Arthroscopic rotator cuff repair is a minimally invasive surgical technique that uses a small camera and specialized instruments inserted through narrow portals to reattach a torn rotator cuff tendon to bone. Arthroscopic repair is commonly used for repairable rotator cuff tears and allows the surgeon to evaluate and repair the tendon through small portals rather than the larger incision used in traditional open surgery.

Michael J. Bercik Jr., MD, a board-certified orthopedic surgeon and fellowship-trained shoulder specialist, performs arthroscopic rotator cuff repair for patients with tears that have not responded to conservative care or that are unlikely to do so based on tear size and patient factors. Every surgical plan is individualized based on MRI findings, tendon quality, and the patient’s functional goals.

How Arthroscopic Repair Differs from Open and Mini-Open Techniques

Three surgical approaches have been used for rotator cuff repair: open, mini-open, and fully arthroscopic. Understanding the differences helps patients make sense of their options and why the arthroscopic technique is preferred in most cases today.

Open Rotator Cuff Repair

Open repair was the original surgical approach for rotator cuff tears. It involves a larger incision at the top of the shoulder, detachment of the deltoid muscle from its bony origin to expose the rotator cuff, direct visualization of the tear, and repair of the tendon under direct sight. Open repair is still appropriate in certain complex cases, such as some revision situations or tears with significant bone loss, but it carries greater tissue disruption, a longer recovery from deltoid healing, and a higher risk of post-operative stiffness compared to less invasive approaches.

Mini-Open Repair

Mini-open repair was developed as a transitional technique that combines initial arthroscopic inspection of the shoulder with a small open incision through which the actual tendon repair is performed. The deltoid is typically split rather than detached, reducing some of the morbidity of the traditional open approach. Mini-open repair remains a reasonable option for specific tear patterns but has been largely replaced by fully arthroscopic techniques in the hands of experienced shoulder surgeons.

Fully Arthroscopic Repair

Fully arthroscopic repair avoids any large incision or deltoid disruption. The entire procedure, from inspection to tendon preparation to anchor placement to final suture fixation, is performed through portals typically less than one centimeter in diameter. A high-definition camera transmits a magnified view of the shoulder interior to a monitor, allowing complete visualization of the tear, the surrounding joint, and all relevant structures before and throughout the repair. The deltoid is not cut or detached at any point. This preserves the integrity of the muscle that is most important for overall shoulder function and contributes meaningfully to the advantages the arthroscopic approach provides in recovery. 

Repair Constructs: Single-Row, Double-Row, and Transosseous-Equivalent

One of the more technically significant decisions in arthroscopic rotator cuff repair is the configuration of suture anchors used to fix the tendon back to bone. The goal is to recreate as much of the native tendon footprint as possible while achieving mechanically secure fixation that holds through the early weeks of healing, when the biological attachment is still forming.

Single-Row Repair

Single-row repair places a line of suture anchors along the medial aspect of the greater tuberosity footprint. Sutures are passed through the tendon and tied to compress the tendon edge against bone. Single-row repair is technically simpler and appropriate for smaller, well-defined tears where the tendon has adequate thickness and mobility. It produces reliable outcomes in the right tear pattern and remains a valid option when double-row fixation is not indicated or feasible.

Double-Row Repair

Double-row repair uses both a medial and a lateral row of anchors to restore a larger portion of the native tendon footprint on the humeral head. The additional lateral fixation increases the area of tendon-to-bone contact, distributes load more evenly across the repair interface, and produces stronger initial fixation in biomechanical testing compared to single-row constructs. Footprint restoration is an important factor in achieving reliable tendon healing after repair. For larger tears with adequate tendon tissue quality, Dr. Bercik typically uses a double-row construct to maximize footprint contact and mechanical stability.

Transosseous-Equivalent (Suture Bridge) Repair

The transosseous-equivalent technique, also called a suture bridge repair, extends the double-row concept further by passing sutures from medial anchors through the tendon and then fixing them to lateral anchors without tying additional knots at the tendon surface. This creates a compression pattern across the entire footprint that distributes load more uniformly and eliminates the pressure points that knotted sutures can create at the tendon. The result is a repair with high initial fixation strength and broad contact area that closely resembles the mechanical behavior of a traditional transosseous bone tunnel repair. Transosseous-equivalent constructs are used for larger tears when tendon tissue allows adequate suture passage and the footprint width warrants the additional complexity.

Anchor Choices and Biologic Augmentation

Suture anchors are available in a range of materials, including titanium, PEEK (polyetheretherketone), and fully bioabsorbable compositions. The choice of anchor material and diameter is influenced by bone quality, anchor placement site, and surgeon preference. In patients with softer bone, such as older patients with osteopenia, anchor selection and placement technique are adjusted to maintain adequate fixation strength.

Biologic augmentation refers to the use of adjunctive materials at the repair site intended to support the healing environment. Options include platelet-rich plasma (PRP) and various biological scaffolds placed at the tendon-bone interface. 

