Arthroscopy is a minimally invasive surgical procedure used to diagnose and treat conditions affecting the joints. Instead of making large incisions, the surgeon inserts a thin camera called an arthroscope through small incisions around the joint. This allows them to view the internal structures on a high-definition screen and perform precise treatment through additional tiny incisions.

Because the approach is less invasive than traditional open surgery, arthroscopy typically results in faster recovery, smaller scars and less postoperative discomfort. It is commonly performed on the knee, shoulder, ankle and wrist, where many injuries involve soft tissue, cartilage and ligament structures that are best visualised with a specialised camera.

The treatment is often recommended when symptoms persist despite conservative care or when imaging suggests injuries that require repair.

How does Arthroscopy work?

One of the key elements of arthroscopy is that it allows the surgeon to look inside the joint and address the problem simultaneously. It generally involves the following steps:

Arthroscopy vs. Open Surgery

Here’s a clear comparison between arthroscopy and open orthopaedic surgery to highlight how each approach differs in technique, recovery and clinical use.

Benefits of Arthroscopy

Arthroscopy offers several advantages over traditional open surgery, such as:

• Allows the doctor to treat multiple issues within the same joint within one session
• Faster recovery and earlier return to daily activities or sports
• Less postoperative pain due to reduced tissue disruption
• Lower risk of infection compared to open procedures
• More accurate diagnosis with direct visualisation of internal joint structures
• Smaller incisions that lead to minimal scarring

What conditions can Arthroscopy treat?

The procedure can address a wide range of joint injuries and degenerative problems. Some of the common conditions that may benefit from this treatment include:

Knee conditions

• ACL or ligament injuries – torn ligaments may be reconstructed through small incisions to restore knee stability.
• Cartilage damage – rough or worn cartilage can be smoothed, repaired or stimulated to heal.
• Loose bodies – fragments of bone or cartilage can be removed to reduce catching or locking.
• Meniscus tears – torn knee cartilage can cause locking, clicking or pain; arthroscopy trims or repairs the damaged tissue.
• Patellar tracking problems – minimally invasive techniques help restore proper kneecap movement.
• Synovitis – inflamed joint lining may be cleaned out to relieve pain and swelling.

Shoulder conditions

• Frozen shoulder (in selected cases) – tight tissue may be released if stiffness is severe.
• Labral tears (Bankart or SLAP) – cartilage rings around the socket can be repaired to improve stability.
• Recurrent dislocations – stabilisation procedures help prevent future dislocations.
• Rotator cuff tears – damaged tendons can be repaired arthroscopically to restore lifting and overhead movement.
• Shoulder impingement – bone spurs or inflamed tissue can be removed to relieve pinching pain.

Ankle conditions

• Ankle impingement – overgrown tissue or bone spurs are removed to improve motion.
• Cartilage injuries (osteochondral lesions) – damaged cartilage and bone can be cleaned and stimulated to heal.
• Ligament injuries – damaged ligaments can be repaired to prevent chronic instability.
• Loose fragments – debris can be removed to reduce pain and mechanical symptoms.

Wrist conditions

• Cartilage wear or chondromalacia – damaged surfaces can be smoothed to ease discomfort.
• Ganglion cysts – selected cysts can be addressed minimally invasively.
• TFCC tears – the triangular fibrocartilage complex (TFCC), which stabilises the wrist, can be repaired arthroscopically.
• Wrist ligament injuries – partial tears may be repaired to improve grip and stability.

Who is a good candidate for Arthroscopy?

While the treatment is minimally invasive, not everyone will benefit equally. Arthroscopy is most effective for patients whose symptoms arise from specific, repairable problems inside the joint. This includes:

Factors of a good candidate

• Symptoms caused by mechanical problems – patients who experience catching, locking, clicking or sharp pain during movement often have structural issues such as torn cartilage or loose fragments. These problems are frequently treatable through arthroscopy.

• Localised injuries confirmed on imaging – magnetic resonance imaging (MRI) or X-ray findings such as meniscal tears (knee), labral tears (shoulder), ligament injuries (ankle) or cartilage defects (wrist) indicate a targeted problem that arthroscopy can address directly.

• Persistent symptoms despite conservative care – when rest, medication, activity modification or physiotherapy fail to relieve pain, a minimally invasive procedure may help restore mobility and comfort.

• Good baseline joint health – arthroscopy works best when there is only mild to moderate wear. Patients with preserved joint space and stable alignment typically achieve better outcomes.

• Aimed at restoring function for active individuals – athletes or physically active patients with sports-related injuries often benefit from arthroscopic repair to prevent long-term instability and return safely to their routines.

• Medically suitable for day surgery – most arthroscopic procedures are performed as day surgeries. Stable medical conditions and good general fitness make the procedure safer and recovery smoother.

