A member asked:
Knee cracking pain only going upstairs, knee collapsed , crunching sounds, lack of extension patella not tracking as per physio what is the cause?
A doctor has provided 1 answer
Patellofemoral issue: The likely cause of your condition is that the knee cap is getting off track when you bend your knee due to lack of quad muscle strength (VMO). This causes the knee cap to track laterally when you bend your knee and leads to cartilage irritation (chondromalacia) under the knee cap which can cause aching and produce crunching sounds. Keep working with your physio to correct the problem.
