A knee sprain is an injury of the ligaments, tough bands of fibrous tissue that connect the bones of the upper and lower leg at the knee joint.
Grade I/II Treatment
If you have a Grade I or Grade II knee sprain, your doctor probably will recommend that you follow the RICE rule which stands for rest the joint, ice the injured area to reduce swelling, compress the swelling with an elastic bandage and elevate the injured knee.
Your doctor may ask you to suggest that you wear a knee brace for a short period of time and that you take a nonsteroidal anti-inflammatory drug (NSAID), such as ibuprofen (Advil, Motrin and others), to relieve pain and ease swelling.
After a few days as your knee pain gradually goes away, your doctor will prescribe a rehabilitation program to strengthen the muscles around your knee. This program should help to stabilize your knee joint and prevent you from injuring it again.
If you have a Grade III knee sprain or if multiple ligaments are injured, treatment depends on the specific type of sprain:
Grade III ACL or PCL Sprain Treatment
For grade III ACL or PCL sprain treatment, your torn ligament may be reconstructed with the help of surgery. In the surgery, either a piece of your own tissue (autograft) or a piece of donor tissue (allograft) is used. Almost all knee reconstructions use camera-guided (arthroscopic) surgery.
Grade III MCL Sprain and LCL Sprain
This injury usually is treated conservatively with RICE, NSAIDs (such as ibuprofen) and physical therapy. In certain cases, surgery may be used.
Grade III LCL Sprain
In a severe LCL sprain, the torn ligament often is repaired surgically.
