Introduction to Knee Arthroscopy
Knee arthroscopy stands as a widely practiced surgical intervention utilizing an arthroscope—an instrumental tool—for diagnosing and addressing various knee-related issues. It’s deemed a safe procedure, with the majority of patients discharged on the same day of surgery.
Anatomy of the Knee
The knee joint ranks among the body’s most intricate joints, where the lower end of the femur meets the upper end of the tibia. The patella, or kneecap, rests upon a groove at the front of the femoral end, while the fibula, a bone of the lower leg, forms a joint with the tibia. Articular cartilage, a shiny, white, slippery covering, coats the articulating surfaces of these bones. Additionally, two C-shaped cartilaginous menisci act as shock absorbers, providing cushioning and stability to the knee joint.
Indications for Knee Arthroscopy
Knee injuries are diverse, prompting the need for knee arthroscopy for diagnosis and treatment. Common knee problems warranting knee arthroscopy include torn meniscus, damaged cruciate ligament, pieces of torn articular cartilage, inflamed synovial tissue, misalignment of the patella, Baker’s cyst, and certain fractures of the knee bones.
Procedure Overview
Knee arthroscopy is typically conducted under local, spinal, or general anesthesia, chosen based on individual patient factors. The surgical process involves:
- Making two or three small incisions around the knee.
- Injecting a sterile saline solution into the knee to create space and enhance visibility.
- Inserting an arthroscope through one of the incisions, equipped with a tiny video camera to provide a clear view of the knee joint.
- Assessing the internal structures to diagnose the issue.
- Performing necessary repairs using surgical instruments inserted through the incisions.
- Draining the saline from the knee joint and closing the incisions with sutures or steri-strips.
Post-Surgery Recovery
Most patients undergo same-day discharge after knee arthroscopy. Recovery duration varies based on the complexity of the procedure performed. Pain management, through prescribed medications, is essential. Crutches or knee braces might be advised, along with a rehabilitation program focusing on restoring motion and strengthening leg and knee muscles.
Risks and Complications
While knee arthroscopy is generally safe, complications are rare. Specific risks include bleeding into the knee joint, infection, knee stiffness, blood clots, or persistent knee issues. Vigilance and adherence to post-operative care protocols help mitigate these risks.
By understanding the intricacies of knee arthroscopy, patients and medical professionals can navigate the procedure with confidence, fostering optimal outcomes and swift recovery.
