Hi, thanks for writing to HCM.
The main part of the physiotherapy
program for patellofemoral pain involves the Quadriceps muscle strengthening exercises.
You not supposed to involve in any Impact sports and deep knee bending activities as these will aggravate your pain.
Generally, upto 60% of the patients with patellofemoral pain will benefit from Physiotherapy. If physiotherapy is not going to help you, based on the amount of involvement of the articular surfaces, you may need some form of surgical intervention which will be decided by your treating surgeon.
Hope this information is helpful. Good day
