Biceps Tenodesis vs. Tenotomy: What the Difference Means for Your Shoulder

When the long head of the biceps tendon is damaged, inflamed, or torn, two surgical options are commonly considered: biceps tenodesis and biceps tenotomy. Both procedures address the same underlying problem, a tendon that is no longer functioning normally at its attachment point inside the shoulder. But they approach the solution differently, and the choice between them has real consequences for recovery, cosmetic outcome, and long-term function.

Biceps tenodesis vs. tenotomy is one of the more nuanced decision points in shoulder surgery. The right answer depends on who the patient is, what they need from their shoulder, and what other procedures are being performed at the same time. Understanding the difference between these two options, and the factors that drive the decision, helps patients engage more effectively in that conversation with their surgeon.

Proximal biceps pathology is frequently encountered alongside rotator cuff tears, shoulder impingement, and labral disease.

The Role of the Long Head of the Biceps Tendon

The biceps muscle has two heads at its proximal end. The short head attaches to the coracoid process of the scapula and is rarely involved in shoulder pathology. The long head follows a more complex path, originating at the superior glenoid labrum and the supraglenoid tubercle, running through the bicipital groove on the front of the humerus, and then exiting the shoulder joint.

This intra-articular course makes the long head of the biceps tendon uniquely vulnerable. It is subjected to repetitive mechanical stress within the bicipital groove, is commonly involved in impingement and rotator cuff disease, and serves as the attachment site for SLAP lesions when the superior labrum is torn. Tendon degeneration, partial tearing, instability within the groove, and frank rupture are all common presentations in orthopedic practice.

The long head contributes modestly to elbow flexion strength and is a more significant contributor to forearm supination. Its role in shoulder mechanics is less clearly defined, though it appears to function as a secondary stabilizer of the glenohumeral joint in certain positions. When it becomes a consistent pain generator that does not respond to conservative management, surgical treatment of the tendon itself becomes the focus.

What Each Procedure Does

Biceps Tenotomy

Biceps tenotomy is the simpler of the two procedures. The long head of the biceps tendon is released from its attachment at the superior glenoid labrum inside the shoulder joint. Once released, the tendon retracts distally into the arm, where it eventually scars down within the bicipital groove or surrounding soft tissue.

The procedure eliminates the tendon as a source of intra-articular pain and inflammation. Because there is no reattachment step, it adds minimal time and complexity to the overall surgical case, which is an important consideration when it is performed alongside a rotator cuff repair or other shoulder procedure. The technical execution is straightforward, the recovery from the tenotomy itself is uncomplicated, and the pain relief is generally reliable.

The trade-off is that the tendon is no longer anchored at its normal resting length. In a proportion of patients, the retracted muscle belly creates a visible deformity in the arm, a bulge toward the elbow known as a Popeye deformity. Some patients, particularly those who are lean and physically active, also develop cramping in the biceps with exertion. Not every patient who undergoes tenotomy develops these findings, but the risk exists and must be discussed before the procedure.

Biceps Tenodesis

Biceps tenodesis also begins with releasing the tendon from its superior labral attachment inside the joint. The difference is what happens next. Rather than allowing the tendon to retract freely, the surgeon reattaches it at a new fixation point on the humerus, typically in the bicipital groove or just below it. This reattachment is secured using a variety of techniques, including suture anchors, interference screws, or cortical button fixation, depending on the surgeon's preference and the specific anatomy encountered.

By fixing the tendon at a controlled length, tenodesis preserves the muscle's resting length-tension relationship. This means the biceps continues to function closer to its normal mechanical state, with better preservation of supination strength and elbow flexion power compared to tenotomy. The risk of Popeye deformity is essentially eliminated, and cramping complaints are less common.

The procedure is more technically demanding than tenotomy and adds operating time when combined with other shoulder procedures. The fixation site must heal before the tendon is subjected to loading, which creates a more structured and somewhat longer recovery period. For patients undergoing shoulder surgery at this practice, the full range of arthroscopic and open shoulder procedures is approached with the same evidence-based framework that governs every treatment decision.

