Together, the use of aseptic technique, proprietary cleansing methods and temperature controlled, ultra low-dose irradiation provide a safe, structurally efficient allograft without impacting the integrity of the tissue and reducing potential for case failure.

Read moreSoft tissue allografts processed with < 1.8Mrads with or without chemical processing and non processed grafts did not have a significantly different risk of revision compared to hamstring autografts.

Read more Download PDFIn recent years, the use of biologic materials in orthopedic surgery has increased; these include such materials as allografts, consisting of cadaveric bone, cartilage, and other soft tissues that can be transplanted into a living patient.
Read moreThis publication highlights research spanning over two decades that was responsible for establishing osteochondral allograft (OCA) transplantation as an effective treatment method for cartilage restoration.
Read more Download PDFMeniscal allograft transplantation (MAT) was developed as a means of treating the symptoms of compartmental overload after meniscectomy. Despite more than 20 years of research in this field, many controversies still exist regarding meniscal transplantation.
Read moreOCA transplantation is a successful salvage surgical treatment after cartilage repair procedures.
Read moreOsteochondral allograft (OCA) transplantation has been used as a treatment option for a range of cartilage disorders.OCA transplantation was successful as a salvage treatment procedure for cartilage injuries of the patella.
Read moreOCA transplantation is an appropriate treatment option in both cartilage primary repair and revision injuries. Both groups showed improvements in pain and function, exhibited long survivorship and had high satisfaction rates.
Read moreOsteochondral allograft transplantation is a useful salvage treatment option for reciprocal bipolar cartilage lesions of the knee. High reoperation and failure rates were observed, but patients with surviving allografts showed significant clinical improvement.
Read moreThe meniscus has an important function in protecting the joint surfaces within its compartment whilst facilitating joint lubrication and contributing to stability of the knee. It is now well recognized that meniscal loss leads to degenerative change.
Read moreStatistically different increasing tensile strength was seen as graft diameter increased. Significant variability exists in the strength of multi-stranded hamstring allografts within the diameter range of 6 to 9 mm that often falls well below the commonly accepted value of 4,000 N for a hamstring graft.
Read moreOsteophytes can be observed on the tibial plateau during meniscus allograft transplantation.
Read moreThe aim of this study was to conduct an updated review of the literature regarding the clinical and basic science knowledge on osteochondral allograft transplantation in the knee for the treatment of large defects.
Read moreAllograft tendons are commonly used in surgical ligament reconstruction. While it is commonly accepted that donor age will affect mechanical properties of graft tissue, the apparent age threshold is unknown.
Read moreOsteochondral allograft (OCA) transplantation is an effective treatment for defects in the medial femoral condyle (MFC), but the procedure is limited by a shortage of grafts. Lateral femoral condyles (LFCs) differ in geometry from MFCs but may be a suitable graft source. The difference between articular surface locations of the knee can be evaluated with micro–computed tomography imaging and 3-dimensional image analysis.
Read moreReconstruction with fresh distal tibial allograft (DTA) is an alternative option, with the theoretical advantages of restoring the glenoid articular surface, improving joint congruity, and providing the biological restoration of articular cartilage loss.
Read moreThe biomechanical properties of allografts sterilized at a dose range of 17.1 to 21.0 kGy were not different from those of aseptic allografts.
Read moreBecause chondrocyte viability is imperative for successful osteochondral allograft transplantation, sterilization techniques must provide antimicrobial effects with minimal cartilage toxicity.
