What is Arthroscopic Surgery?
Arthroscopic surgery is a minimally invasive surgical procedure used to diagnose and treat joint problems. The term “arthroscopy” comes from the Greek words “arthro” (joint) and “skopein” (to look), meaning “to look inside the joint.” This procedure involves making small incisions and inserting a thin, flexible tube called an arthroscope into the joint. The arthroscope is equipped with a tiny camera that displays live images on a monitor, allowing the surgeon to see inside the joint without making large incisions.
In addition to diagnosing joint conditions, arthroscopy allows the surgeon to perform a variety of treatments using specialized instruments, such as removing damaged cartilage or repairing torn ligaments.
Common Arthroscopic Procedures (Knee, Shoulder, Wrist)
Arthroscopy is commonly used to treat joint issues in various parts of the body. Some of the most frequently performed arthroscopic procedures include
Arthroscopic procedures are also commonly performed on other joints, including the ankle, hip, and elbow.

Knee Arthroscopy
- Meniscus Repair or Removal: Fixing or removing torn cartilage (meniscus) in the knee.
- ACL Reconstruction: Repairing or reconstructing a torn anterior cruciate ligament (ACL).
- Removal of Loose Bodies: Removing loose pieces of bone or cartilage that may be floating inside the knee joint.

Shoulder Arthroscopy
- Rotator Cuff Repair: Fixing a torn rotator cuff, the group of muscles and tendons that stabilize the shoulder.
- Labrum Repair: Repairing a tear in the cartilage surrounding the shoulder joint (labrum), commonly seen in shoulder dislocations.
- Impingement Relief: Removing inflamed tissue or bone spurs that may be causing shoulder impingement and pain.

