Posterior shoulder dislocations are accompanied by high forces and can result in an anteromedial humeral head impression fracture called a reverse Hill-Sachs lesion. This reverse Hill-Sachs lesion can result in serious complications including posttraumatic osteoarthritis, posterior dislocations, osteonecrosis, persistent joint stiffness, and loss of shoulder function. Treatment is challenging and depends on the amount of bone loss. Several techniques have been reported to describe the surgical treatment of lesions larger than 20%...

BACKGROUND: Osteochondritis dissecans (OCD) is a disorder of subchondral bone that causes adverse effects on the overlying cartilage and commonly affects the knee. The incidence of OCD and its long-term effect on the knee joint are controversial. Hypothesis/Purpose: The purpose of this study was to (1) evaluate the rate of osteoarthritis and knee arthroplasty in a population-based cohort of patients with OCD lesions treated operatively and (2) evaluate factors that may predispose patients to knee osteoarthritis and arthroplasty...

The treatment of recurrent glenohumeral instability, especially with a concomitant bony lesion, remains challenging. This is especially true in the case of posterior instability given its less common incidence. Moreover, the presence of an engaging reverse Hill-Sachs lesion in combination with posterior instability will result in the need for a more aggressive treatment option. In comparison with a Hill-Sachs lesion, a reverse Hill-Sachs lesion features greater chondral deficiency that must be addressed during treatment...

Symptomatic osteochondral lesions of the patellofemoral joint are clinically challenging to manage because of the limited healing potential of articular cartilage; the complex morphology of the patellofemoral joint; the heterogeneity of the articular surface between patients; and high stresses across the joint, which can be altered by malalignment, tilt, or maltracking. Indications for surgery include traumatic lesions, osteochondritis dissecans, and high-grade chondromalacia in association with persistent pain despite a course of nonsurgical management...

Osteochondral lesions of the talus (OLTs) are an increasingly implicated cause of ankle pain and instability. Several treatment methods exist with varying clinical outcomes. Due in part to successful osteochondral allografting (OCA) in other joints, such as the knee and shoulder, OCA has gained popularity as a treatment option, especially in the setting of large lesions. The clinical outcomes of talar OCA have been inconsistent relative to the positive results observed in other joints. Current literature regarding OCA failure focuses mainly on 3 factors: the effect of graft storage conditions on chondrocyte viability, graft/lesion size, and operative technique...

Umbilical cord Wharton's jelly-derived mesenchymal stem cell (WJMSC) is a new-found mesenchymal stem cell in recent years with multiple lineage potential. Due to its abundant resources, no damage procurement, and lower immunogenicity than other adult MSCs, WJMSC promises to be a good xenogenous cell candidate for tissue engineering. This in vivo pilot study explored the use of human umbilical cord Wharton's jelly mesenchymal stem cells (hWJMSCs) containing a tissue engineering construct xenotransplant in rabbits to repair full-thickness cartilage defects in the femoral patellar groove...

Successful management of patellar osteochondral lesions has proved difficult, with unreliable outcomes reported using traditional cartilage repair and restoration procedures. Unique considerations for this type of defect include the multiplanar contours of the articular surface of the patella, high compressive and shear forces with knee range of motion that may disrupt graft healing, and the potential need for concomitant surgery to address patellar malalignment and instability. We describe our preferred method for treatment of a symptomatic chondral defect in the setting of recurrent patellar instability using particulated juvenile articular cartilage allograft transplantation and medial patellofemoral ligament reconstruction with semitendinosus allograft...

An important consideration for the successful use of fresh osteochondral allografts for the patellofemoral joint is selection of appropriately sized donor allografts. This is particularly challenging for matching grafts to the patella because of the substantial variability in articular contour that exists. At present, selection of donor patellae is based only on the width of the proximal tibia, with no established means of quantifying basic patellar size, facet configuration, or articular contour. We hypothesized that using a combination of standard radiographic measurements to generate an accurate profile of the recipients native patella would result in a more accurate donor graft...

EDITORIAL
C Niek van Dijk
In general, osteochondral allograft should include minimal "osteo" or bone. In cases that require a bulk allograft, even after creeping substitution and healing, most of the graft remains dead bone. Bulk dead bone is a particular problem in the talus, should a patient need revision to a prosthesis or arthrodesis. As an alternative, drilling, bone grafting, and fixation of existing cartilage, when possible, is preferred.
