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

MAT has shown to be an effective surgical treatment with good survivorship and functional outcomes at medium to long term follow-up. Patients with lower grades of cartilage damage have better MAT survivorship but all patients benefit clinically.

To compare clinical outcomes between a distal tibia allograft (DTA) reconstruction or a Latarjet procedure for patients with recurrent shoulder instability.
Read moreThe 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.
Read moreThere is good evidence for use of new techniques including the distal tibia allograft, which can be used as reconstruction options.

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.
Read moreOsteochondral allografts are used to fill deeper bone defects where the thin osseous layer of cryopreserved OCA implants are not sufficient for these deeper lesions.
Read moreThe 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.
Read moreThere was not a significant difference in clinical outcomes between the two groups suggesting that condyle-specific matching may not be necessary.
Read moreOverall, there seems to be no significant difference between the postoperative patient reported outcomes in terms of isolated MAT and combined MAT.
Read moreTo assess meniscal allograft transplantation (MAT) outcomes and compare the results of different root fixation techniques through systematic literature review. The significant overall improvements in function and pain scores accompanied by low allograft failure rates suggest that MAT is a reliable option. The current data does not demonstrate a difference in fixation method which may suggest that it does not have a significant influence on clinical outcome.

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.
Read moreOCA 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.

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.

Patients undergoing lateral meniscal allograft transplantation demonstrated greater pain relief and functional improvement than patients undergoing medial meniscal allograft transplantations.
Read moreAt 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.
Read moreFresh distal tibia allograft reconstruction results in a clinically stable joint with excellent outcomes in reducing the rate of dislocation and improving pain and function.
Read moreThis 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.
Read moreThis paper explores the technique for anatomical glenoid reconstruction using a fresh osteochondral distal tibia allograft after a failed Latarjet procedure.
