Knee pain which occurs without a specific known cause is labelled “Idiopathic Knee Pain”. Often, poor biomechanics or muscle imbalances can lead to affecting structures around the knee to cause pain. Knee pain can also be produced by referred pain from other areas of the body such as your lumbar spine or your hip.
Physiotherapists are trained to identify where the pain is coming from and what sort of biomechanical issues are causing those structures to be compromised. Treatments will likely involve strength exercise program to help fix the biomechanical issues. Treatment methods such as manual therapy and massage as well as taping also help to get the patients to effectively complete their exercises.
