Your doctor may prescribe medications to relieve and treat knee pain caused by gout or rheumatoid arthritis.
Your doctor might also recommend physical therapy or strengthening exercises based on the condition that is causing your pain. In some cases, you may need arch support or other shoe inserts that will shift pressure away from the side of the knee that is being affected.
Sometimes, your doctor may recommend injecting medications and other substances into the knee, such as corticosteroids, platelet-rich plasma or hyaluronic acid.
In the case that your knee pain is caused by an injury that requires surgery, your doctor may recommend:
ACL Surgery - This type of surgery involves reconstructing or repairing the ACL using a graft to replace the ligament.
MCL Repair - This surgery involves repairing the ligament and reattaching it by way of stitches, a suture anchor, bone staples or a metal screw.
Knee Arthroscopy - This treatment helps diagnose and treat problems in the knee joint by making a small incision and using a small camera to view the inside of your joint. Arthroscopy can help diagnose knee problems, such as a torn meniscus, and can repair the ligaments of the joint.
Partial or Total Knee Replacement - Depending on the extent of your injury, you may only need surgery to replace only one affected compartment of the knee or replacement of all three knee compartments.
