Tennis Elbow

Introduction

Tennis elbow is a common cause of pain on the outer side of the elbow. Despite the name, most people who develop it have never picked up a tennis racquet. It is a condition of the tendons that attach the forearm muscles to the bony bump on the outside of the elbow, and it usually develops gradually from repeated gripping, lifting, or twisting movements.

If you have been told you have tennis elbow, or if you are dealing with persistent outer-elbow pain, this guide walks through what is happening in the tendon, how the condition is diagnosed, and the full range of management options — from simple measures at home, through physiotherapy and injections, to surgery in the small number of cases where it becomes necessary. It also covers recovery timelines and how to reduce the chance of the problem returning.

Tennis elbow can be frustrating because it often takes longer to settle than people expect. Understanding why that is, and what each treatment is actually trying to do, can make the months of recovery feel less uncertain.

What Is Tennis Elbow?

Tennis elbow is the everyday name for a condition doctors call lateral epicondylitis or, more accurately, lateral elbow tendinopathy. The lateral epicondyle is the small bony bump you can feel on the outer side of your elbow. Several forearm muscles — the ones that straighten your wrist and fingers — share a common tendon that attaches to this bump. The tendon most often involved belongs to a muscle called the extensor carpi radialis brevis.

A tendon is a strong band of tissue that connects muscle to bone. In tennis elbow, repeated stress on this tendon causes small tears and changes in the tendon’s structure. The tissue does not heal as cleanly as it should, and the result is a tendon that is weakened, sensitive, and painful when loaded.

An important point: although the older name “epicondylitis” suggests inflammation (the suffix “-itis” means inflammation), research over the past two decades has shown that tennis elbow is mostly a problem of tendon degeneration rather than active inflammation. This matters because it explains why anti-inflammatory medicines and steroid injections can settle pain but do not heal the tendon, and why loading the tendon gradually through exercise is at the centre of long-term recovery.

Tennis elbow most commonly affects people between 30 and 50 years of age. Men and women are affected roughly equally. The dominant arm is involved more often, but the non-dominant side can also develop the condition.

Causes and Risk Factors

Tennis elbow develops when the tendon is loaded repeatedly in ways it cannot fully recover from between uses. The trigger is rarely a single injury — it is usually the cumulative effect of many small stresses.

Activities Commonly Linked to Tennis Elbow

• Manual work involving repeated wrist movements, gripping, or use of tools — carpentry, plumbing, painting, masonry, mechanics, butchery
• Office work with prolonged keyboard and mouse use, particularly with poor wrist posture
• Cooking and household tasks involving chopping, wringing, lifting heavy pans
• Sports that load the forearm: tennis, badminton, squash, table tennis, climbing, weight training
• Music — certain instruments that require sustained wrist or grip activity

In racquet sports, tennis elbow is often linked to technique, racquet weight, string tension, and grip size. In manual workers, sudden increases in workload or new tools are common triggers.

Risk Factors

• Age 30 to 50
• Occupations that require repetitive forearm activity
• Sudden increase in activity level or training intensity
• Smoking, which slows tendon healing
• Other tendon problems elsewhere in the body
• Diabetes, which is linked to slower tendon recovery
• Poor forearm conditioning relative to the demand placed on it

Signs and Symptoms

The hallmark of tennis elbow is pain or tenderness on the outer side of the elbow. The pain often begins mildly and builds over weeks. It may be felt as:

• A sore or burning sensation on the outside of the elbow, sometimes radiating down the forearm
• Pain when gripping — lifting a kettle, turning a doorknob, shaking hands, holding a cup
• Weakness of grip, with objects slipping from the hand
• Pain when straightening the wrist or fingers against resistance
• Stiffness in the elbow, particularly first thing in the morning
• Pain that worsens with the activity that triggered it

Tennis elbow usually does not cause swelling, redness, or restricted elbow bending and straightening. If those features are present, the doctor will consider other diagnoses such as arthritis or infection.

Symptoms can last from several weeks to many months. In many people they settle gradually with time and self-management; in others they persist and need active treatment.

Diagnosis

Tennis elbow is usually diagnosed clinically — that is, through a careful history and physical examination, without needing complex tests. Imaging is used selectively to confirm the diagnosis, rule out other problems, or guide treatment when the picture is unclear.

