Arthroscopic knee surgery has revolutionized the treatment of anterior cruciate ligament (ACL) injuries. This minimally invasive technique allows surgeons to repair or reconstruct a torn ACL with smaller incisions and faster recovery times compared to traditional open surgery.
During arthroscopic ACL surgery, the surgeon makes small incisions around the knee and inserts a tiny camera called an arthroscope. This provides a clear view of the inside of the joint on a monitor, allowing the surgeon to assess the damage and perform the necessary repairs.
For ACL reconstruction, the surgeon will:
Remove the torn ligament
Harvest a graft (usually from the patient’s own tissue)
Create tunnels in the femur and tibia
Position and secure the graft to replace the torn ACL
Arthroscopic techniques offer several advantages over traditional open surgery:
• Smaller incisions
• Less tissue damage
• Reduced pain and scarring
• Faster recovery and return to activities
• Lower risk of complications
While arthroscopic techniques are highly effective for most ACL injuries, not all cases are suitable for this approach. Factors that may influence the decision include:
• The extent and location of the tear
• Associated injuries to other knee structures
• The patient’s age and activity level
• The surgeon’s expertise and preference
Recovery from arthroscopic ACL surgery typically involves:
• Initial rest and ice application
• Gradual weight-bearing with crutches
• Physical therapy to regain strength and range of motion
• Progressive return to sports and activities (usually 6-9 months post-surgery)
Recent developments in arthroscopic techniques have expanded treatment options for ACL injuries:
• All-inside ACL reconstruction: Uses smaller incisions and specialized instruments
• Bridge-enhanced ACL repair: Combines primary repair with a collagen-based scaffold
• Remnant-preserving techniques: Aim to maintain some of the original ACL tissue
These innovations may offer improved outcomes and faster recovery for certain patients.
