Procedure

The Allograft OATS instrument set facilitates harvesting of large-diameter osteochondral/hyaline cartilage cylinders from allograft bone. The core is made by placing the condyle into the workstation and harvesting with the donor harvester. A 0.5 mm-undersized recipient socket is created using the appropriately sized recipient harvester. The exact depth of the allograft to match the socket is obtained with the depth measurement guide and the allograft is trimmed to the same depth and obliquity. Dilation of the socket results in a line-to-line fit once the donor allograft is inserted into the recipient socket. Final seating of the allograft is achieved with an oversized tamp, resulting in a perfectly flush, press-fit graft that does not require fixation implants.

Allograft OATS® System for Articular Cartilage Restoration

Riley J. Williams III, MD, (New York, NY) provides a cadaveric demonstration of a cartilage restoration procedure using 16 mm precut osteochondral allograft (OCA) cores. Dr. Williams highlights the single-use Allograft OATS® instrumentation to prepare the site for placement of the 16 mm core. Dr. Williams also shows a technique for implanting a second 16 mm OCA core next to the primary repair.

Allograft OATS® Technique Femoral Transplantation Using a Fresh, Precut 16 mm OCA Core

Brian J. Cole, MD, MBA (Chicago, IL), provides a demonstration of the Allograft OATS® instrumentation and disposable kit features and benefits. Several technical pearls are included, as well as an introduction to a new vice workstation and additional accessories provided in the instrument trays.

Advancements in Fresh OCA Techniques and Instrumentation

Brian D. Giordano, MD, (Rochester, NY) outlines 2 different cases and his rationale for using various surgical techniques to treat cartilage defects of the femoral head. In this case presentation, he describes his reasoning for using biocompression screws to refixate the cartilage versus implanting an allograft femoral plug using the allograft OATS® system.

The BioPatella Instrument Set is the new standard for restoration of the articular surface of the patella when presented with oblong cartilage defects involving a significant amount of the patellar articular surface. Through a series of precisely designed cutting instruments, surgeons can replace damaged cartilage with a single, elliptical piece of viable, hyaline cartilage. The BioPatella instruments were designed to match the natural curvature of the patella to resurface the entire functional articular surface. Multiple sizes allow flexibility for the surgeon to adjust to the width and length of the cartilage defect and to ensure proper restoration of the articular surface with a single osteochondral allograft.

BioPatella™ OATS® System

Thomas M. DeBerardino, MD (San Antonio, TX), introduces the BioPatella™ OATS® surgical technique. The BioPatella instruments allow the preparation of oblong osteochondral allografts to treat large articular cartilage defects in the patella.

The BioUni OATS Instrument Set is the new standard for restoration of the articular surface when presented with elongated cartilage defects in the medial femoral condyle. Through a series of precisely designed cutting instruments, surgeons can replace damaged cartilage with a single, elliptical piece of viable, hyaline cartilage.

The BioUni® OATS® surgical technique is the new standard for restoring the articular surface of elongated cartilage defects in the femoral condyle. Through a series of precisely designed cutting instruments, surgeons can replace the damaged cartilage and bone with a single, oblong osteochondral allograft.

Osteochondral Allografts and the BioUni® OATS® Instrumentation

Jack Farr II, MD, (Indianapolis, IN) and Brian Cole, MD, MBA, (Chicago, IL) discuss various treatment options available for medium-sized articular cartilage lesions. Depending on lesion location, patient age and comorbidities, treatment options may range between BioCartilage® Cartilage Extracellular Matrix augmented marrow stimulation, Cartiform®* Viable Osteochondral Allograft and especially in revision procedures, Fresh Osteochondral Allograft. *Cartiform is a registered trademark of Osiris Therapeutics, Inc.

Treatment Options for Medium Articular Cartilage Lesions

Jason M. Scopp, MD, (Salisbury, MD) introduces his preoperative planning and intraoperative techniques when treating complex alignment and articular cartilage indications. By coordinating the surgical case date with the tissue bank prior to the procedure, Dr. Scopp has been able to expand his practice to include fresh osteochondral allografts and offer several joint preservation techniques to his patients, including the iBalance® HTO system and BioUni® OATS® osteochondral allograft instrumentation.

Talus OATS® instrumentation facilitates harvesting of small-diameter hyaline cartilage osteochondral cores from an osteochondral allograft. Through a series of precise steps with dedicated instrumentation, the surgeon can replace damaged articular cartilage defects with healthy, fresh osteochondral tissue core that matches the contour and cartilage morphology of the recipient site. There are few treatment options for patients with large, symptomatic lesions of osteoarticular surfaces in the talus. &nbsp;This technique provides a reliable outcome when restoring articular cartilage.1

Thomas G. Harris, MD, (Pasadena, CA) presents a case in which he treated an osteochondral lesion of the talus with a fresh allograft OATS® plug. Dr. Harris reviews the preoperative planning, intraoperative pearls including mixing with bone marrow concentrate from the Angel® system, as well as the fixation techniques of the osteotomy.

Articular allografts provided through Arthrex® are processed as fresh allografts with viable chondrocytes. These grafts are used in resurfacing procedures in the knee, shoulder, hip, foot and ankle. Arthrex offers numerous fresh, articular allograft types to meet the needs of the patient and surgeon.

Raffy Mirzayan, MD, (Los Angeles, CA) demonstrates an Osteochondral Allograft Transplantation procedure for resurfacing the damaged articular cartilage of the knee utilizing the Allograft OATS® Instrument Set. The set allows for precise cutting and placement of circular dowels to resurface the cartilage with either a single dowel or for the placement of overlapping dowels to cover the defect. The use of a fresh osteochondral allograft allows for restoration of the articular surface with a mature, hyaline cartilage scaffold that contains viable chondrocytes.