Who Is a Candidate for Each Procedure

Candidacy for biceps tenodesis versus tenotomy is not determined by a single variable. The decision reflects a combination of patient-specific factors that collectively point toward one option or the other.

Candidates for Biceps Tenotomy

Tenotomy is generally appropriate for patients whose profile prioritizes simplicity and a shorter recovery over maximal functional preservation. Specific characteristics that support a tenotomy approach include:

• Older age, typically above 60 to 65, though this is not an absolute threshold
• Low physical demand and sedentary or lightly active lifestyle
• Limited concern about cosmetic appearance of the arm
• Significant medical comorbidities that favor a shorter operative time
• Concurrent shoulder procedures where added operative complexity is a meaningful concern

It is worth noting that age alone does not determine the right choice. A 70-year-old who performs physical labor, competes in masters athletics, or places high value on the appearance of their arm may be a better tenodesis candidate than a 55-year-old with a sedentary lifestyle and low functional expectations. The conversation should always center on what the individual patient needs.

Candidates for Biceps Tenodesis

Tenodesis is generally preferred for patients where preserving biceps function and appearance matters more. Characteristics that support tenodesis include:

• Younger age, typically under 60, with a longer expected active lifespan
• Manual laborers, construction workers, or patients with physically demanding occupations
• Competitive or recreational athletes who depend on forearm supination and biceps strength
• Patients with strong cosmetic concerns about the appearance of their arm
• Thin or lean body habitus where a Popeye deformity would be particularly visible

The American Shoulder and Elbow Surgeons, a professional society to which Dr. Burrus belongs, has published guidance on biceps tendon treatment that supports this patient-stratified approach to decision-making.

Functional Differences Between Tenodesis and Tenotomy

The functional consequences of these two procedures have been studied directly, and the results inform how surgeons counsel patients about what to expect from each approach.

Forearm supination is the movement most affected by the choice between these procedures. The long head of the biceps is a primary supinator of the forearm, and its resting length determines how efficiently it generates supination force. Studies comparing tenodesis to tenotomy have consistently demonstrated that tenotomy is associated with greater supination strength deficits compared to the contralateral arm. These deficits are typically modest in absolute terms, and most low-demand patients do not notice them in daily life.

For patients whose work or sport relies on repeated supination movements, however, the functional difference is clinically meaningful. Plumbers, electricians, surgeons, and athletes who throw or perform overhead movements regularly may experience these deficits as real limitations. Tenodesis largely preserves supination strength because the tendon is anchored at its appropriate length rather than allowed to retract.

Elbow flexion strength is less affected by either procedure, as the short head of the biceps and the brachialis muscle contribute substantially to flexion and are unaffected by either tenotomy or tenodesis. Cramping with exertion is reported by a subset of patients following tenotomy, particularly those who are physically active. This symptom is thought to result from the altered mechanics of the retracted tendon and is less commonly reported following tenodesis. Research published in the National Library of Medicine has examined functional outcomes across both procedures and supports the pattern of better strength preservation with tenodesis in active patient populations.

Recovery Comparison: Tenodesis vs. Tenotomy

Recovery from these two procedures differs in both structure and duration, which is a practical consideration for patients planning around their work, family, and activity commitments.

Recovery After Biceps Tenotomy

Because tenotomy does not create a repair that requires biological healing, the recovery is primarily limited by what other procedures were performed at the same time. If tenotomy is performed as a standalone procedure, most patients regain comfortable use of the arm relatively quickly. There are no structural restrictions on loading the biceps once the surgical incision is healed, and patients typically resume light activities within a few weeks.

