The use of fresh osteochondral allografts for the treatment of osteochondral defects of the knee is based on a scientific rationale and on long-term clinical experience.

The partial talus or “shell” technique is an alternative to the plug technique and may be useful for large or cystic lesions that require reconstruction of 20% or more of the talar dome ().In these cases, it may be technically difficult to secure multiple plugs or it may be easier to perform an anatomical reconstruction with a partial talus graft.

That makes now the perfect time to study up on how to choose between osteochondral graft codes , , and JRF's osteochondral allografts in particular, and also their meniscal allografts, are treated differently to the rest of the soft tissue. allografts and other allografts that are sourced. The reason for this is that the fresh allografts need to be taken from the donor and put into the recipient within days.
Similar to osteochondral autograft, allograft replaces the entire osteochondral unit. Scheduling a procedure with a fresh allograft requires patients to be “on-call” so that upon graft availability, the graft may be transplanted. Many certified tissue banks have the ability to obtain, screen, and match (based on radiographic size) by: 3. fresh osteochondral allografts After harvest and 24 hours of treatment in an antibiotic solution, fresh osteochondral allografts, sometimes referred to as fresh-refrigerated to differentiate from fresh-frozen grafts, are stored in either a lactated ringers solution or a . The surgeon may select any portion of the humeral head for use as a graft with this procedure. It may be helpful to use the area of the humeral head fresh osteochondral allograft that matches the. Osteochondral allografts are typically used for larger lesions. Autologous or allogeneic minced cartilage, decellularized osteochondral allograft plugs, and reduced osteochondral allograft discs are also being evaluated as a treatment of articular cartilage lesions.

The use of osteochondral allografts to remedy bipolar lesions and arthritis remains controversial [7•, 8•]. Our Fresh graft Osteochondral Graft Program is designed to offer a variety of allograft choices for joint reconstruction procedures to repair articular cartilage and subchondral bone defects.
These osteochondral bio-implants allow orthopedic surgeons to transplant mature hyaline cartilage with viable chondrocytes and subchondral bone into recipient's damaged articular.

The use of fresh osteochondral allografts to the patellofemoral joint has been reported with poorer results compared to the femoral condyle or tibial plateau.

Orthopedics Today. Introduction. Osteochondral lesions of the talus are being recognized as an increasingly common injury, and may occur in up to 50% of acute ankle sprains and fractures, particularly in association with sports injuries 1, are most commonly located postero-medially (57%) or anterolaterally (43%), while centrally located lesions are uncommon 3.

Osteochondral grafting is a method of treating cartilage injuries that expose underlying bone. Osteochondral grafts replace both the articular cartilage on the surface and the underlying bone.
The tissue can come from other parts of the patient’s body (called osteochondral auto graft) or from a tissue donor (osteochondral allo graft). McCulloch, P & Görtz, SOsteochondral allograft transplantation: The rationale and basic science.

The implantation of osteochondral allografts is usually performed through an open incision, under general or spinal anesthesia. An incision is made to expose the joint defect.
The size of the defect is then measured and a portion of the cartilage and underlying bone is removed. Brian Cole, MD, MBA, (Chicago, IL) provides an in-depth scientific review of osteochondral allograft transplantation procedures.
Osteochondral allografts have been used for many years with reported patient satisfaction rates over 90% (Bugbee W. et al. The Journal of Knee Surgery ).

One treatment available for focal lesions is osteochondral allografts (OCA) transplantation. OCAs are reported to be successful in >75% of cases when used for treatment of focal femoral condyle lesions.
Currently, tissue banks store OCAs at 4ºC, and implantation is recommended. An osteochondral allograft is a pdf of tissue taken from a diseased donor to replace damaged cartilage that lines the ends of bones in a joint.
A section of cartilage and bone is removed, shaped to precisely fit the defect and then transplanted to reconstruct the damage. Disease Overview.Soft tissue allografts are alternate tissues that are utilized to rebuild poor ligaments, torn menisci, spinal surgery, and osteochondral deficiency during knee surgical procedure, thus acting as the major growth driver for the soft tissue allograft market.Osteochondral allografts are particularly ebook for osteochondral lesions such as Osteochondritis Dissecans, focal osteonecrosis or periarticular trauma where bone deformity or deficiency occurs in association with chondral disease.
