10. Dislocations
This knee pain cause was previously mentioned in mechanical problems, but it truly warrants its own section. Dislocations can be partial or complete, may or may not involve the kneecap, and almost always involves tearing of ligaments (14).
Dislocation occurs when one or both of the lower leg bones move out of place in relation to the femur. Knee swelling and pain are instant and severe.
You must seek medical attention for a knee dislocation immediately or you risk losing the limb (or your life).
11. Bone Tumors
Tumors of the bone are rare, but the knee joint is the most common place for them to occur. Luckily, most bone tumors are benign – meaning they aren’t cancerous and won’t spread (15).
However, the development and removal of a bone tumor almost always causes permanent damage. Most often, the tumors lead to weakening and fractures of the knee bones (16). Surgical removal is necessary and may require a partial or full knee replacement.
Once you know the cause of your knee pain, you can make a plan to treat it and prevent it from happening again. Knee pain relief can be achieved through proper rest, rehabilitation, strength and flexibility training, and (last resort) medical interventions. If caught early, most knee pain can be treated with home remedies.
To avoid knee pain, try to get ahead of things with proper diet and exercise, maintaining a healthy weight, and regular strength and flexibility training.
Make sure to get help from a trainer if you hit the gym to avoid injury. It’s never too late for preventative measures!