What the Day of Arthroscopic Rotator Cuff Repair Looks Like

Patients preparing for arthroscopic rotator cuff repair often want to know what to expect from the moment they arrive through discharge. Understanding the sequence of events reduces uncertainty and helps patients prepare practically for the day.

Pre-Operative Preparation and Nerve Block

Patients arrive at the surgical facility and complete standard pre-operative check-in, including nursing assessment, IV placement, and a review of the surgical plan with Dr. Bercik and the anesthesia team. Most patients undergoing arthroscopic rotator cuff repair receive a regional nerve block, specifically an interscalene brachial plexus block, administered by the anesthesiologist before entering the operating room. The nerve block temporarily numbs the shoulder and arm and serves as the primary post-operative pain management tool for the first twelve to twenty-four hours after surgery, substantially reducing the need for opioid pain medication during that period.

General anesthesia is used for the procedure itself. Patients are asleep throughout the operation and are not aware of any portion of the surgical process.

Patient Positioning

Dr. Bercik positions the patient in either the beach chair position, which places the patient in a semi-seated upright posture, or the lateral decubitus position, which places the patient on their side with the operative arm suspended in traction. The choice of position reflects the specific tear pattern and the surgeon’s preferred approach for that case. Both positions provide adequate access to all shoulder structures for arthroscopic repair.

Arthroscopic Inspection and Repair

Once positioned, three to four small portals are created around the shoulder. The arthroscope is introduced first, providing complete visualization of the glenohumeral joint and the subacromial space. Dr. Bercik inspects the full extent of the tear, evaluates the quality of the tendon edge, assesses the biceps tendon and labrum, and examines the articular cartilage before beginning the repair. Any concurrent pathology identified, such as a biceps tendon problem or significant subacromial bone spur, is addressed at the same time.

Operative Time and Discharge

Most arthroscopic rotator cuff repairs take between sixty and ninety minutes. Cases with larger or more complex tears, or where concurrent procedures are performed, may extend to approximately two hours. The procedure is outpatient in the large majority of cases, meaning patients recover briefly in the post-anesthesia care unit and go home the same day. Overnight admission is uncommon and reserved for patients with medical conditions that require post-operative monitoring. A responsible adult must be available to drive the patient home and stay with them the first night.

Advantages of the Arthroscopic Approach

The shift toward fully arthroscopic rotator cuff repair in experienced hands reflects several consistent advantages over open techniques that are supported by clinical outcomes data.

Reduced post-operative pain. Because the deltoid is not cut or detached and the incisions are small, tissue disruption is significantly less than with open repair. Most patients experience manageable pain in the first days after surgery, particularly with the support of the nerve block, and transition to oral anti-inflammatory medications and ice within the first week.

Better cosmetic results. Portal incisions are small and typically heal with minimal scarring. Patients concerned about visible scarring, particularly those who wear sleeveless clothing or participate in activities where the shoulder is exposed, consistently prefer the cosmetic outcome of arthroscopic repair.

Lower infection risk. Smaller incisions reduce wound surface area and the risk of superficial or deep wound infection. Surgical site infection following arthroscopic shoulder surgery is uncommon. Minimally invasive approaches to shoulder surgery are associated with lower rates of wound complications compared to traditional open techniques.

Full joint inspection. The arthroscope provides a panoramic view of the shoulder that is not available through a standard open incision. Concurrent pathology inside the joint, including labral tears, articular cartilage damage, and biceps tendon abnormalities, can be identified and addressed in the same operative setting rather than discovered only if symptomatic after surgery.

Preservation of the deltoid. Avoiding deltoid detachment eliminates one of the primary sources of morbidity associated with open repair and preserves the muscle that is most important for overall shoulder function, especially in cases where rotator cuff healing may be incomplete.

Who Is Not a Candidate for Arthroscopic Rotator Cuff Repair?

Arthroscopic repair is appropriate for most patients with repairable rotator cuff tears, but it is not the right approach for everyone. Dr. Bercik evaluates candidacy individually, and certain findings on examination or imaging may indicate that a different approach or a different procedure altogether is more appropriate.

Patients who may not be suitable candidates for arthroscopic repair include:

  • Irreparable tears with severe tendon retraction, advanced Goutallier grade 3 or 4 fatty atrophy, or tissue quality that cannot support suture fixation. In these cases, superior capsular reconstruction, tendon transfer, or reverse shoulder replacement may be a more appropriate conversation.
  • Significant glenohumeral arthritis present alongside the rotator cuff tear. When cartilage damage is advanced, biological reconstruction of the cuff is unlikely to produce satisfactory outcomes, and a joint replacement-based approach warrants consideration.
  • Prior failed repairs with substantial scar tissue and altered tissue planes that make arthroscopic access and repair technically unreliable. Some revision cases benefit from a more open approach to allow adequate tendon mobilization and anchor fixation.
  • Medical conditions that significantly increase the risk of general anesthesia or prolonged surgical positioning, which are evaluated pre-operatively in consultation with the patient’s primary care physician or relevant specialist.

