There have been many suggestions on how to treat patients with this diagnosis. One common method, focuses on decreasing the effect of the valgus force at the knee by strengthening the hip external rotators and extensors. By decreasing the valgus forces, there is theoretically less compression on the lateral side of the patellofemoral joint.
There have also been studies on strengthening the quadriceps muscles with reported success. In the study, both closed-chain and open-chain exercises were used with improvement in function and pain.
Some alternate methods that can be included in treating PFPS are taping of the patellofemoral joint and utilizing orthotics. While there has not been much evidence in using orthotics, if the patient is reporting a decrease in pain with use, it would not hurt for them to keep using the device. Taping, on the other hand, has shown to have success in improving pain and function when combined with exercise. The study looked at here utilized a program with 2 initial weeks of taping followed by exercise that had successful long-term outcomes.
A final study we looked at was exercise vs. exercise and knee arthroscopy. Both immediate and 5-year follow-up reported improvements in pain and function; however, there was no significant difference between the two groups, suggesting that surgery may not be necessary for all individuals.
From reviewing these articles, we like to try and take a conservative approach initially with patients of PFPS by including taping, exercises that strengthen the quads and hip external rotators/extensors, and possibly orthotics. Of course, consider using additional exercises and stretches with these patients, but surgery may not be the option for everyone. Check out the articles to decide for yourselves!