History and Physical Examination

The doctor will ask about your work, sports, and daily activities, when the pain started, how it has changed over time, and what makes it better or worse. The physical examination typically includes:

• Pressing on the bony bump on the outer elbow to find the tender spot
• Asking you to straighten your wrist or middle finger against resistance, which usually reproduces the pain
• Checking grip strength, which is often reduced on the affected side
• Checking the elbow’s range of motion and the neck and shoulder to rule out referred pain

Imaging

Imaging is not always needed. When it is used, the common options are:

• X-ray — to look for arthritis or calcium deposits if the pain pattern is unusual or has lasted a long time
• Ultrasound — to look directly at the tendon for thickening, small tears, or changes in tissue quality; also used to guide injections
• MRI — reserved for cases where the diagnosis is unclear, where surgery is being considered, or where there is concern about other elbow structures

If the doctor suspects a problem coming from the neck (a pinched nerve) or another condition mimicking tennis elbow — such as radial tunnel syndrome — further tests, including nerve studies, may be arranged.

Non-Surgical Treatment

For most people, tennis elbow improves without surgery. Studies and clinical experience consistently show that the large majority of cases resolve within 6 to 12 months with conservative care, though recovery is often slower than patients hope. The goals of non-surgical treatment are to settle pain, allow the tendon to recover, and gradually rebuild its capacity to handle load.

Activity Modification and Rest

Cutting out or changing the activity that triggered the pain is the first step. This does not usually mean complete rest of the arm — that can make the tendon weaker. It means reducing the specific aggravating movements and finding ways to perform daily tasks with less strain on the tendon.

For office workers, this may involve adjusting desk and keyboard position. For manual workers, it may mean rotating tasks, using different tools, or temporarily switching duties. For athletes, technique changes, lighter equipment, or a break from the sport may be needed.

Ice and Heat

Ice can ease pain after activity. Heat is sometimes more comfortable before activity to loosen the area. Neither changes the underlying tendon condition, but both can help day-to-day comfort.

Pain Relief Medication

Simple painkillers such as paracetamol, or anti-inflammatory medicines such as ibuprofen, can reduce pain and make exercise and daily life more manageable. Topical anti-inflammatory gels are also commonly used and avoid some of the side effects of tablets. Medication is for symptom relief; it is not a treatment for the tendon itself.

Bracing

Two types of brace are used:

• Counterforce brace — a band worn around the upper forearm, just below the elbow. It changes the way force is transmitted through the tendon and can reduce pain during activity.
• Wrist splint — worn at night or during heavy tasks to keep the wrist still and reduce repeated pulling on the tendon.

Bracing is most useful as a short- to medium-term aid alongside other treatments rather than as a long-term solution.

Physiotherapy

Physiotherapy is the cornerstone of recovery in tennis elbow. Current orthopaedic and sports medicine guidance places progressive loading exercises at the centre of treatment, particularly a type called eccentric exercise, where the muscle lengthens under load. These exercises encourage the tendon to remodel and rebuild its capacity.

A typical physiotherapy programme includes:

• Stretching of the forearm muscles
• Progressive strengthening, starting gentle and building up over weeks
• Eccentric loading exercises, often using a light weight or resistance band
• Manual therapy techniques applied by the therapist
• Advice on posture, ergonomics, and technique

Progress is slow, often measured over months rather than weeks. Sticking with the programme even when results feel modest is what makes the difference.

Shockwave Therapy

Extracorporeal shockwave therapy delivers focused pressure waves to the tendon. It is offered in some clinics for tennis elbow that has not responded to first-line care. Evidence is mixed but several studies show modest benefit in selected patients.

Injection Treatments

When pain remains a major problem despite activity changes, bracing, and physiotherapy, injection treatments are sometimes considered.

Corticosteroid Injection

A steroid injection into the tender area can give short-term pain relief, often within days. However, research over the past 15 years has shown that while steroid injections work well in the first few weeks, people who receive them tend to have worse outcomes at 6 to 12 months compared with those who do not. Because of this, current orthopaedic guidance generally favours using steroid injections sparingly, often reserving them for a specific situation — for example, when pain is preventing someone from doing physiotherapy at all.

Platelet-Rich Plasma (PRP) Injection

PRP involves taking a small sample of your own blood, concentrating the platelets, and injecting them into the tendon. The aim is to deliver growth factors that may support tendon healing. Evidence is still developing, but several studies suggest PRP can provide longer-lasting benefit than steroid for some patients with persistent tennis elbow. It is one of the options orthopaedic surgeons may consider when first-line care has not worked.

Other Injection Options

Other injections studied for tennis elbow include autologous blood injections, hyaluronic acid, and botulinum toxin. Their roles are less well established and they are offered selectively.

Whether any injection is appropriate, and which type, is a clinical decision based on how long symptoms have lasted, what has already been tried, and the look of the tendon on imaging.