When tenotomy accompanies a rotator cuff repair, the recovery timeline is governed by the cuff repair rather than the tenotomy. Patients should not expect the tenotomy itself to prolong their recovery in most circumstances. The absence of a healing constraint is one of the reasons tenotomy is appealing in older patients who are already managing a longer recovery from concurrent shoulder work.

Recovery After Biceps Tenodesis

Tenodesis requires the reattached tendon to heal at its new fixation site before it can be loaded. This biological healing process takes time, and the recovery protocol reflects that requirement. During the initial six to twelve weeks following surgery, loading the biceps with significant force is restricted to protect the fixation. Patients are typically advised to avoid heavy lifting, strong elbow flexion against resistance, and forceful supination movements during this period.

Formal physical therapy follows the initial protected phase, with progressive strengthening introduced as healing advances. Most patients undergoing isolated biceps tenodesis achieve full, unrestricted use of the arm by four to six months postoperatively. Athletes and manual laborers returning to high-demand activity may require closer to six months before they are cleared for full loading.

The longer and more structured recovery of tenodesis is a real consideration for patients who cannot accommodate restrictions on lifting or arm use for occupational or family reasons. This practical factor sometimes influences the decision in favor of tenotomy even in patients who would otherwise be good tenodesis candidates.

How Surgeon Preference and Patient Age Influence the Decision

Surgeon experience and training play a role in biceps tendon treatment decisions that deserves honest acknowledgment. Both procedures are well-established and supported by outcome data, but they require different technical skills and add different degrees of complexity to a shoulder case. A surgeon who performs high volumes of shoulder arthroscopy and has extensive experience with tenodesis fixation techniques will approach the decision differently than one who performs shoulder surgery less frequently.

Tenodesis can be performed arthroscopically, open, or through a mini-open approach, and the fixation technique varies between interference screw, suture anchor, and cortical button constructs. Each approach has specific anatomical and biomechanical considerations. The choice of technique affects both the security of fixation and the demands placed on the patient during recovery. A surgeon's familiarity with a specific technique is a legitimate factor in what they are able to offer and what they are likely to recommend.

Patient age influences the decision through several intersecting factors. Younger patients have more years ahead of physically demanding activity, which makes the preservation of function and the avoidance of Popeye deformity more consequential. They also have better tissue quality and healing capacity, which supports the biological demands of tenodesis. Older patients are more likely to have concurrent rotator cuff disease, medical comorbidities, and lower functional expectations, all of which tend to favor the simpler, lower-risk approach of tenotomy.

Published outcome data consistently shows that both procedures produce good pain relief. The divergence in outcomes relates primarily to strength preservation, cosmetic results, and the rate of cramping complaints, all of which favor tenodesis in active and younger patient populations. For patients consulting with  M. Tyrrell Burrus, MD, the recommendation reflects a thorough assessment of these variables against the current evidence, without defaulting to a single approach for all patients.

Making the Right Choice for Your Shoulder

The decision between biceps tenodesis and tenotomy is not one that should be made on the basis of a general rule. Both procedures are appropriate treatments in the right clinical context, and the relevant question is not which one is better in the abstract but which one is better for the specific patient in front of the surgeon.

Patients preparing for this conversation should think carefully about their functional demands, their tolerance for a longer and more restricted recovery, and how much they care about the cosmetic appearance of their arm. They should also ask their surgeon how the biceps tendon procedure fits into the overall plan for their shoulder, particularly if a rotator cuff repair or other work is being performed at the same time.

The right clinical consultation will cover all of these variables clearly and give patients a genuine understanding of what each option involves and what outcomes they can reasonably expect.

Frequently Asked Questions

What is the difference between biceps tenodesis and tenotomy?

Biceps tenotomy releases the long head of the biceps tendon from its attachment at the superior glenoid labrum, allowing it to retract and scar down in the arm. Biceps tenodesis also releases the tendon from its labral attachment but then reattaches it at a new fixation point lower on the humerus, preserving its resting length and function. Tenotomy is a simpler procedure with a faster recovery. Tenodesis is more technically demanding but better preserves biceps strength, contour, and reduces the risk of a Popeye deformity.

