What is Arthroscopy?
Arthroscopy is a minimally invasive surgical procedure that allows orthopedic surgeons to view, diagnose, and repair internal joint structures through small keyhole incisions. A high-definition camera (arthroscope) transmits live images to a monitor, guiding specialized microscopic tools to perform repairs without opening the entire joint.
Who Needs Joint Arthroscopy?
Arthroscopy is indicated when non-surgical treatments fail to resolve chronic pain, locking, catching, or instability in the knee or shoulder joints.
Key clinical indicators include:
- Knee: Meniscal tears, loose cartilage fragments, synovial inflammation, patellar maltracking, or early ligament damage.
- Shoulder: Rotator cuff tears, labral tears (Bankart/SLAP lesions), shoulder impingement, shoulder instability, or frozen shoulder.
- General: Joint locking, clicking, persistent joint effusion (fluid build-up), or unexplained joint pain.
Types of Arthroscopic Procedures
- Knee Arthroscopy: Meniscus repair or meniscectomy, synovectomy, cartilage microfracture, and removal of loose bodies.
- Shoulder Arthroscopy: Rotator cuff repair, labral repair (for recurrent dislocation), subacromial decompression, and biceps tenodesis.
- Diagnostic Arthroscopy: Direct visual investigation when non-invasive imaging (MRI) results remain inconclusive.
Benefits of Arthroscopy
- Very small incisions resulting in minimal surgical scarring.
- Less post-operative pain and significantly lower infection risk.
- Performed as a daycare or short stay procedure.
- Faster return to work, sports, and normal daily life.
What to Expect Before Surgery?
- Pre-Op Diagnostic Imaging: MRI scans and X-rays to map joint internal structure.
- Routine Medical Clearance: Blood tests, ECG, and chest X-rays.
- Pre-Op Fasting: Standard 6 to 8 hours of fasting prior to anesthesia.
Complete Procedure
- Administration of regional (spinal/nerve block) or general anesthesia.
- Making 2 to 3 tiny portal incisions (less than 1 cm each) around the joint.
- Infusing sterile saline fluid to expand the joint space and clear visibility.
- Inserting the camera (arthroscope) to inspect all joint compartments.
- Inserting specialized arthroscopic instruments through secondary portals to trim, stitch, or repair damaged tissues.
- Fluid drainage, closing portal incisions with single sutures or steristrips, and applying a soft bandage.
What to Expect During Surgery?
The procedure lasts between 30 and 75 minutes depending on the complexity of the repair. Most patients recover in daycare and return home the same day.
Arthroscopy vs Open Surgery
| Feature | Arthroscopic Surgery | Traditional Open Surgery |
|---|---|---|
| Incision Size | 2-3 keyholes (<1 cm). | Large open incision (5-15 cm). |
| Hospital Stay | Daycare / 1 Day. | 3-5 Days. |
| Tissue Trauma | Minimal muscle and tissue disruption. | Higher tissue disruption. |
| Recovery Speed | Rapid (2-4 weeks). | Prolonged (8-12 weeks). |
Success Rate and Safety
Arthroscopic procedures have high success rates (>90%) with extremely low complication rates (<1%). It is considered one of the safest modern surgical techniques.
Arthroscopy Cost Estimate
| Procedure Type | Standard Knee/Shoulder Procedure (INR) | Complex Repair with Anchors (INR) |
|---|---|---|
| Diagnostic / Loose Body Removal | ₹80,000 - ₹1,50,000 | ₹1,50,000 - ₹2,20,000 |
| Meniscus Repair / Trimming | ₹1,00,000 - ₹2,20,000 | ₹1,80,000 - ₹3,00,000 |
| Rotator Cuff / Labral Repair | ₹1,50,000 - ₹2,80,000 | ₹2,50,000 - ₹3,80,000 |
Disclaimer: Final costs depend on the number and type of implants/anchors used (suture anchors, bio-absorbable materials).
Recovery Guide & Post-Operative Care
Recovery Timeline
- Day 0-3: Rest, ice, compression, elevation (RICE); minimal weight-bearing if instructed.
- Week 1-2: Removal of stitches; starting range-of-motion physical therapy.
- Week 3-4: Resuming light sedentary work, driving, and unassisted walking.
- Month 2-3: Full strength restoration and clearance for athletic activities.
Post-Op Precautions & Care
- Keep Incisions Dry: Keep dressing clean and dry until portal sites heal completely.
- Ice Therapy: Apply ice packs for 15-20 minutes several times daily to control swelling.
- Follow Exercise Protocol: Perform joint mobility exercises regularly to prevent stiffness.
Frequently Asked Questions
Is arthroscopy a day-care procedure?⌄
Yes, many knee and shoulder arthroscopies are performed as day-care procedures, allowing patients to go home the same day.
How long does it take to recover from knee arthroscopy?⌄
For simple meniscal trimming or diagnostic arthroscopy, recovery takes 2 to 4 weeks. Complex meniscus or rotator cuff repairs may require 6 to 12 weeks.
Will I have scars after arthroscopic surgery?⌄
Scarring is minimal because portal incisions are tiny (less than 1 cm) and usually fade significantly over time.
Is knee or shoulder arthroscopy painful?⌄
Post-operative pain is usually mild to moderate and easily managed with prescribed pain relievers and ice application.
When can I shower after arthroscopy?⌄
You can shower once your surgeon confirms the portal incisions are dry and sealed, usually within 5 to 7 days post-surgery.
