Arthroscopy
A minimally invasive surgical technique using a pencil-thin camera and small instruments to diagnose and repair joint problems through tiny incisions.
What the word means
Arthroscopy comes from arthro—meaning joint—and scopy, meaning to look or visualize. In practice, it’s a surgical technique where the surgeon places a pencil-thin video camera (called an arthroscope) through a small incision, usually no bigger than a quarter-inch, and threads miniaturized surgical instruments through separate quarter-inch incisions called portals. The surgeon watches a live video feed on a monitor and performs repairs from inside the joint. Because everything happens through small holes rather than one large incision, arthroscopy is called “minimally invasive.”
How many incisions and where they go
Most arthroscopic procedures need 2–4 small portals. For a knee arthroscopy, portals are usually placed around the kneecap. For the shoulder, they go at the front, back, and sides. For the ankle or hip, placement depends on what needs repair. The surgeon may also irrigate the joint with sterile fluid to rinse away blood and debris so the camera can see clearly. All of this fluid drains through the portals when the procedure is done.
The most common arthroscopic repairs at OSI
- Meniscus repair — stitching a torn cartilage pad in the knee back to where it belongs.
- Rotator cuff repair — reattaching a torn tendon in the shoulder.
- Labral repair — stitching the cartilage bumper around the shoulder or hip socket.
- ACL reconstruction — rebuilding the anterior cruciate ligament in the knee.
- Loose body removal — retrieving fragments of cartilage or bone that are floating inside the joint and causing catching or locking.
- Debridement — cleaning out damaged cartilage or inflamed tissue.
Arthroscopy versus open surgery
For many problems—especially in the knee and shoulder—arthroscopy can accomplish what used to require a large incision. The trade-offs are real. Arthroscopy offers smaller scars, less soft-tissue damage, faster recovery, and often outpatient surgery with same-day discharge. The downside is that not every problem fits through a small portal. Some fractures, severe arthritis, or complex reconstructions are still better approached through a larger incision where the surgeon has more working room and better visualization. Your surgeon will explain whether arthroscopy is the right tool for your problem.
Recovery expectations
Many arthroscopic procedures are done as outpatient surgery, meaning you go home the same day. You’ll have small bandages and possibly some swelling and bruising around the portals over the next 1–2 weeks. The joint itself may feel stiff and have mild fluid buildup for a few days as the body reabsorbs the irrigation fluid. Physical therapy usually starts within days to restore range of motion and strength. Full recovery varies by the extent of repair: meniscus repairs may need 6–12 weeks of protected weight-bearing, while simple debridement lets you walk immediately.
