Arthroscopy uses a narrow camera, called an arthroscope which is inserted through a small incision to view the inside of a joint. Fine instruments can be introduced through another incision to repair damage. Some joint pain, swelling, or locking stays unexplained after scans. A look inside can settle it. Often the problem gets repaired during the same procedure. No large incision, and no joint laid open. It is most commonly used for knee problems, but it can also treat shoulders, hips, ankles, elbows, and wrists. Not every sore joint needs it, though.
According to Dr. Sumit Badhwar, an orthopaedic surgeon in Noida, “Arthroscopy works well when there’s a clear mechanical problem inside the joint, such as a torn meniscus or a trapped fragment. Not every joint problem requires surgery. So the diagnosis should decide the procedure, never the other way round.”
Which Joints Can Arthroscopy Be Used On?
“Arthro” means joint and “scopy” means to look inside. What the camera shows decides the next step.
- Knee: Arthroscopy can treat meniscus tears and cartilage damage. ACL and PCL tears can be reconstructed. Loose fragments that make a knee catch or lock can be removed too.
- Shoulder: Rotator cuff tears, impingement, labral tears, and repeated dislocations are the common reasons. A stiff, tight capsule can be released too, if other care hasn’t helped.
- Hip: Femoroacetabular impingement and labral tears are the main conditions addressed. It’s a more demanding operation than knee arthroscopy.
- Ankle, Elbow and Wrist: Conditions include ankle impingement or instability, loose bodies in the elbow, wrist ligament tears, and ganglion cysts. Inflamed joint lining (synovitis) can also be trimmed.
Details of the procedure for each joint are on the arthroscopy treatment page.
Arthroscopy vs Arthroplasty: What Is the Difference?
Despite the similar names, they do different jobs.
Aspect | Arthroscopy | Arthroplasty |
Main aim | Look inside the joint and repair or trim tissue | Replace worn joint surfaces with an implant |
Natural joint | Kept in place | Damaged surfaces removed |
Finding the cause | Can confirm the cause of unexplained symptoms | Not used for this |
Where used | Six joints, from knee to wrist | Mainly hip and knee, sometimes shoulder |
Usually chosen for | Tears, trapped fragments, specific faults | Severe arthritis or badly worn joints |
- Scans First: Imaging usually comes before any procedure. Arthroscopy is considered when scans haven’t explained the symptoms, or when a repair is planned.
- Degenerative Knees: A major BMJ guideline strongly advises against arthroscopy for most knees affected by arthritis or wear related meniscal tears, because exercise therapy did as well in trials. That’s the main reason it isn’t recommended for these conditions.
- Locked Knees: A knee that truly can’t straighten is the usual exception, so surgery may still be weighed there.
- Arthritis Later: Arthroscopy doesn’t undo arthritis. Not a cure. If severe arthritis follows despite nonsurgical care, replacement is the definitive option.

What Is Recovery Like After Arthroscopy?
A typical arthroscopy lasts between half an hour and two hours. The return to normal life is slower, and the pace varies with the joint and the repair.
- Pain and Swelling: Stiffness and soreness are common in the first days. Pain relief, ice, and elevating the limb usually cover it.
- Early Movement: After knee, hip, or ankle work you’ll likely need crutches for a few days. And gentle movement usually begins early.
- Driving and Daily Tasks: You can drive again once an emergency stop and full steering control are possible. Stairs can feel awkward for a while.
- Warning Signs: Seek medical advice if you notice a high temperature, pain that’s getting worse, foul smelling fluid from a wound, or numbness around the joint.
Rehab decides much of the final result. Structured physiotherapy care restores movement and strength as the joint settles, so skipping sessions costs progress.
Key Takeaways: As a minimally invasive procedure, arthroscopy finds and fixes problems inside a joint through small cuts, from cartilage tears and ligament injuries to rotator cuff tears and trapped fragments. Clear mechanical faults respond to arthroscopy treatment far better than age related changes, which is why imaging and diagnosis come first. Healing takes about a week to several months, depending on the joint.
FAQ’s
Is arthroscopy a painful procedure?
You’re anaesthetised during surgery. Afterwards, expect a few days of soreness and swelling.
How long will I be off work after a knee arthroscopy?
Roughly a week to several months, depending on the surgery and your job.
What is the most serious complication after arthroscopy?
Joint infection or a blood clot. Both are uncommon.
Is it worth having a knee arthroscopy?
It can help treat a torn ligament or locked knee. Rarely for arthritis alone.
