Treatment for a supraspinatus tear depends on the size of the tear, your age, your activity level, and how much it affects your daily life. Most partial tears respond well to physical therapy and targeted injections, while full-thickness tears larger than 15 mm or those caused by acute trauma are more likely to need surgical repair. Here’s what each treatment path looks like and what to expect from recovery.
How Tears Are Classified
Supraspinatus tears are categorized by their depth and location. A partial tear means some fibers are torn but the tendon isn’t completely severed. A full-thickness tear goes all the way through. Partial tears are further graded by how deep they penetrate: Grade 1 tears are less than 3 mm deep, Grade 2 tears measure 3 to 6 mm, and Grade 3 tears involve more than half the tendon’s thickness, generally exceeding 6 mm.
The tear can also sit on different surfaces of the tendon. Articular-side tears face the joint, bursal-side tears face the space above the tendon, and intratendinous tears are buried within the tendon itself. Your doctor will typically use an MRI to determine the tear’s size, location, and depth, all of which shape the treatment plan.
When Conservative Treatment Is Enough
Physical therapy is the first line of treatment for partial tears and smaller full-thickness tears. Full-thickness tears up to 15 mm with healthy surrounding muscle and an intact front edge of the tendon carry a relatively low short-term risk of getting worse. That gives you time to try conservative treatment without compromising the results of surgery if you end up needing it later.
A typical rehab program starts with gentle range-of-motion work to reduce stiffness and pain, then gradually adds strengthening exercises for the rotator cuff and the muscles that stabilize the shoulder blade. Your therapist will progress you through phases, from passive movement (where they move your arm for you) to active exercises and eventually resistance training with bands or light weights. Most conservative programs run 8 to 12 weeks before reassessing whether surgery is needed.
During recovery, avoid movements that load the tendon in vulnerable positions. Overhead pressing, lateral raises with heavy weight, upright rows, and any exercise that causes pain should be dropped. In daily life, reaching behind your back, lifting heavy objects away from your body, and sleeping on the affected side tend to aggravate the tear. Pain during an exercise is a clear signal to stop, not push through.
Injections for Pain and Healing
When physical therapy alone isn’t controlling pain well enough to make progress, injections can help. The two most common options are corticosteroid injections and platelet-rich plasma (PRP).
Corticosteroid shots reduce inflammation quickly. At one month, patients with partial supraspinatus tears report similar pain relief and functional improvement whether they receive a steroid injection or PRP. The difference emerges over time. A study published in the Orthopaedic Journal of Sports Medicine found that at six months, PRP patients continued to improve while the steroid group plateaued. Pain scores in the PRP group were less than half those in the steroid group at the six-month mark, and shoulder function scores were significantly better.
This makes steroids a reasonable short-term option if you need quick relief to participate in therapy, but PRP may offer better durability for partial tears. PRP uses a concentrated sample of your own blood platelets, which release growth factors that support tendon healing. It’s worth noting that PRP is not always covered by insurance.
When Surgery Becomes Necessary
Surgery is generally recommended for acute traumatic tears (especially those 15 mm or larger in a previously healthy shoulder), full-thickness tears that haven’t improved after several months of conservative care, and tears with disruption of the front portion of the supraspinatus tendon. Younger, active patients and those who need overhead arm use for work or sport are also more likely to benefit from early repair.
The two main surgical approaches are arthroscopic repair and open repair. Arthroscopic surgery uses small incisions and a camera, causing less tissue disruption. It generally means shorter hospital stays, lower infection rates, and faster early recovery. Open repair provides the surgeon with better direct visualization and structural support, which can benefit patients with large or complex tears. Despite these differences in the early months, long-term outcomes for pain relief, function, and retear rates are similar between the two approaches for most patients. Arthroscopic repair has become the more popular choice.
Post-Surgery Recovery Timeline
Recovery after supraspinatus repair follows a predictable but slow timeline. Expect to wear a sling with a small pillow for six weeks. You won’t be able to drive during this period.
Passive range of motion, where a therapist moves your arm while your muscles stay relaxed, begins within seven days of surgery. For the first four weeks, this is the only type of movement allowed. The goal is to prevent the joint from stiffening while protecting the repair.
Between weeks 8 and 12, you’ll transition to moving the arm under your own power. Gentle isometric strengthening, where you contract the muscles without moving the joint, starts around week 8. Resistance exercises with bands or light weights begin at week 12. From there, rehabilitation progresses toward sport-specific or activity-specific training over the following months.
Full recovery typically takes 6 to 12 months depending on the tear size, repair quality, and how consistently you follow the rehab protocol. Rushing any phase increases the risk of retear.
Retear Risk by Age
Retears are a real concern after surgical repair. A study of 1,600 consecutive rotator cuff repairs found a clear relationship between age and retear rates. Patients under 50 had a retear rate of just 5%. That climbed to 10% for patients in their 50s and 15% for those in their 60s. The jump gets steeper after 70: patients in their 70s had a 25% retear rate, and those 80 and older reached 34%.
Age was an independent risk factor, meaning it predicted retears regardless of other variables. The practical takeaway: if you’re younger, surgical repair has excellent durability. If you’re older, the decision to operate should weigh the higher retear risk against how much the tear limits your daily function.
Returning to Sports and Full Activity
Clearance for sports requires more than just time on the calendar. The criteria used most often include full or near-full pain-free range of motion, restored shoulder strength (particularly the ratio of outward to inward rotation strength), and successful completion of a sport-specific training progression.
For overhead athletes like tennis players or baseball pitchers, full range of motion is essential before returning. Collision sport athletes may not need every last degree of motion but do need solid strength and stability. Pitchers typically complete a structured interval throwing program, progressing from flat-ground tosses to throwing from the mound, before being cleared for competition.
Proprioception, your shoulder’s ability to sense its own position and react to unexpected forces, is another factor therapists assess. A shoulder that’s strong but slow to stabilize under load isn’t ready for contact or high-speed overhead movements.
Biologic Augmentation
Newer approaches aim to boost tendon healing at the time of surgery. These include PRP and bone marrow concentrate applied directly to the repair site, as well as scaffold patches that provide a structural framework for new tissue growth. Early results across these strategies are promising, but study methods vary widely and no standardized guidelines exist yet for when or how to use them. Your surgeon may offer biologic augmentation as an add-on to standard repair, particularly for larger tears or patients at higher retear risk, but it remains an evolving area rather than a proven standard of care.
