Procedure
Elbow arthroscopy
Keyhole surgery of the elbow joint, performed through several small portal incisions using a camera and specialised instruments. Used to treat loose bodies, arthritic spurs, capsular contractures, and other intra-articular pathology with less soft-tissue trauma than open elbow surgery.
Indications
When elbow arthroscopy is the right operation
Elbow arthroscopy is used to treat a range of intra-articular problems where keyhole access offers a real advantage over open surgery. Common indications include:
- Loose body removal. Free fragments of bone or cartilage in the joint cause catching, locking, and intermittent pain. Arthroscopy gives clean access to all compartments of the elbow joint and allows removal under direct vision.
- Debridement for impingement. Bony spurs (osteophytes) at the front and back of the elbow develop in early arthritis or after old trauma. They block full extension or full flexion and cause mechanical pain at the end of motion. Trimming these spurs back to a clear path restores movement.
- Capsular release for stiffness. A thickened, scarred joint capsule after trauma or surgery limits flexion or extension. Arthroscopic release of the contracted capsule, combined with structured rehabilitation, gains range of motion.
- Osteochondral lesions. Localised damage to the cartilage and underlying bone, often on the capitellum in young throwers and gymnasts. Treatment ranges from debridement and microfracture to fragment fixation depending on the size and stability of the lesion.
- Synovectomy. Removal of inflamed or proliferative synovial lining in inflammatory arthritis or pigmented villonodular synovitis.
- Arthroscopic ECRB release. For resistant tennis elbow, the diseased ECRB origin can be released arthroscopically with the advantage of inspecting the intra-articular structures at the same time. See the tennis elbow surgery page for the full indication.
- Diagnostic arthroscopy. Occasionally indicated when imaging has not identified the source of mechanical pain or locking, and a direct look inside the joint will inform definitive treatment.
How it works
Why keyhole access works for the elbow
The elbow is a complex hinge joint with three articulations packed into a small space: the humeroulnar, the humeroradial, and the proximal radioulnar joints. The joint capsule is relatively thin, and the major nerves of the upper limb run close by, particularly the ulnar nerve at the medial side, the radial and posterior interosseous nerves on the lateral side, and the median nerve at the front.
Arthroscopy gives a magnified, well-lit view of all three articulations and the joint recesses without the soft-tissue dissection that open elbow surgery requires. The joint is gently distended with sterile fluid, which protects the capsule and pushes the surrounding nerves a few millimetres away from the working portals.
Because the working space is tight and the nerves are close, elbow arthroscopy is technically more demanding than shoulder or knee arthroscopy. Consistent portal placement, careful instrument handling, and full familiarity with the cross-sectional anatomy are what keep the procedure safe.
The procedure
What happens in the operating theatre
Elbow arthroscopy is performed under general anaesthetic, often with a regional nerve block to help with pain control after surgery. The patient is positioned either supine with the arm suspended, lateral, or prone with the arm over a bolster, depending on the planned procedure and surgeon preference.
The bony landmarks are marked. The joint is distended with sterile fluid through a needle, which creates working space and pushes the neurovascular structures away from the planned portals. A small portal is made for the camera, and additional working portals are made under direct vision as needed.
The whole elbow joint is systematically inspected. The pathology identified is then treated through the working portals: loose bodies are extracted, spurs are trimmed, contractured capsule is released, and synovitis is shaved down. The joint is then irrigated to remove debris.
The portals are closed with absorbable sutures. A bulky dressing and a sling are applied. Most cases are a day case; more extensive procedures may stay overnight.
Recovery
What recovery looks like
Recovery depends on what was done inside the joint. The general pattern is a sling for comfort for a few days, with early supervised range of motion starting within the first few days. For most procedures the small portal wounds heal quickly and there is no specific protection needed for the joint.
For loose body removal or simple debridement, most patients are back to office work within one to two weeks and to full activity within four to six weeks. For arthroscopic capsular release, the first six weeks are critical: structured physiotherapy with home exercises and continuous passive motion (in some cases) is essential to maintain the range of motion gained at surgery. For osteochondral procedures and more extensive work, recovery is longer and follows the specific protocol for the procedure done.
Driving is usually possible within one to two weeks for simple procedures, longer for more complex work. Manual work and sport are guided by the specific procedure and the demands of the activity.
Complications and risks
What can go wrong
Elbow arthroscopy is generally safe in experienced hands, but the proximity of major nerves to the working area means the specific risks are taken seriously and discussed in detail at consultation:
- Nerve injury. The principal specific risk. The ulnar, median, radial, and posterior interosseous nerves all run close to the joint capsule. Most reported injuries are temporary neuropraxia from stretch or local fluid pressure rather than direct nerve injury, and the majority recover. Permanent injury is rare.
- Stiffness. A period of stiffness after capsular release is expected and managed with physiotherapy. Recurrent stiffness after release is the principal long-term concern and depends on the underlying pathology and rehabilitation compliance.
- Recurrent symptoms. For arthritic debridement, the relief is symptomatic rather than disease-modifying. Spurs and loose bodies can re-form in advanced arthritis and may require further treatment.
- Infection. Uncommon. Antibiotics are given at induction.
- Persistent portal pain. A small number of patients have lingering tenderness at one of the portal sites. Almost always settles by three months.
- Complex regional pain syndrome (CRPS). A rare condition that causes pain and stiffness in the hand.
- Anaesthetic and medical complications. Discussed separately by the anaesthetist before surgery. The risk of DVT is low for upper-limb surgery.
FAQ
Frequently asked questions
- What is elbow arthroscopy used for?
- Elbow arthroscopy is used for loose body removal, debridement of arthritic spurs causing impingement and locking, capsular release for the stiff post-traumatic elbow, treatment of osteochondral lesions, synovectomy in inflammatory arthritis, and arthroscopic ECRB release for resistant tennis elbow. Occasionally diagnostic arthroscopy is performed when imaging has not identified the source of mechanical symptoms.
- How is elbow arthroscopy different from shoulder or knee arthroscopy?
- The principles are the same, but the elbow is technically more demanding. The joint is small, the working space is tight, and the major nerves of the upper limb (median, ulnar, radial, and the posterior interosseous branch) all run close to the joint capsule. Portal placement, distension, and instrument handling have to be careful and consistent to keep those structures safe. Elbow arthroscopy is generally regarded as the most technically challenging of the common arthroscopic procedures.
- What does recovery look like?
- Recovery depends on what was done inside the joint. For loose body removal or simple debridement, recovery is rapid and most patients are back to office work within one to two weeks and to full activity within four to six weeks. For capsular release, structured early supervised motion is essential to maintain the range gained at surgery. For osteochondral procedures and more extensive work, recovery is longer.
- How effective is elbow arthroscopy for stiffness?
- Arthroscopic capsular release for the stiff post-traumatic elbow is effective at gaining range of motion in the operating theatre. The challenge is maintaining that range during recovery. The first six weeks after surgery are critical and need close physiotherapy supervision. With a committed patient and a good rehabilitation programme, durable improvements in range and function are typical.
- Will I be left with much pain or scarring?
- Three or four small portal incisions are used, each closed with absorbable sutures. The scars become barely visible over a few months. Pain is usually well controlled with simple analgesia after the first few days. Significant ongoing pain after elbow arthroscopy is uncommon and usually relates to the underlying pathology rather than the surgery itself.
