The long head of the biceps tendon runs through the front of the shoulder and into the joint. When it becomes irritated or worn, it causes pain at the front of the shoulder that can radiate down the upper arm, worse with lifting and overhead activity.
Biceps tendonitis rarely occurs in isolation. It usually accompanies rotator cuff disease, impingement, or a labral (SLAP) problem, so the evaluation looks at the whole shoulder rather than the tendon alone.
Symptoms
Common complaints include:
- Aching pain at the front of the shoulder
- Pain radiating down the front of the upper arm
- Pain with lifting, pulling, or overhead activity
- Tenderness over the tendon at the front of the shoulder
How it is diagnosed
The exam localizes tenderness to the biceps tendon and uses specific tests that load it. Because biceps tendonitis usually travels with other shoulder problems, an ultrasound or MRI evaluates the cuff and labrum as well, which shapes the treatment.
Most biceps tendonitis improves without surgery. Dr. Lee's treatment starts with activity modification, a rotator-cuff and shoulder-blade rehabilitation program, anti-inflammatory measures, and, when needed, a targeted injection such as PRP or corticosteroid depending on what part of the spectrum the tendon is in.
When pain persists, or when the tendon is significantly worn or part of a larger problem, a biceps tenodesis reattaches the tendon outside the joint, which reliably relieves the pain. It is frequently done at the same time as treatment for an associated rotator cuff or labral problem.
Non-surgical treatment
Most patients improve with:
- Activity modification to reduce provocative lifting and overhead loading
- A rotator-cuff and shoulder-blade physical therapy program
- Anti-inflammatory measures
- A targeted corticosteroid injection in selected cases
Surgical treatment
When pain persists or the tendon is significantly worn, a biceps tenodesis reattaches the tendon to the bone outside the joint, which reliably relieves the pain. It is often combined with treatment of a coexisting rotator cuff tear or labral injury.
Recovery timeline
Recovery depends on whether surgery is needed:
- Non-surgicalActivity modification and a therapy program over several weeks, with gradual improvement.
- After tenodesis, weeks 0 to 4Sling to protect the repair for 4-6 weeks, with gentle guided motion.
- After tenodesis, weeks 4 to 12Progressive strengthening and a graded return to lifting and overhead activity.
What patients commonly misunderstand
Two things to understand:
- It rarely travels alone. Biceps tendonitis usually accompanies a rotator cuff or labral problem, so treating only the tendon may miss the larger issue. The evaluation looks at the whole shoulder.
- Tenodesis is reliable. When surgery is needed, reattaching the biceps tendon outside the joint reliably relieves the pain and is often done alongside other shoulder treatment.
