Procedure

Tennis elbow surgery

Surgical release and debridement of the diseased extensor carpi radialis brevis (ECRB) origin at the lateral epicondyle. Reserved for the small group of tennis elbow patients who have not improved after six months or more of comprehensive non-operative treatment.

Indications

When tennis elbow surgery is the right operation

Tennis elbow has a strong tendency to settle on its own with the right non-operative programme. The natural history is favourable over twelve to eighteen months, and almost all patients are better off pursuing non-operative treatment first. Surgery is considered when:

  • Symptoms have persisted at least six months. Some surgeons use a longer threshold of nine to twelve months, particularly in patients with mild to moderate symptoms.
  • Non-operative treatment has been thorough. Activity modification, eccentric-loading physiotherapy, a counter-force brace, and selective injection therapy. Surgery is not a shortcut around the conservative programme.
  • The pain is significantly limiting function. Difficulty with everyday gripping tasks, work duties, sport, or sleep. Mild discomfort that does not impact daily life is rarely worth operating for.
  • The diagnosis is clear. Lateral elbow pain has multiple potential causes, including radiocapitellar joint pathology, posterolateral rotatory instability, posterior interosseous nerve compression, and referred pain from the cervical spine. The decision to operate depends on confidence that the ECRB origin is the pain generator.

See the tennis elbow condition page for the full non-operative pathway and the diagnostic considerations that should be worked through before surgery is on the table.

How it works

What the surgery does to the diseased tendon

The extensor carpi radialis brevis (ECRB) is one of several tendons that share an origin on the lateral epicondyle of the humerus. In tennis elbow, the deep undersurface of the ECRB origin develops a region of tendon degeneration rather than inflammation. Histology shows disorganised collagen, increased vascularity, and fibroblastic changes consistent with chronic tendinosis.

The surgery aims to remove that diseased tissue and let healthy tendon heal back to bone. The principle is the same whether the technique is open or arthroscopic. The diseased portion of the ECRB origin is identified, excised down to healthy tissue, and the bony footprint is prepared so that healing tendon can attach cleanly. Some surgeons add a small suture repair to anchor the tendon edge back to the bone.

The recovery time is needed for the residual tendon to heal back to the prepared bony footprint. Strength returns gradually as this healing matures, typically over three to four months.

The procedure

What happens in the operating theatre

Tennis elbow surgery is performed under general anaesthetic, often with a regional nerve block to help with pain control after surgery. The patient lies supine with the arm out on an arm board, and the operative arm is prepped and draped free. The surgery is a day case.

For an open release, a small incision is made over the lateral epicondyle. The fascia is split, and the diseased portion of the ECRB origin is identified at the deep undersurface of the tendon. The degenerative tissue is excised back to healthy tendon. The bone of the lateral epicondyle is decorticated with a curette or burr to encourage a bleeding surface for healing. The tendon is repaired or left to heal to bone.

For an arthroscopic release, a camera is placed inside the elbow joint through a small portal. The capsule is opened to visualise the deep undersurface of the ECRB. A small shaver or radiofrequency probe is used to excise the diseased portion of the tendon and prepare the bony footprint. The intra- articular structures are inspected at the same time so that any associated pathology can be addressed.

The wound is closed in layers with absorbable sutures. A bulky dressing and a sling are applied at the end of the procedure.

Recovery

What recovery looks like

A sling or removable splint is worn for one to two weeks for comfort. Gentle range of motion exercises start within the first week under physiotherapy guidance, with the aim of preventing stiffness while the tendon heals.

Light functional use of the arm progresses over the first six weeks. Strengthening starts at around six weeks with light resistance, building gradually as the tendon healing matures. Heavy gripping and racquet sport are deferred until three to four months.

Most patients return to office work within one to two weeks and to driving by two to four weeks. Manual work and sport are cleared at three to four months depending on the demands of the activity. Some residual ache with heavy gripping can persist for several months and gradually settles. Strength continues to improve for up to a year.

Complications and risks

What can go wrong

Tennis elbow surgery is a small operation with generally good outcomes. The specific risks include (but are not limited to):

  • Persistent or recurrent pain. The most important consideration. A small number of patients continue to have lateral elbow pain after surgery. Causes include incomplete debridement, missed associated pathology such as radiocapitellar arthritis or PIN compression, or a pain generator other than the ECRB.
  • Stiffness. Mild loss of full extension is occasional and usually settles with physiotherapy. Significant stiffness is uncommon.
  • Infection. Uncommon. Antibiotics are given at induction.
  • Lateral collateral ligament injury. Over-aggressive release can extend into the underlying lateral collateral ligament complex and cause posterolateral rotatory instability of the elbow. Careful technique avoids this.
  • Nerve irritation. Branches of the lateral antebrachial cutaneous nerve cross the operative field. Temporary numbness over a small area on the outer forearm is uncommon and usually settles.
  • 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

When does tennis elbow need surgery?
Most cases settle without surgery. Surgery is considered only after at least six months of structured non-operative treatment, including activity modification, eccentric-loading physiotherapy, a counter-force brace, and selective injection therapy. The threshold for surgery is significant pain that limits everyday activities such as gripping, lifting, or work tasks. Even then, the decision is individual and depends on the patient and the response to earlier treatment.
What does the surgery actually do?
The diseased portion of the extensor carpi radialis brevis (ECRB) tendon origin is identified and excised. Despite the name "epicondylitis", the underlying problem is tendon degeneration rather than inflammation. The aim is to remove the chronic degenerative tissue, prepare the bony footprint, and allow healthy tendon to heal back to the lateral epicondyle. Some surgeons add a small repair after the release to anchor the tendon back to the bone.
Is the surgery open or arthroscopic?
Both are valid. Open release uses a small incision over the lateral epicondyle and gives direct visualisation of the ECRB origin. Arthroscopic release is done through a small camera inside the elbow joint and allows assessment of intra-articular pathology at the same time. The choice depends on the clinical findings and surgeon preference. Outcomes are broadly similar between the two techniques.
What does recovery look like?
A sling or splint for one to two weeks for comfort. Range of motion exercises start within the first week. Strengthening progresses from around six weeks. Most patients return to office work within a week or two, to driving by two to four weeks, and to full unrestricted activity by three to four months. Some residual ache with heavy gripping can persist for several months and gradually settles.
How successful is the surgery?
The majority of patients have substantial pain relief and a return to function. Outcomes are best when the diagnosis is clear, non-operative treatment has been thorough, and the patient understands that recovery is gradual rather than immediate. A small number of patients have residual symptoms that improve over a longer period or do not fully resolve, particularly with heavy repetitive work.
