Anterior Cruciate Ligament (ACL)
The ACL crosses from back of the femur to the front of the tibia. It acts as a strong support for your knee. But the ACL can be injured if you twist your knee too far or change direction too quickly.
Repeated movement or pressure can cause the bursa around the knee to become inflamed. This is called bursitis. It happens most often to the bursa on the inner side of the knee or below the kneecap. Bursitis can limit your movement. It can also cause tenderness or swelling.
Possible treatments include:
- Resting the knee by limiting activity and avoiding direct pressure on it.
- Aspiration to remove excess fluid.
- Physical therapy and medicine to reduce pain and swelling. Some medicines are taken by mouth. Others (steroids) may be injected into the bursae.
- Splints and support bandages to improve comfort and allow the bursa to heal.
- Surgery to remove the inflamed bursa. This is rarely needed.
