Osteoarticular Allograft Transplantation of the Trochlear Groove for Trochlear Dysplasia

Osteoarticular Allograft Transplantation of the Trochlear Groove for Trochlear Dysplasia

Dr. LaPrade recently published a case report for transplanting a very large trochlear allograft in a 21 year old female patient with trochlea dysplasia.

Lesion Size Does Not Predict Outcomes in Fresh Osteochondral Allograft Transplantation

Many cartilage repair algorithms use lesion size to choose the appropriate surgical technique. The purpose of this study was to determine if lesion size affects outcomes after an osteochondral allograft (OCA) transplantation. The results of this study suggest that graft size does not influence outcomes or survivorship. OCA transplantation is an effective treatment in the femoral condyle regardless of size.

Outcomes of Latarjet Versus Distal Tibia Allograft for Anterior Shoulder Instability Repair

Outcomes of Latarjet Versus Distal Tibia Allograft for Anterior Shoulder Instability Repair

To compare clinical outcomes between a distal tibia allograft (DTA) reconstruction or a Latarjet procedure for patients with recurrent shoulder instability.

Fresh Femoral Head Osteochondral Allograft Transplantation for Treating Osteochondritis Dissecans of the Femoral Head

The use of fresh-stored osteochondral allograft allows surgeons to both avoid donor-site morbidity and treat lesions of a larger surface area as a treatment options for the management of osteochondritis dissecans.

Management of Glenoid Bone Loss with Anterior Shoulder Instability

There is good evidence for use of new techniques including the distal tibia allograft, which can be used as reconstruction options.

Graft Transfer Technique in Arthroscopic Posterior Glenoid Reconstruction with Distal Tibia Allograft

Graft Transfer Technique in Arthroscopic Posterior Glenoid Reconstruction with Distal Tibia Allograft

Posterior glenoid augmentation is a technically demanding procedure that requires strict surgical indication. Although both iliac crest and distal tibia allograft have been shown to restore glenohumeral contact pressures, the authors prefer distal tibia allograft because of its congruity to the articular surface, lack of graft harvest morbidity, and retained cartilaginous surface for articulation with the native humeral head in a patient cohort that is at risk for progressive osteoarthritic development.

Viable Osteochondral Allograft for the Treatment of a Full Thickness Cartilage Defect of the Patella

Osteochondral allografts are used to fill deeper bone defects where the thin osseous layer of cryopreserved OCA implants are not sufficient for these deeper lesions.

Osteochondral Allograft Transplants for Large Trochlear Defects

The advantages of using the described OCA technique is that it allows chondral defects to be immediately filled with mature articular cartilage, it avoids the donor-site morbidity, and histologic analysis of OCA has shown high survivorship of the transplanted hyaline cartilage.

Condyle-Specific Matching Does Not Improve Midterm Clinical Outcomes of OCA Transplantation

There was not a significant difference in clinical outcomes between the two groups suggesting that condyle-specific matching may not be necessary.

Concomitant Reverse Hill-Sachs Lesion and Posterior Humeral Avulsion of the Glenohumeral Ligament

Concomitant Reverse Hill-Sachs Lesion and Posterior Humeral Avulsion of the Glenohumeral Ligament

Given the loss of integrity in the subchondral bone that occurs with other techniques as well as the persistent damage to the articular cartilage, many have begun to favor anatomic reconstruction with osteochondral allograft.

Fresh Osteochondral Allograft Transplantation for Focal Chondral Defect of Humerus Associated with Failed SLAP Repair

OCA transplantation of the humeral head has previously been described for the treatment of Hills-Sachs lesions associated with glenohumeral instability. Promising results have also been reported using this technique for humeral head articular cartilage defects.

Tibial Allograft Transfer for Medial Tibial Plateau Resurfacing

Tibial Allograft Transfer for Medial Tibial Plateau Resurfacing

This paper discusses the preparation and the implantation of the medial tibial plateau and medial meniscal allograft. The most important finding of this report is that tibial allograft transplant offers a viable solution in patients with large osteochondral defects in the setting of ligament injuries.

Distal Tibia Allograft Glenoid Reconstruction in Recurrent Anterior Shoulder Instability

At an average follow-up of 45 months, fresh DTA reconstruction for recurrent anterior shoulder instability results in a clinically stable joint with excellent clinical outcomes and minimal graft resorption. Optimal allograft placement resulted in superior bony incorporation with the native glenoid.

Distal Tibia Allograft Glenoid Reconstruction in Recurrent Anterior Shoulder Instability

Fresh distal tibia allograft reconstruction results in a clinically stable joint with excellent outcomes in reducing the rate of dislocation and improving pain and function.

Return to Sport and Recreational Activity After Osteochondral Allograft Transplantation in the Knee

This paper assesses osteochondral allograft (OCA) survivorship in an athletic patient population as well as determine the level of sport patients are able to return to post-operatively. OCA transplantation can be a successful solution for cartilage injuries in athletes as it allows the majority of patients to resume their highly active lifestyles.

Anatomical Glenoid Reconstruction Using Fresh Osteochondral Distal Tibia Allograft After Failed Latarjet Procedure

This paper explores the technique for anatomical glenoid reconstruction using a fresh osteochondral distal tibia allograft after a failed Latarjet procedure.

Osteochondral Allograft Transfer for Treatment of Osteochondral Lesions of the Talus

Despite the high incidence of reoperation and failure, carefully selected patients can experience substantially improved function as a result of fresh OCA transplantation in the talus.

Fresh Osteochondral Allograft Transplantation for Fractures of the Knee

The purpose of this paper is to determine functional outcomes and osteochondral allograft (OCA) survivorship in patients that received an OCA transplantation as a salvage treatment for knee fracture. Although the reoperation rate is high, treating osteochondral lesions associated with knee fractures with an OCA can be a successful salvage treatment option.
