Kinematics Team Common Extensor Tendon Degeneration (Tennis Elbow)
September 1stThat ache on the outside of your elbow might seem small until picking up the kettle, gripping the steering wheel, or shaking someone’s hand suddenly makes you think twice.
Despite the name, you definitely don’t need to play tennis to develop tennis elbow. It’s something we regularly see in desk workers, tradies, gym-goers, and anyone whose arm is repeatedly asked to grip, lift, or work under load. Here’s what’s actually going on.
Common Extensor Tendon Degeneration. On the outside of your elbow is a bony point called the lateral epicondyle where several forearm muscles attach via a shared tendon. These muscles help lift your wrist and fingers when doing everyday tasks like, typing, carrying shopping bags and driving. Unlike an acute strain, tennis elbow symptoms usually worsens gradually overtime without one obvious moment when it started.
The word “degeneration” can sound alarming. It doesn’t mean your tendon has suddenly torn or is permanently damaged, the tendon has gradually become less able to tolerate the load being placed through it. Think of a rope that’s been repeatedly loaded without enough recovery. Its fibres become less organised and resilient, but the rope is still intact.
Where will I feel pain with an extensor tendon degeneration?
Right over that bony point on the outside of your elbow, you’ll often find one particularly tender spot when you press around the area. The pain can also travel a short distance down the top of your forearm, especially after a demanding day of gripping, lifting, or typing. There are times where rather than feeling the discomfort directly at the elbow, you may notice that the muscles in your forearm simply feel tired, tight, or tender.
What movements will I struggle to perform if I have degeneration in my extensor tendon?
Gripping is often one of the main actions you’ll find difficult. This can include everyday tasks like opening a stubborn jar, carrying shopping bags, or even lifting a saucepan. Unfortunately, prolonged activities such as using a mouse for hours or driving on a long trip can also aggravate the area.
One particularly provocative position is lifting with your elbow straight and your palm facing down. This places greater demand on the irritated tendon and is often one of the first movements people start to avoid.
Will I feel pain in any other regions of my body?
When something hurts you naturally want to protect the area and start moving around it. You may hold your arm differently, use your shoulder more, or stiffen through your wrist without even noticing.
Over time, this can show up as tightness around the shoulder, neck, wrist, or forearm on the same side. Knowing that your elbow doesn’t work in isolation the rest of your upper body is compensating and this would need to be addressed to shape a more complete rehabilitation plan.
How does a common extensor tendon degeneration happen?
It generally begins when the demands placed on the tendon exceed its current capacity to recover. Sometimes the cause is obvious, such as painting all weekend, moving house, or suddenly increasing your gym training. Other times, it’s a gradual build-up from repetitive gripping, computer work, using tools, or regular lifting, with the tendon becoming increasingly irritated over time.
Reduced forearm and grip strength, age-related changes in the tendon, and not allowing enough time for recovery between demanding activities can all influence how much load your tendon can comfortably tolerate.
What things should I try initially once I’ve common extensor tendon degeneration?
Start by modifying the activities that are aggravating the area rather than stopping everything altogether. Complete rest is rarely the goal, as tendons need an appropriate amount of load to maintain and gradually rebuild their capacity. The key is finding the level of activity your tendon can comfortably tolerate.
If symptoms flare up, applying ice for 10–15 minutes may help settle things down. A wrist brace or elbow strap can also sometimes reduce the demand on the tendon during work or heavier activities. Gentle wrist and forearm mobility, performed within a comfortable range, can help keep the area moving without unnecessarily aggravating it.
What things should I try to avoid in the initial stages of an extensor tendon degeneration?
Heavy gripping and repeated lifting with a straight arm and palm facing down are common irritants early on. Pay attention to the type of pain, too. A mild, manageable ache can be very different from a sharp spike that keeps escalating. Repeatedly forcing painful handshakes, heavy boxes, or gripping tasks can keep re-irritating the tendon. Deep massage directly over an acutely tender point may do the same. The aim is to temporarily dial down the most provocative loads while rebuilding your capacity.
What type of exercises or movements do I need to learn to rehab the extensor tendon?
Rehabilitation often begins with isometric exercises, creating tension through the wrist muscles without actually moving the joint.
From there, strengthening becomes progressively more challenging. Slow, controlled wrist exercises are introduced through a larger range, with resistance increasing as your tolerance improves.
Grip strength and endurance matter too. Your tendon doesn’t only need to handle one repetition, it may need to survive eight hours at a keyboard, repeated tool use, or an entire training session.
Faster, more task-specific movements generally come later, once slower loading is well tolerated.
What other considerations contribute to the degeneration of the extensor tendon?
Your elbow is only one part of the picture. Desk height, mouse position, tool-handle size, and gripping technique can subtly change how much work your forearm has to do. Shoulder and upper-limb strength matter as well. If capacity is lacking elsewhere, your forearm may end up carrying more of the load.
Recovery counts too. Poor sleep and prolonged stress can influence tissue recovery, which is why we look beyond one painful spot. Work, training, hobbies, and recovery all contribute to your overall load.
What treatments can help relieve some pain or fast track my extensor tendon rehabilitation?
A thorough assessment helps work out what is actually driving your symptoms. That can include testing grip strength and wrist movement, reproducing the movements that trigger your pain, and checking whether symptoms could be influenced by other muscles, joints or the nerves beginning in the neck.
From there, treatment may combine activity modification, progressive strengthening, hands-on treatment for relevant stiffness and the use of taping or bracing where appropriate.
If work or sport involves significant gripping, your plan should also build towards those exact demands. Getting comfortable is one step. Building enough capacity to stay comfortable when normal life ramps back up is the bigger goal.
What are the expected timeframes of rehabilitating extensor tendon?
There’s no universal stopwatch for tendon rehabilitation. Milder, more recent cases may improve within four to six weeks when loading is appropriately managed and progressed. Longer-standing symptoms, particularly those present for six months or more, may require three to six months of structured rehabilitation.
Tendons adapt more slowly than muscles. Trying to rush that process can simply create another flare-up.
If your elbow pain has been hanging around for more than a couple of weeks, or it’s interfering with work, training or everyday tasks, getting it properly assessed can remove a lot of the guesswork.
At Kinematics, the goal isn’t simply to calm the painful spot. Book an appointment to understand what your elbow needs, rebuild its capacity, and give you a clear pathway back to the things you actually want to do.