When Surgery Is Considered

Surgery is reserved for the small number of people whose symptoms have not settled despite a thorough course of non-surgical treatment. The usual threshold is symptoms that have lasted at least 6 to 12 months and have not responded to a structured programme of activity modification, physiotherapy, bracing, and, where appropriate, injection therapy.

Factors that doctors weigh when considering surgery include:

• Length and severity of symptoms
• Impact on work, sport, and daily life
• Findings on examination and imaging, including the presence of partial tendon tears
• What treatments have already been tried, and for how long
• General health and ability to engage with rehabilitation afterwards

The aim of surgery is to remove the damaged, degenerated part of the tendon and to encourage a healthy healing response. Surgery does not always relieve pain completely, and recovery still takes months, so the decision is made carefully.

Surgical Approaches

Several surgical techniques are used for tennis elbow. The choice depends on the surgeon’s training, the appearance of the tendon, and whether other problems inside the elbow joint are suspected.

Open Surgery

Open surgery gives a clear view of the tendon and a long track record of results. It involves a slightly larger incision than the other approaches and a visible scar.

Arthroscopic Surgery

Arthroscopic surgery uses a small camera (an arthroscope) and fine instruments inserted through tiny incisions. The surgeon can look inside the elbow joint, address the diseased tendon from inside, and check for other problems such as loose bodies or joint surface damage. Compared with open surgery, the arthroscopic approach typically involves smaller scars and may allow slightly earlier return of motion, though long-term outcomes appear broadly similar.

Percutaneous Tenotomy

Percutaneous tenotomy is a less invasive technique performed through a very small incision, often with ultrasound guidance. The diseased tendon tissue is divided or removed without a larger surgical exposure. It is generally suited to certain patterns of disease and is offered in selected centres.

Across all three approaches, the underlying principle is the same: remove the damaged tissue and create conditions for healthier tendon to take its place. Which approach is most appropriate is a clinical decision discussed with the surgeon, based on the individual case.

Preparing for Surgery

If surgery is planned, the preparation usually includes:

• A detailed discussion of the procedure, alternatives, risks, and expected recovery
• Blood tests and, depending on age and health, an electrocardiogram (ECG)
• A review of medications — some, such as blood thinners and certain anti-inflammatories, may need to be paused
• Stopping smoking, where applicable, to support tendon healing
• Arranging help at home for the first week or two after surgery
• Practical planning for time off work, with timing depending on the type of work

First Few Days

The arm is supported in a sling or splint. Pain is managed with prescribed medication. The wound is kept clean and dry. Gentle finger and shoulder movements are usually encouraged to prevent stiffness elsewhere.

Two to Six Weeks

The splint or sling is gradually discarded. Stitches are removed if not dissolvable. Physiotherapy begins, focusing on regaining elbow and wrist motion and starting very light strengthening.

Six Weeks to Three Months

Strengthening progresses. Many people return to office-based work during this period. Heavy lifting and high-load gripping are still avoided.

Three to Six Months

Most people see substantial improvement during this stage. Return to manual work, sport, and heavier activity is gradual and guided by symptoms and strength.

Six to Twelve Months

Final recovery, including return to full sport or demanding manual work, may take up to a year. Some mild residual symptoms can persist longer in a minority of patients.

Sticking with physiotherapy is the single biggest factor in the quality of recovery after surgery.

Risks and Complications

Tennis elbow surgery is generally safe but, like any operation, carries risks. Your surgeon will discuss these in detail. Possible complications include:

• Persistent pain — pain may not improve as much as hoped, or in a small minority, may not improve at all
• Infection — usually superficial and treated with antibiotics; deep infection is rare
• Nerve irritation — small nerves near the surgical area can be irritated or, rarely, injured, causing numbness or tingling
• Stiffness of the elbow, particularly if early movement is limited
• Scar tenderness at the incision site
• Weakness of grip, usually temporary
• Recurrence of symptoms over time
• Risks of anaesthesia, which the anaesthetist will discuss separately

Reported outcomes from tennis elbow surgery are generally good, with most patients experiencing meaningful improvement in pain and function, but it is honest to say that surgery is not a guarantee.

Long-Term Management and Preventing Recurrence

Whether you have recovered with non-surgical treatment or with surgery, tennis elbow can return if the underlying loading patterns that caused it are not addressed. Long-term management focuses on protecting the tendon while keeping it strong.

Maintain Forearm Strength

Continuing the strengthening and stretching exercises learned in physiotherapy — even briefly, a few times a week — helps the tendon stay resilient. Many people stop their exercises once pain goes away and find symptoms return months later.

