending. It is characterised by pain in the front of the knee, particularly around the patella or kneecap, which worsens with activity and improves with rest.

Runner’s knee occurs due to abnormal tracking of the patella as it moves along the femoral groove. Normally, the patella rests in a shallow groove at the end of the thigh bone, and moves up and down as the knee flexes and extends. However, if the patella is not properly aligned or the muscles that control its movement are weak or imbalanced, it can rub against the femoral groove, causing irritation, inflammation, and pain.

Several factors can contribute to the development of runner’s knee. Overuse is a common cause, as repetitive knee bending can cause wear and tear on the patellofemoral joint. Weakness or tightness in the muscles around the knee, particularly the quadriceps and hamstrings, can also affect patellar tracking. Additionally, anatomical factors such as a high-riding patella or a shallow femoral groove can increase the risk of developing runner’s knee.

Treatment for runner’s knee typically involves a combination of protect, optimal loading, ice, compression and elevation (POLICE), as well as exercises to strengthen the muscles around the knee and improve patellar tracking. In some cases, bracing or taping may be recommended to help realign the patella. If conservative measures are not effective, surgery may be an option to correct the underlying mechanical issue.
