Your knee will be painful when you start exercising, but should ease once you’ve warmed up. The pain will return after exercise and you’ll have a sore knee for 24 hours or so. You may experience a sharp knee pain when getting up from a chair, and find that the tendon is so tender that even a small amount of pressure causes a lot of pain.
Tendinopathy, or to give it its correct name patella tendinopathy, is often confused with pain in the kneecap (patella) itself. However, the pain is specifically in the kneecap tendon. It’s caused by someone repeatedly putting strain on the tendon, which can happen a lot in sport.
Tendinopathy is actually a number of tiny partial ruptures in the tendon. Your body will try to repair the ruptures, but will keep failing. This will cause anterior knee pain. Your doctor will examine your knee and arrange an ultrasound or MRI scan.
Tendinopathy is difficult to treat. You’ll need a long course of physiotherapy, lasting anything up to six months, and you may also need an injection into the knee. Keyhole surgery may also be successful. Some patients find that the pain can only be improved upon and not cured.
