Tips for expediting your fresh osteochondral allograft, tendon and meniscus orders
Read more Download PDFA 36-year-old patient reported persistent right knee crepitation and pain two years after falling directly onto their knee. Prior conservative management and arthroscopic chondroplasty was undergone without any resolution. Imaging and arthroscopy demonstrated a full-thickness cartilage defect in the lateral trochlea.
Three months post-operation, the patient has regained full range of motion. The pain and crepitation that they had been experiencing has also been resolved.

His cartilage was noted to be soft at that time. After his index surgery, he continued to have pain and mechanical symptoms. A follow up MRI showed a full thickness chondral defect as well as subchondral sclerosis.

He reported discomfort and stiffness in the knee, which were exacerbated by stairs and walking downhill. He subsequently developed recurring effusions. The patient’s symptoms persisted despite extensive non-operative management.

Read moreTogether, 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.

Soft 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 PDFAfter adjusting for patient age, gender, and body mass index, they found that the BioCleanse® technique—which sterilizes tissue through oscillating positive and negative pressure in the presence of detergents and sterilants—and irradiation with more than 1.8 Mrad were associated with a higher risk of revision after 1 year, compared to the other graft processing methods.
Read moreMeniscal 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 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.

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 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.
