Overview
Tennis elbow (lateral epicondylitis) is a breakdown of the tendon that anchors the wrist extensor muscles, chiefly the extensor carpi radialis brevis, to the bony point on the outside of the elbow. Golfer's elbow (medial epicondylitis) is the same process on the inside, at the origin of the wrist flexors and pronator teres. Despite the name, neither is mainly an inflammation: the tendon shows disorganized collagen and tiny tears, a failed-healing state called tendinosis.
Treatment is decided by duration and by response to a proper loading program. The large majority of patients recover with 3 to 6 months of structured rehabilitation. An ultrasound-guided PRP injection is added for tendons that fail to improve. Surgery is reserved for the small group with symptoms beyond 6 to 12 months, a degenerate or torn tendon on imaging, and a completed rehabilitation program that has not worked.
Common Symptoms
- Tennis elbow: pain at the outer elbow spreading down the top of the forearm with gripping, lifting palm-down (a kettle, a grocery bag), shaking hands or turning a stiff key
- Golfer's elbow: pain at the inner elbow with gripping, wrist bending, turning the forearm palm-down, the golf swing, throwing or pull-ups
- A weak, painful grip; dropping things
- Tenderness directly over the bony point of the outer or inner elbow
Inner-elbow pain in a thrower that appears in the late cocking phase and comes with a loss of velocity is more likely a UCL injury than golfer's elbow. Numbness in the small finger as the main symptom is cubital tunnel syndrome. Outer-elbow pain in an elbow that no longer straightens fully suggests elbow arthritis.
Causes & Risk Factors
The tendon breaks down when it is loaded more often, or harder, than it can repair. On the outer side that is repetitive wrist extension and gripping: a backhand hit with the wrist leading, hours with a mouse, painting, carpentry. On the inner side it is wrist flexion and pronation: golf, throwing, climbing, hammering. A sudden increase in volume is the usual trigger. It peaks between 35 and 55 and is uncommon in teenagers, whose elbow pain more often means a ligament or cartilage problem.
How It Is Diagnosed
For tennis elbow Dr. O'Donnell finds the point of maximal tenderness just distal to the lateral epicondyle and reproduces the pain with Cozen's test (resisted wrist extension with the elbow straight), Maudsley's test (resisted middle-finger extension) and Mill's test (passive wrist flexion with the elbow straight). For golfer's elbow the tenderness sits just in front of the medial epicondyle and the pain is reproduced with resisted wrist flexion and pronation. The UCL and the ulnar nerve are checked at the same visit.
X-rays are taken when the elbow is stiff, injured or not responding; they exclude arthritis and loose bodies. Office ultrasound shows the thickened tendon and any partial tear, and guides injections. MRI is ordered when surgery is being considered. Visiting patients can upload existing imaging through mymedicalimages.com.
Treatment Options
Non-operative care
Rehabilitation follows Dr. O'Donnell's written programs for both conditions. Weeks 0 to 2 are pain control: relative rest from repetitive gripping, palm-up lifting, a counterforce brace, ice after activity, and a review of tools, grip size and technique. Weeks 2 to 6 introduce stretching, isometric holds, and the start of eccentric strengthening, most simply the Tyler twist with a rubber resistance bar, the single most effective component. Weeks 6 to 12 progress to full eccentric and concentric strengthening and grip work while the aggravating tasks are reintroduced. From month 3 the program is sport- or job-specific. Some discomfort with loading is expected; sharp pain is not.
Corticosteroid injection is used sparingly. It relieves pain for a few weeks, but patients who receive it do worse at 6 and 12 months than those who do not, and repeat injections weaken the tendon. For a tendon that has not responded by 3 to 6 months, Dr. O'Donnell offers an ultrasound-guided platelet-rich plasma injection into the degenerate tendon to stimulate healing; the loading program continues afterward.
Tennis or golfer's elbow release
For the small group who meet those criteria, Epicondylitis release removes the diseased portion of the tendon origin and repairs the healthy tissue; on the outer side it can be done arthroscopically, and on the inner side through a small open incision with the ulnar nerve protected. It is a short outpatient operation.
Recovery & What to Expect
Recovery is measured in months with or without surgery, and the two follow similar timelines from Dr. O'Donnell's protocols.
| Phase | Non-operative program | After release surgery |
|---|---|---|
| Weeks 0–2 | Pain control: activity modification, counterforce brace, palm-up lifting, ice, ergonomic review | Protection: splint or soft dressing, gentle wrist and finger motion, no resisted wrist activity |
| Weeks 2–6 | Stretching, isometric holds, start of eccentric loading (Tyler twist), manual therapy as needed | Full active motion, gentle stretching, scar mobilization; no resisted wrist extension or forceful gripping |
| Weeks 6–12 | Progressive eccentric and concentric strengthening, grip work, gradual return to aggravating tasks | Isometric, then eccentric, then concentric strengthening; grip and forearm conditioning |
| Month 3 on | Sport- or job-specific loading and maintenance; discharge on painless function and symmetric grip | Sport- or job-specific progression through months 3–6; discharge on symmetric strength |
Desk work continues throughout non-operative care and resumes within a week of surgery; driving is reasonable one to two weeks after release; racquet sports, golf and manual work return gradually from month 3. The programs are available as PDFs: tennis elbow, non-operative, golfer's elbow, non-operative, and after release surgery.
Frequently Asked Questions
Can tennis elbow heal on its own?
Usually, but slowly, and rarely while you keep doing what caused it. Left alone it tends to run 12 to 18 months. A structured program of load management and eccentric strengthening shortens that to about 3 to 6 months for most patients and lowers the chance it comes back.
Should I get a cortisone shot for tennis elbow?
Generally no. It gives good relief for a few weeks, but trials show patients who had the injection are worse at 6 and 12 months than those who did rehabilitation alone, and repeated injections weaken the tendon. Dr. O'Donnell reserves it for the rare patient who cannot start therapy because of pain.
Does a tennis elbow brace work?
A counterforce strap spreads the pull of the muscles away from the sore tendon origin and reduces pain with gripping. It is a useful part of the first weeks, not a treatment by itself; the tendon recovers because of the loading exercises.
Does PRP work for tennis elbow or golfer's elbow?
After 3 to 6 months of rehabilitation without improvement, an ultrasound-guided PRP injection into the degenerate tendon improves pain and function in a good share of patients, with better durability than cortisone. The eccentric program continues afterward and full effect takes 2 to 3 months.
When does tennis elbow need surgery?
Rarely. Surgery is discussed after 6 to 12 months of symptoms, a completed rehabilitation program, and imaging showing a degenerate or torn tendon. The release removes the diseased tissue and reattaches the healthy tendon, and recovery follows a 3 to 6 month program with no resisted wrist extension for the first 6 weeks.