Patients who fall outside the candidacy criteria for arthroscopic repair are not turned away. The full range of shoulder services at Lancaster Shoulder includes alternative procedures for patients whose tear characteristics require a different surgical approach. Understanding the full picture of rotator cuff tears, including what makes a tear repairable or not, helps frame these discussions.

Sling Protocol and Phased Rehabilitation After Arthroscopic Repair

Post-operative rehabilitation after arthroscopic rotator cuff repair is phased according to the biology of tendon-to-bone healing rather than how the shoulder feels. The repaired tendon undergoes an inflammatory phase, a proliferative phase during which new tissue forms at the attachment site, and a remodeling phase during which that tissue matures and gains mechanical strength. Understanding that the repair is most vulnerable during the first six to twelve weeks, regardless of pain level, is one of the most important concepts for patients to internalize.

Sling Use and Early Protection (Weeks 1 to 6)

The arm is kept in an abduction sling for the first four to six weeks, with the exact duration based on tear size and the repair construct used. Larger repairs require a longer protective period. The sling holds the arm in a position that reduces tension across the healing tendon attachment and protects the repair from forces generated by active shoulder muscle contraction.

Early Active Motion (Weeks 6 to 12)

As sling use is discontinued, active-assisted and then fully active range-of-motion exercises are introduced under physical therapy guidance. Goals during this phase include restoration of forward elevation, external rotation, and internal rotation through progressive, controlled movement. Scapular stabilization and postural correction exercises are incorporated to support shoulder mechanics during active use.

Dr. Bercik’s rehabilitation protocols, developed in coordination with the physical therapy team, specify the timing and progression of each phase to protect the repair while keeping recovery on track. 

Progressive Strengthening (Months 3 to 6)

Rotator cuff strengthening begins at approximately three months, once clinical and imaging assessment supports adequate healing progression. Elastic resistance, light weights, and functional movement patterns are introduced gradually and advanced based on the patient’s response and strength gains. Overhead reaching, lifting, and sport-specific movements are reintroduced progressively rather than all at once.

Most patients with small to medium tears reach functional daily strength between four and five months post-operatively.

Return to Sport and Full Activity (Months 5 to 12)

Return to sport timelines reflect both tear size and the physical demands of the activity. Recreational athletes with small to medium tears are typically cleared between five and six months. Overhead athletes, including baseball players, swimmers, and tennis players, require more extensive sport-specific rehabilitation and are generally cleared between nine and twelve months. Patients in physically demanding occupations follow a similar timeline and should discuss transitional light-duty needs before surgery so return-to-work planning can begin early.

Frequently Asked Questions

Most arthroscopic rotator cuff repairs use three to four portals, each typically less than one centimeter in diameter. The exact number depends on the tear pattern, whether concurrent procedures are performed, and the surgeon’s preferred technique. The small size and number of portals are a primary reason the procedure causes significantly less tissue disruption than open repair.

In appropriately selected patients, arthroscopic repair achieves equivalent structural outcomes to open repair with less tissue disruption and a more favorable recovery profile. The strength of the repair depends primarily on anchor fixation quality, suture configuration, and tendon tissue quality, not on whether the approach was open or arthroscopic. Double-row and transosseous-equivalent constructs performed arthroscopically can match or exceed the biomechanical properties of traditional open repair in properly selected tear patterns.

Yes. Arthroscopic rotator cuff repair is performed under general anesthesia. Most patients also receive a regional nerve block before surgery to manage post-operative pain during the first twelve to twenty-four hours, which reduces reliance on opioid medications during the most uncomfortable phase of recovery.

Patients are typically instructed to keep the portal sites dry for the first five to seven days after surgery, after which showering is usually permitted with appropriate wound precautions. Specific instructions regarding dressing changes, wound care, and when to remove waterproof coverings are provided at discharge and reviewed at the first post-operative visit.

Suture anchors are small devices inserted directly into bone that hold sutures used to secure the tendon to the bone bed. Bone tunnels are channels drilled through the bone through which sutures are passed and tied over a bone bridge on the outer surface. Traditional bone tunnel repair requires open access and a larger incision. The transosseous-equivalent arthroscopic technique recreates the mechanical behavior of bone tunnel repair using suture anchors placed arthroscopically, without requiring the larger incision that true bone tunnels involve.

Bilateral simultaneous shoulder repair is generally not performed. Having both arms immobilized in slings at once creates significant practical limitations for daily function and self-care during recovery. When both shoulders require repair, surgeries are staged, typically with the more symptomatic or functionally limiting side addressed first. The timing of the second surgery is planned based on the recovery progress of the first.

If an arthroscopic repair does not heal or re-tears during recovery, a revision evaluation is the appropriate next step. This includes a thorough clinical examination, updated imaging (often an MRI arthrogram to account for anchor artifact), and a review of the cause of failure before any discussion of further intervention. Revision options range from re-repair to graft augmentation to alternative reconstruction, depending on tissue quality and joint conditions. The possibility of revision and what it would involve is discussed as part of the pre-operative consultation for primary repair.
