Osteochondral 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.

The 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.
Read moreOsteochondral distal metatarsal allograft reconstruction is a safe and effective procedure for treatment of painful, degenerative conditions of the metatarsophalangeal joints.
Read moreRecent data suggest that anterior cruciate ligament (ACL) reconstruction with irradiated allograft tissue may lead to increased failure rates.
Read moreTibiotalar arthritis in the young, active patient is a debilitating condition with limited treatment options where bipolar tibiotalar fresh osteochondral allograft transplantation was conceived as a possible option.

For defects with a large diameter, large cystic component, or heavily involving the shoulder of the talus, an allograft provides an excellent option.
Read moreThe purpose is whether a metatarsal allograft can be used for a giant bone tumor.
Read moreThe transplantation of fresh osteochondral allograft is a viable and effective method for the treatment of osteochondral lesions of the talus as evidenced by improvements in pain and function.
Read moreThe data in this paper suggest that irradiation can be used to sterilize BPTB allograft without adversely affecting clinical outcome.
