If you break your kneecap, you will be in immediate pain, and probably won't be able to walk. If this happens, you need to go to a hospital asap and get an xray. If it really is broken,,,it is quite possible that you will need surgery, not always, but quite often that happens. In either case, you will be put in either an immobilizer or a cast for several weeks. When you're allowed to take whichever you have off,,,you will hardly be able to bend your leg and will probably be sent for physical therapy. You will discover that your muscles are really weak after all the time of not using them much. Trust me, breaking your kneecap is NOT what you want to do,,it is a very , very long road back to any sort of normalcy. Remember, the gangsters who offered to "break your kneecap" didn't do that because it was an easy recovery. Most people who break their kneecap, measure their life before their injury , and after their injury.
