Recent advances have made arthroscopy an effective tool for correcting many knee problems. According to the American Orthopedic Society for Sports Medicine, more than 4 million knee arthroscopies are performed worldwide each year.
Knee arthroscopy is most commonly used for:
- Removing or repairing torn meniscal cartilage
- Reconstructing a torn anterior cruciate ligament (ACL)
- Trimming torn pieces of articular cartilage
- Removing loose fragments of bone or cartilage
- Removing inflamed synovial tissue
Recovery from knee arthroscopy is much faster than recovery from traditional open knee surgery. Unless you’ve had a ligament reconstruction, you should be able to return to most physical activities after six to eight weeks, maybe even sooner.
The anterior cruciate ligament or ACL is one of the four major ligaments within the knee that connects the femur to the tibia. Because the ACL is so weight-bearing, it is one of the most commonly injured ligaments of the knee. Some ACL injuries only require non-surgical treatment, but torn ACLs may undergo a procedure in which it is replaced by a substitute graft made of tendon.
