Tennis elbow (medical term: lateral epicondylitis) is an overuse injury affecting the tendons in the outside of the elbow joint. It usually presents with weak grip strength and a painful soreness or burning sensation in the outside of the elbow. Tennis elbow can be a sports injury, but its causes vary — and some may surprise you.
Tennis elbow is a type of tendinitis (sometimes spelled "tendonitis") of the elbow, affecting the muscles and tendons that control the use of the forearm — specifically, the extension of the wrist and fingers.
Any repetitive motion that extends the wrist and fingers can cause tiny tears and inflammation in the muscles and tendons of the forearm. This, in turn, causes elbow pain and weakness when gripping objects.
Lateral epicondylitis is caused by damage to a forearm muscle called the extensor carpi radialis brevis (ECRB). This muscle is responsible for stabilizing your wrist when your arm is extended (in a straight position).
Sometimes, the ECRB can become weakened or strained from frequent bending and straightening of the elbow. This overuse may result in tiny tears in the tendons that attach the ECRB muscle to bone. These tears are the cause of the inflammation and pain we call tennis elbow.
As implied by its name, tennis elbow is frequently seen in tennis players — particularly in athletes who are using a poor stroke technique or a loosely-strung racket.
However, anyone can develop the condition. Repetitive motion is the chief cause; any activity that relies on the heavy use of your forearm muscles can lead to injury.
Tennis elbow is also more common if you're between the ages of 30 and 50.
Activities that can cause tennis elbow include:
People who work in certain occupations that involve frequent lifting, gripping, or repetitive arm movements are also prone to developing tennis elbow.
Occupations where tennis elbow is common include:
Tennis elbow often begins with mild symptoms and develops gradually until the pain disrupts normal activities. Symptoms mainly affect the outside of the elbow. Signs of tennis elbow include:
If you think you may have tennis elbow, a visit to a doctor is advisable. During your exam, your doctor will ask you questions about your symptoms; for example:
Your doctor may then ask you to perform a tennis elbow test: straightening your wrist and fingers against resistance while your arm is fully straight. If this test causes you pain, you may have muscle damage in the forearm.
Other tests that may be necessary to diagnose your condition can include:
The majority of people are able to treat their tennis elbow non-surgically. If you have tried the following approaches and they haven't worked for you, surgery may offer relief (skip ahead to the end of this article for more information).
If you're suffering from severe or chronic tennis elbow and none of the above treatments have worked to ease your symptoms within 6 to 12 months, you may be advised by your doctor to consider tennis elbow surgery. Tennis elbow surgery is a highly successful procedure that resolves symptoms in 80% to 90% of patients.
Most of the time, surgery requires removing diseased parts of your muscle and reattaching the healthy muscle back to the bone. Orthopedists can perform either open surgery on the elbow or arthroscopy, which is less invasive.
Your doctor will make an incision over the elbow. Diseased muscle is then removed; healthy muscle is reattached to bone; and the incision is sutured closed.
Open surgery is the most commonly performed tennis elbow repair surgery, and can usually be done on an outpatient basis at a surgical center. You will most likely be in and out in the same day.
Arthroscopic elbow surgery is minimally invasive and preferred by some patients. Your doctor will make small incisions and insert a camera scope and miniature instruments into your elbow. As with open surgery, the goal if arthroscopy is to remove diseased muscle and reattach healthy muscle to the bone.
Arthroscopic surgery is a same-day outpatient procedure.
After surgery, your orthopedist may immobilize your elbow with a splint that you'll wear for about one week. After that week, you'll return to the doctor's office to have your sutures and the splint removed.
A week after surgery, post-surgical rehab begins with exercises to gently stretch your elbow and restore your flexibility and range of motion.
Two months after surgery, you will be prescribed strengthening exercises.
If you're an athlete, you can expect to return to sports within four to six months after surgery.
If your tennis elbow is causing you daily pain and stiffness and is not responding to non-surgical treatments, it may be time for you to consider surgery.