• Willingness to commit to rehabilitation – although minimally invasive, recovery still requires physiotherapy. Patients who engage consistently with strengthening and mobility exercises usually regain full function faster.

Factors that make someone less suitable

• Advanced osteoarthritis – when the entire joint is worn out, arthroscopy provides limited benefit. In these cases, non-surgical management or joint replacement may be more appropriate.

• Unstable or severely deformed joints – significant misalignment, longstanding instability or extensive ligament damage may require reconstructive surgery rather than arthroscopy alone.

• Uncontrolled medical conditions – conditions such as poorly managed diabetes, heart disease or bleeding disorders increase the risk of complications and may delay surgery.

• Active infection or skin wounds around the joint – any infection must be treated before surgery to reduce the risk of spreading bacteria into the joint.

• Extensive cartilage loss – If the cartilage is severely thinned or absent, removing loose tissue through arthroscopy may not improve symptoms in a meaningful way.

• Unclear source of pain – arthroscopy is most successful when the problem is clearly identified. If imaging does not match symptoms, other assessments may be needed first.

What to expect during Arthroscopy?

Once arthroscopy is recommended, the process is straightforward and typically carried out as a day procedure. Each step is designed to give your surgeon clear access to the joint while keeping the experience smooth and predictable for you.

The procedure consists of:

• Before the procedure – you will have a detailed consultation to review your symptoms, imaging results and treatment goals. Our doctor will explain what the camera can address, what may improve and any limitations based on your joint condition. This is also when medication adjustments and pre-surgery instructions are confirmed.

• On the day itself – you will be checked in by the nursing team and prepared for surgery. The surgical area is marked and simple safety checks are completed. Most patients receive either regional anaesthesia or a short general anaesthetic, depending on the joint involved.

• During arthroscopy – small incisions are created around the joint, allowing a thin camera (arthroscope) to enter. The joint is filled with fluid to create space and improve visibility. Through another small portal, the surgeon inserts instruments to repair tissue, remove debris, smooth cartilage or treat inflammation. Because the image is magnified on a screen, even fine details can be addressed with precision.

• Immediately after – you will rest briefly in the recovery area while your vital signs are monitored. A dressing is applied over the small incisions and the limb may be supported in a sling, splint or bandage depending on the joint treated.

• Post-treatment rehabilitation – most patients can start gentle movement soon after the procedure. The aim is to prevent stiffness without straining the healing tissues. You will receive clear instructions before going home.

Aftercare and recovery after Arthroscopy

Recovery varies from person to person, but most individuals settle into their routine fairly quickly with the right guidance. Even though the incisions are small, the joint itself needs time to settle and respond to treatment.

That is why it is important to adhere to the following guidelines:

• Resting wisely – avoid heavy or jerky movements during the first few days. Supportive devices like slings or crutches may be recommended temporarily to reduce pressure on the healing joint.

• Reducing discomfort – mild pain and swelling are common. Ice packs, elevation and prescribed medication help manage these symptoms. The joint generally feels more comfortable once inflammation settles over the first week or two.

• Starting physiotherapy – rehabilitation begins early. Initial sessions focus on regaining flexibility, followed by strengthening and control work. Each programme is individualised because knee, shoulder, ankle and wrist injuries behave differently during recovery.

• Returning to activity – most people return to office work within a few days and resume light daily tasks quickly. Sports, overhead activity and high-impact loading may take several weeks to months, depending on the procedure performed.

• Follow-up – review appointments help monitor your progress and wound healing. Your physiotherapy plan may be adjusted based on your range of motion, swelling and strength.

• Red flags – seek medical help if you notice increasing warmth, spreading redness, persistent fever, sudden swelling or worsening pain.

What results can you expect?

Most patients notice gradual improvement as swelling decreases and mobility returns. Arthroscopy often provides meaningful relief because it directly addresses the structure that irritates. Once the joint settles, many people find they can move more easily, perform daily tasks without discomfort and return to activities they previously avoided.

Outcomes differ depending on the severity of the original injury, the type of repair performed and adherence to the rehabilitation plan. But in general, improvements continue steadily over weeks to months.

How many sessions are needed?

Arthroscopy itself is a single procedure, but recovery involves planned reviews and rehabilitation:

• Wound review – 1 to 2 weeks after surgery
• Rehabilitation – regular physiotherapy over 4 to 12 weeks
• Progress reviews – every 1 to 3 months as needed
• Long-term checks – only if required for complex repairs or lingering symptoms

Some patients progress quickly, while others need extra time if stiffness, swelling or weakness were present before the procedure.

Summary

The surgical procedure is a minimally invasive alternative to diagnose and treat joint problems involving the knee, shoulder, ankle or wrist. By using a camera and fine instruments through small incisions, it offers targeted treatment with shorter downtime, less discomfort and faster return to activity. Many patients experience better movement, reduced pain and improved confidence once the joint heals and rehabilitation is complete.