Who is a good candidate for biceps tenotomy?

Biceps tenotomy is generally appropriate for older, less active patients who prioritize a shorter recovery and simpler procedure over cosmetic appearance or maximal functional preservation. It is also reasonable for patients with significant medical comorbidities, low physical demand, and those who are unlikely to notice or be bothered by a Popeye deformity. Age alone does not determine candidacy. The patient's functional goals and activity level are equally important.

Who is a good candidate for biceps tenodesis?

Biceps tenodesis is generally preferred for younger, more active patients, patients who perform manual labor or heavy overhead activities, those who are cosmetically concerned about a Popeye deformity, and athletes who depend on biceps strength for performance. Tenodesis better preserves the length-tension relationship of the biceps and reduces the risk of deformity and cramping that can follow tenotomy in active individuals.

What is a Popeye deformity and when does it occur?

A Popeye deformity is a visible cosmetic change in the upper arm that occurs when the long head of the biceps tendon retracts distally after release. The muscle belly bunches toward the elbow rather than distributing normally along the arm, creating a visible bulge. It occurs after biceps tenotomy and also after spontaneous tendon ruptures. It is primarily cosmetic but can be accompanied by cramping and mild supination weakness in some patients.

Does biceps tenodesis affect strength compared to tenotomy?

Biceps tenodesis better preserves the resting length of the biceps muscle, which is important for maintaining the strength of forearm supination and elbow flexion. Studies comparing the two procedures show that tenodesis results in less supination weakness and fewer complaints of cramping. For patients with high functional demands, this difference is clinically meaningful. For low-demand patients, the functional difference between the two is generally modest.

How long is recovery after biceps tenodesis vs. tenotomy?

Tenotomy has a shorter and less restrictive recovery. There are no structural healing requirements, so patients can begin motion and activity earlier. Most patients achieve comfortable use of the arm within a few weeks. Tenodesis requires the reattached tendon to heal at its new fixation site, which typically takes six to twelve weeks. Lifting restrictions are enforced during this period to protect the repair. Full return to unrestricted activity after tenodesis typically occurs around four to six months postoperatively.

How does a surgeon decide between biceps tenodesis and tenotomy?

The decision integrates patient age, activity level, functional demands, cosmetic concerns, and the clinical context in which the procedure is being performed. Younger, active, and higher-demand patients generally benefit more from tenodesis. Older, lower-demand patients with comorbidities are often better served by tenotomy. The procedure is also influenced by what other shoulder surgery is being performed at the same time, since tenodesis adds time and technical complexity to the overall case.

A Note From M. Tyrrell Burrus, MD

Biceps tendon pathology is something I encounter regularly in shoulder surgery, and the tenodesis versus tenotomy decision is one I take seriously rather than defaulting to a single approach across all patients. The procedure matters, but so does the fit between the procedure and the person.

In my practice, older patients with low functional demands and significant concurrent shoulder disease often do very well with tenotomy. The pain relief is reliable, the recovery is straightforward, and the functional and cosmetic trade-offs are ones they can genuinely live with. For younger patients, manual workers, and athletes, tenodesis is almost always the right choice because the functional and cosmetic consequences of tenotomy become meaningful over a longer time horizon.

What I find most important in this conversation is honesty about what each option actually involves. Tenotomy is not a lesser procedure for patients who are appropriate candidates, and tenodesis is not automatically superior just because it is more technically demanding. The best outcome for any patient comes from matching the procedure to the person, not from applying a blanket preference.

If you have been told you need biceps tendon surgery, or if you have ongoing anterior shoulder or biceps groove pain that has not responded to conservative treatment, I encourage you to seek an evaluation that addresses both the tendon and the broader shoulder picture together. Isolated treatment of the biceps without understanding the full shoulder anatomy rarely produces the best result. Request an appointment now.
