If you have had chronic knee pain than you need to get an X ray and see how bad your bone degeneration is.   With todays technology having knee surgery may be your best option. Did you know that most knee problems are coming from your tight hips?!   Except for ligament sprains, most knee pain is coming from the tight hip muscles that cross over your knee joint. These tight muscles are either compressing the bones to squish your meniscus or compressing or pulling your knee cap out.  Its easy to get rid of knee pain by treating the cause-tight hips.  Long term compression causes bone degeneration that cannot be fixed.
