Triceps tendinopathy is an overuse condition affecting the triceps tendon, which connects the triceps muscle at the back of the upper arm to the olecranon (tip of the elbow). The triceps muscle is responsible for straightening the elbow and plays a key role in pushing, throwing, weight-bearing through the arms, and many sporting and gym-based activities.
This condition develops when the triceps tendon is exposed to repetitive or excessive loading that exceeds its capacity to recover. Over time, this leads to tendon pain, reduced strength, and impaired function. Despite often being labelled as “tendonitis”, triceps tendinopathy is usually not an inflammatory condition but rather a disorder of tendon load tolerance and structure.
Triceps tendinopathy is less common than other elbow tendon conditions such as lateral or medial epicondylalgia, but it is frequently seen in athletes, manual workers, and individuals who perform repetitive pushing or heavy upper limb loading. Physiotherapy for triceps tendinopathy is the cornerstone of management and focuses on restoring tendon capacity, reducing pain, and safely returning people to their desired activities.
Key Facts
- Triceps tendinopathy is an uncommon but recognised cause of posterior elbow pain, particularly in strength athletes and throwing sports. 🔗
- Distal triceps tendinopathy is the rarest tendinopathy seen around the elbow 🔗
- It typically causes pain at the back of the elbow, especially when pushing, pressing, or straightening the elbow against resistance. 🔗
Risk Factors
- Repetitive or heavy upper limb pushing activities.
- Sudden increases in training volume or intensity.
- Strength sports such as weightlifting, CrossFit, and bodybuilding.
- Throwing or overhead sports.
- Poor load management or inadequate recovery.
- Reduced shoulder or trunk strength and control.
Symptoms
- Pain at the back of the elbow, particularly near the tip of the olecranon.
- Pain with pushing movements such as push-ups, bench press, or pushing doors.
- Pain during or after throwing, punching, or overhead activities.
- Local tenderness over the triceps tendon insertion.
- Morning stiffness or pain at the start of activity that may ease as you warm up.
- Reduced strength or confidence when straightening the elbow under load.
Aggravating Factors
- Heavy pushing exercises such as bench press, dips, or overhead press.
- Repetitive throwing or striking activities.
- Supporting body weight through the arms (e.g. push-ups, handstands).
- Sudden increases in training load or intensity.
- Prolonged elbow extension under load.
Causes
Triceps tendinopathy develops when the triceps tendon is repeatedly loaded beyond its current capacity to adapt and recover. This often occurs with repetitive pushing, throwing, or heavy resistance training, particularly when load is increased too quickly.
Rather than being driven by inflammation, the tendon undergoes structural and biochemical changes that reduce its ability to tolerate tensile and compressive forces. As a result, pain is produced when the tendon is stressed, especially near its insertion at the elbow.
Biomechanical factors such as poor lifting technique, reduced shoulder or thoracic mobility, and weakness or poor control through the kinetic chain can increase stress on the triceps tendon. Fatigue also plays a significant role, as tendon loading capacity decreases when muscles tire.
From a physiotherapy perspective, triceps tendinopathy is managed by addressing both local tendon capacity and the broader movement patterns that contribute to excessive elbow loading.
How Is It Diagnosed?
Triceps tendinopathy is primarily diagnosed clinically. A physiotherapist will take a detailed history focusing on training load, aggravating activities, and symptom behaviour over time.
Physical examination typically reveals localised tenderness over the triceps tendon and pain reproduced with resisted elbow extension, particularly near full extension or under heavier loads. Range of motion is usually preserved, although pain may limit end-range effort.
It is important to rule out other causes of posterior elbow pain such as olecranon bursitis, stress fracture, or referred pain from the cervical spine. Imaging is not routinely required but may be used when symptoms persist or the diagnosis is unclear.
Investigations & Imaging
- Ultrasound
- May show tendon thickening, hypoechoic changes, or neovascularity, although findings do not always correlate with pain.
- MRI
- Used in persistent or severe cases to assess tendon integrity and exclude partial tears or other pathology.
Grading / Classification
- Reactive triceps tendinopathy
- Early stage tendon pain often following a sudden increase in load, with relatively intact tendon structure.
- Degenerative triceps tendinopathy
- Long-standing symptoms associated with reduced tendon load tolerance and structural tendon changes.
Physiotherapy Management
Physiotherapy for triceps tendinopathy focuses on restoring the tendon’s ability to tolerate load while addressing contributing factors such as technique, strength deficits, and training errors.
Treatment is individualised and progressive, aiming to reduce pain while maintaining as much activity as safely possible rather than complete rest.
Exercise
Physiotherapy exercises form the core of rehabilitation. Programs typically begin with isometric or low-load strengthening to reduce pain and maintain muscle activation.
Exercises then progress to slow, controlled resistance training for the triceps, gradually increasing load and range as tolerance improves. Eventually, faster and more functional movements are introduced to prepare for sport or work-specific demands.
Activity Modification
Activity modification involves reducing or temporarily adjusting aggravating activities rather than avoiding all upper limb use. This may include altering training volume, modifying exercises, or changing technique.
Manual Therapy
Manual therapy may be used to address soft tissue restrictions or joint stiffness in the elbow, shoulder, or thoracic spine that contribute to altered loading patterns.
Heat & Ice
Ice may help manage pain after heavy loading, while heat may assist with muscle stiffness when appropriate.
Education
Education is critical so patients understand tendon loading principles, expected recovery timelines, and the importance of gradual progression.
Other
Other strategies may include taping, temporary bracing, and programming advice for gym or sport participation.
Other Treatments
Other treatments may include short-term pain relief as advised by a doctor. Injection therapies are generally not first-line and should be considered cautiously.
Surgery
Surgery is rarely required for triceps tendinopathy and is only considered in severe, refractory cases or when there is a significant partial or complete tendon rupture.
Prognosis & Return to Activity
The prognosis for triceps tendinopathy is generally good with appropriate physiotherapy and load management. Most people improve over weeks to months depending on symptom duration and adherence to rehabilitation.
Long-term outcomes are best when individuals complete a progressive strengthening program and address contributing factors rather than relying on passive treatments alone.
Complications
- Persistent pain if tendon loading is not appropriately modified.
- Reduced pushing or throwing performance.
- Progression to partial tendon tearing in rare cases.
Preventing Recurrence
- Gradually progress training loads and avoid sudden spikes in intensity.
- Maintain shoulder and trunk strength to reduce elbow overload.
- Address early elbow pain with physiotherapy before it becomes persistent.
When to See a Physio
- You have persistent pain at the back of the elbow with pushing or lifting.
- Your elbow pain is limiting gym training, sport, or work.
- Symptoms are not improving despite rest or activity modification.