Wrist Arthroscopy
- TFCC Repair: Repairing the triangular fibrocartilage complex (TFCC), which provides support to the wrist.
- Carpal Tunnel Release: Treating carpal tunnel syndrome by relieving pressure on the median nerve.
- Treatment of Wrist Fractures: Fixing fractures in the wrist bones using minimally invasive techniques.
Indications for Arthroscopy
Arthroscopy is recommended when joint problems, such as pain, swelling, or limited range of motion, cannot be fully diagnosed or treated through non-invasive methods such as imaging studies or physical therapy. Common indications for arthroscopic surgery include:
- Torn Ligaments: Such as a torn ACL in the knee or rotator cuff in the shoulder.
- Meniscal Tears: Cartilage tears in the knee, which can cause pain, swelling, and locking.
- Joint Instability: Caused by loose or damaged cartilage or ligaments.
- Cartilage Damage: Including cartilage defects or deterioration due to arthritis or injury.
- Joint Inflammation: Inflammatory conditions such as synovitis (inflammation of the joint lining).
- Loose Bodies: Small pieces of bone or cartilage that float within the joint and cause pain or restriction in movement.
- Impingement Syndrome: Bony or soft tissue impingements in the shoulder or hip that limit motion and cause pain.
- Unresolved Joint Pain: Persistent joint pain that hasn’t responded to conservative treatments like medications or physical therapy.
Arthroscopy is often used for both diagnosis and treatment, allowing the surgeon to identify the underlying problem and repair it during the same procedure.
Arthroscopic Surgery Procedure
The arthroscopic surgery procedure involves several steps, and it is typically performed on an outpatient basis under general or local anesthesia.
Step-by-Step Procedure:
- Anesthesia: The procedure begins with administering anesthesia, which could be general (the patient is asleep) or regional (only the area around the joint is numbed).
- Incisions: The surgeon makes small incisions, usually about 1 cm long, around the joint. Through these incisions, the arthroscope and surgical instruments are inserted.
- Inserting the Arthroscope: A saline solution may be injected into the joint to expand the space and provide a clearer view. The arthroscope, with its camera and light source, is then inserted through one of the incisions, allowing the surgeon to view detailed images of the joint on a monitor.
- Diagnosis and Treatment: The surgeon examines the joint for damage, such as torn cartilage, inflamed tissues, or loose bone fragments. Specialized surgical instruments are inserted through other incisions to repair or remove the damaged tissue.
- Closure: Once the procedure is complete, the arthroscope and instruments are removed, and the incisions are closed with sutures or adhesive strips. A bandage is applied to the area.
- Post-Operative Care: Patients are typically allowed to go home a few hours after the procedure, depending on their recovery from anesthesia.
Arthroscopic surgery usually takes between 30 minutes and 2 hours, depending on the complexity of the problem being treated.
Benefits of Minimally Invasive Arthroscopy
Arthroscopy offers several benefits compared to traditional open surgery, making it a preferred option for diagnosing and treating joint problems.
Key Benefits:
- Minimally Invasive: Arthroscopic surgery requires only small incisions, resulting in less tissue damage compared to open surgery.
- Faster Recovery: With smaller incisions, patients typically experience a quicker recovery, allowing them to return to daily activities sooner.
- Less Pain and Scarring: The smaller incisions and reduced tissue trauma lead to less post-operative pain and minimal scarring.
- Lower Risk of Infection: The smaller wounds reduce the risk of infections and complications compared to open surgery.
- Outpatient Procedure: Arthroscopy is often performed as an outpatient procedure, allowing patients to go home the same day.
- Accurate Diagnosis and Treatment: Arthroscopy allows the surgeon to see inside the joint in real-time, providing a more accurate diagnosis and immediate treatment of joint issues.
Arthroscopy is widely used for its efficiency, precision, and ability to speed up recovery times for patients.
Recovery After Arthroscopy
Recovery after arthroscopy is generally faster than traditional open surgery, but the recovery timeline depends on the joint being treated and the type of procedure performed.
Immediate Post-Operative Period:
- Patients are monitored in a recovery room until the effects of anesthesia wear off, and they are typically discharged on the same day.
- Pain and swelling around the joint are common, and medications are prescribed to manage discomfort.
- Patients are advised to rest, elevate the affected joint, and apply ice packs to reduce swelling.
First Few Days:
- Light activities and movements are encouraged to prevent stiffness, but patients are advised to avoid strenuous activities, heavy lifting, or putting weight on the joint.
- Bandages should be kept clean and dry, and follow-up appointments are scheduled to check on the healing process and remove sutures if necessary.
2-4 Weeks:
- During this period, most patients can resume daily activities such as walking or driving (depending on the joint). Physical therapy may be introduced to help restore strength, mobility, and flexibility in the joint.
- For more complex procedures, such as ligament repairs, recovery may take longer, and patients should closely follow their surgeon’s guidelines.
Full Recovery:
- Most patients fully recover within 6 to 8 weeks. For athletes or individuals with more extensive repairs, the recovery process may take up to 3 to 6 months before returning to high-impact activities.
- The speed of recovery also depends on the patient’s overall health, adherence to post-operative care, and rehabilitation.
Post-Surgery Rehabilitation
Post-surgery rehabilitation plays a critical role in the recovery process after arthroscopic surgery. The goal of rehabilitation is to restore full joint function, strength, and mobility while preventing complications such as stiffness or re-injury.
Key Components of Rehabilitation:
- Physical Therapy: Physical therapy typically begins within a few days after surgery. Initially, exercises focus on gentle movements to maintain range of motion in the joint. Over time, strengthening and flexibility exercises are introduced.
- Gradual Weight Bearing: If the knee, ankle, or hip was treated, patients may gradually increase weight-bearing activities as recommended by the surgeon or physical therapist.
- Strengthening Exercises: As healing progresses, physical therapists will introduce exercises to strengthen the muscles surrounding the joint, improving stability and function.
- Balance and Coordination: In some cases, especially with lower limb surgeries, balance and coordination exercises are necessary to prevent falls and improve mobility.
- Home Exercise Programs: Patients are often given exercises to perform at home to enhance their recovery and ensure long-term success.
Long-Term Care:
- Regular follow-up appointments are necessary to monitor progress and ensure proper healing.
- Returning to sports or high-impact activities should only be done after full clearance from the surgeon, usually after several months of rehabilitation.
With proper rehabilitation, most patients can return to their previous activity levels with improved joint function and reduced pain.