Address Ergonomics

Reviewing how you work is often more important than any single treatment. Useful adjustments include:

• A keyboard and mouse position that keeps the wrist neutral
• Tools with appropriate grip size and weight
• Frequent micro-breaks during repetitive tasks
• Sharing tasks across both hands where possible

Review Sports Technique and Equipment

For racquet and bat sports, a coach’s review of technique, grip size, racquet weight, and string tension can make a significant difference. Warm-up and gradual build-up of training load are essential.

Manage Overall Health

Tendon health is influenced by general health. Stopping smoking, managing blood sugar in diabetes, and maintaining a reasonable level of overall fitness all support tendon recovery and resilience.

Listen to Early Symptoms

If outer-elbow pain begins to return, addressing it early — with rest, technique adjustments, and a return to the physiotherapy exercises — is usually more effective than waiting until it is severe.

Living with Tennis Elbow During Recovery

Tennis elbow tests patience. The pain is often more limiting than people expect, and progress can feel slow. A few practical points may help:

• Recovery is rarely linear. Good days and bad days are normal. The trend over weeks is what matters.
• Some discomfort during exercise is acceptable. Physiotherapy guidance usually allows mild pain during loading exercises if it settles afterwards. Sharp or worsening pain is a signal to adjust.
• Use the unaffected hand for heavy tasks where possible during the painful phase, but avoid completely abandoning the affected arm — gentle, controlled use is part of healing.
• Sleep position matters. Avoid sleeping on the affected arm or with the wrist flexed under the body.
• Expect months, not weeks. Understanding the typical timeline can reduce frustration.

Frequently Asked Questions

Do I have to play tennis to get tennis elbow?

No. Most people diagnosed with tennis elbow have never played tennis. The condition is caused by any repeated loading of the forearm tendons — common in office work, manual trades, cooking, and many sports.

How long does tennis elbow usually last?

Most cases settle within 6 to 12 months with appropriate management, though some people recover faster and a minority have symptoms that persist longer. Recovery is often slower than patients expect.

Will it heal on its own without treatment?

Many cases do gradually improve on their own, particularly if the triggering activity is modified. Active treatment — especially physiotherapy — usually speeds and improves the recovery.

Are steroid injections a good idea?

Steroid injections give fast short-term pain relief but research has shown that people who receive them often have worse outcomes at 6 to 12 months compared with those who do not. Current orthopaedic guidance generally favours using them sparingly. Whether an injection is appropriate in your case is a clinical decision based on the specifics of your situation.

How is tennis elbow different from golfer’s elbow?

Both are tendinopathies around the elbow caused by overuse. Tennis elbow affects the tendon on the outer side of the elbow, where the muscles that straighten the wrist attach. Golfer’s elbow affects the tendon on the inner side, where the muscles that bend the wrist attach. The principles of treatment are similar.

Can tennis elbow come back after it has settled?

Yes. Recurrence is possible, particularly if the activities or loading patterns that caused it have not changed. Continuing strengthening exercises and adjusting ergonomics or technique helps reduce this risk.

How soon after surgery can I return to work?

It depends on the type of work. Office-based work is often possible within 2 to 4 weeks. Heavy manual work usually requires longer — commonly 3 months or more — with a graded return.

Is physiotherapy really necessary?

For most people, yes. Progressive loading exercise is at the core of tendon recovery, both for non-surgical treatment and after surgery. Skipping or rushing this stage is a common reason for poor outcomes and recurrence.

Can imaging tell how severe my tennis elbow is?

Ultrasound and MRI can show changes in the tendon, but the appearance does not always match how severe the pain or limitation feels. Some people with marked changes have mild symptoms and the reverse is also true. Imaging is used to confirm the diagnosis and guide treatment, not as the sole measure of severity.

Conclusion

Tennis elbow is a tendon problem of the outer elbow that almost always begins with overuse. The most important things to understand are that it is rarely a simple inflammation, that recovery is usually measured in months, and that the great majority of people improve without surgery when they engage with a structured programme of activity modification, physiotherapy, and patient persistence.

When pain persists despite a thorough course of non-surgical care, injections or, less often, surgery are options that orthopaedic surgeons may consider. Each carries its own balance of benefits and risks, and the right path is best decided in conversation with a specialist who knows the details of your case. Whatever the route, returning to the activities and work you value is a realistic goal — and protecting the tendon afterwards, through ongoing strength work and sensible loading, is what keeps the problem from coming back.
