Surgical Augmentation
Biologic adjuncts — including PRP and BMAC — applied intraoperatively during arthroscopic procedures to optimize the healing environment at the repair site and support tissue integration.
What It Is / How It Works
Surgical augmentation refers to the intraoperative application of biologic concentrates — most commonly PRP, BMAC, or fibrin clot — at the site of arthroscopic tissue repair. Rather than standalone injection procedures, these biologics are used as adjuncts to enhance the healing environment created by surgical repair itself. This approach is particularly relevant in rotator cuff repair, labral repair, meniscus repair, ACL reconstruction, and cartilage restoration procedures.
PRP and BMAC are prepared on the day of surgery from the patient's own blood or bone marrow. Following arthroscopic repair, the biologic concentrate is applied directly to the repair site — either injected, applied as a gel clot, or used to augment graft preparation. The goal is to accelerate early tissue ingrowth, reduce the risk of re-tear, and support the maturation of the repaired tissue through the critical early healing window.
Who Is a Candidate
Biologic augmentation with PRP, BMAC, or fibrin clot is most often considered for surgical patients whose tissue quality or healing potential may benefit from additional biologic support, including larger or higher-risk rotator cuff repairs, meniscus repairs performed in isolation or alongside ACL reconstruction, labral repairs, and select cartilage restoration procedures. The decision to augment is made intraoperatively or in pre-surgical planning based on tissue quality, tear pattern, patient age, and the specific procedure being performed, rather than as a universal add-on to every surgery.
Patients are generally not offered augmentation if it would meaningfully prolong operative time without a clear anticipated benefit for their specific repair, or if they have contraindications to the underlying harvest procedure itself, such as active infection or a bleeding disorder that complicates bone marrow or blood product collection. Because the evidence for surgical augmentation varies by procedure and biologic type, with some studies showing modest benefit and others showing none, this is discussed candidly as part of the overall surgical plan.
What to Expect
Surgical augmentation is not a standalone visit but a component of the broader operative procedure. If BMAC is used, bone marrow is aspirated from the iliac crest either before or during the same anesthetic episode and processed in the operating room; if PRP is used, blood is drawn and processed shortly before or during surgery. The prepared biologic is then applied directly to the repair site, such as the tendon-bone interface in a rotator cuff repair or the meniscal tear margin, at the time of fixation.
Recovery follows the timeline dictated by the primary surgical procedure itself rather than a separate protocol, since the biologic is intended to support, not replace, the mechanical repair. Patients proceed through the same postoperative bracing, weight-bearing restrictions, and formal physical therapy progression they would otherwise follow for that surgery, with the biologic augmentation considered one component of the overall healing strategy rather than a variable that changes the rehabilitation timeline on its own.
