| Abstract | Background: During hip arthroscopy, managing concomitant cartilage damage and chondrolabral junction breakdown remains an ongoing challenge for orthopaedic surgeons, as previous studies have associated such lesions with inferior postoperative outcomes Description: After induction of anesthesia and appropriate patient positioning, a quadrilateral arrangement of arthroscopic portals is established to perform puncture capsulotomy Alternatives: Currently, strategies to address acetabular cartilage lesions may include microfracture, autologous chondrocyte implantation, matrix-induced autologous chondrocyte implantation, autologous matrix-induced chondrogenesis, osteochondral allografts, and orthobiologics Rationale: This versatile and updated technique is a safe and reproducible method for BMAC harvesting, processing, and application that avoids donor-site morbidity, obtains a substantial concentration of CTP cells, minimizes additional operative time, and limits the hip arthroscopy and aspiration to a single procedure Expected outcomes: Patients with moderate cartilage damage treated with BMAC at the time of labral repair experienced significantly greater improvements in functional outcomes at 12 and 24 months postoperatively compared with similar patients without BMAC augmentation Important tips: Utilize the previously established Dienst arthroscopic portal for the bone marrow aspiration in order to avoid secondary donor site morbidity.Under fluoroscopic guidance, approach the ilium along the coronal plane, aiming toward the anterior superior iliac spine.With a heparin-rinsed Jamshidi bone marrow biopsy needle, penetrate the lateral cortex of the ilium just proximal to the sourcil in order to consistently harvest a total combined bone marrow aspirate/ACD-A volume of approximately 120 mL.Simultaneously perform the bone marrow aspirate and whole venous blood centrifugation during the hip arthroscopy procedure in order to minimize additional operative time.Bone marrow aspiration should be performed without applied traction in order to minimize the risk of neurovascular complications associated with extended traction time.
