Demographics and Distal Tibial Dimensions of Suitable Distal Tibial Allografts for Glenoid Reconstruction

To evaluate whether characteristics such as age, height, weight, sex, or body mass index affected the distal tibial dimensions and radius of curvature (ROC) of a potential donor for anterior glenoid augmentation.

ConclusionBimeniscal replacement by an allograft and/or substitute provides good short-term functional and anatomical outcomes. Nevertheless, this procedure is warranted only in highly selected patients.Level of evidenceIV, retrospective study.

Coady, Ivan WongAbstractRecurrent instability after anterior shoulder stabilization surgery is not an uncommon complication, with variable rates of recurrences associated with different surgical procedures. The Latarjet procedure continues to be the gold standard in the management of anterior instability with significant glenoid bone loss, although a recent trend toward arthroscopic anatomic glenoid reconstruction (AAGR) with distal tibial allograft has been noted, with excellent short-term results and minim...

Chakrabarti, Patrick J. McGahan, James L. ChenAbstractAnterior cruciate ligament (ACL) tears are unfortunate but common injuries in the athletic population. The standard of care for ACL tears is a surgical intervention to reconstruct the ACL to restore knee functionality as well as quality of life. In recent years, bone marrow aspirate concentrate (BMAC) has seen increasing use in various orthopaedic settings. This increase can be attribu...

KenneyAbstractRecurrent shoulder instability complicated by capsular insufficiency due to underlying soft-tissue disorders or multiple prior failed surgical procedures poses a challenging surgical problem. Traditional capsulolabral soft-tissue reconstruction techniques are less effective in this setting, and bony procedures sacrifice normal anatomic relations. The described arthroscopic technique aims to prevent instability while maintaining range of motion through creation of a soft-...

What happens to acellular human dermal allograft (AHDA) after shoulder superior capsular reconstruction? AHDA appears to be a biological scaffold supportive of cellular infiltration, neovascularization, and incorporation of connective tissue. The process may be associated with inferior biomechanical properties during graft remodeling.

The purpose of this study was to evaluate biomechanical and histopathological results of a retrieved acellular human dermal allograft (AHDA) after superior capsule reconstruction (SCR). A 67-year-old man with pseudoparalysis was treated with SCR for an irreparable posterosuperior rotator cuff tear. The patient failed clinically 4.5  months postoperatively and elected to undergo reverse total shoulder arthroplasty (RTSA). At the time of RTSA, the AHDA was harvested. Biomechanical and histopathologic analyses were performed and compared to native grafts.

Acellular human dermal allograft commonly is used in the surgical treatment of complex rotator cuff tears, but little information is known about the biological fate of these grafts in human subjects. In this case report, the authors describe a patient who presented with a radiographically healed acellular human dermal allograft superior capsular reconstruction but had humeral head avascular necrosis. The healed superior capsular reconstruction, including graft −bone interfaces, was explanted after 7 months and sent for histologic analysis.

Meniscal allograft transplantation has been reported to be an excellent treatment for young patients with symptoms related to meniscal deficiency. To date, several studies reporting on extrusion or shrinkage after a meniscal transplant have failed to correlate these findings with clinical outcomes. However, longevity, graft durability, and overall joint health have yet to be determined in the context of graft extrusion and shrinkage. Given a growing body of evidence showing varying degrees of shrinkage over time with no effect on functional outcome, allograft morphologic changes may not be as clinically important as once t...

To evaluate the incidence and degree of shrinkage of transplanted fresh-frozen meniscal allografts in a long-term period of>8  years and to investigate whether the shrinkage of allograft progresses and is associated with inferior clinical and radiologic outcomes after meniscal allograft transplantation (MAT) in the long term.
