Utility of Allograft Talus as a Source for Grafting of Concurrent Humeral and Glenoid Defects

Utility of Allograft Talus as a Source for Grafting of Concurrent Humeral and Glenoid Defects

This publication compares morphologic data of the talus using magnetic resonance images with previously reported values of the humeral head and the glenoid as a potential graft source for both the humeral head as well as glenoid reconstruction in the setting of concomitant glenoid and humeral head defects.

Failures of Realignment Osteotomy

Failures of Realignment Osteotomy

Osteoarthritis (OA) of the knee is a disabling condition in young active patients. Although the etiology of knee OA is multifactorial, increased mechanical load as a result of limb malalignment has been clearly identified as a risk factor for the occurrence and progression of disease.

Osteochondral Grafts Failures

The preoperative plan for revision cases must always include an assessment of the mechanism of failure. It is usually determined by history and symptoms, physical examination, imaging (prior and post index procedure) and intraoperative findings during the index procedure (operation notes).

Return to Work Following High Tibial Osteotomy With Concomitant Osteochondral Allograft Transplantation

In patients with focal chondral deficiency and varus deformity, HTO þ OCA provides a high rate of RTW (96.2%) by 3.5 2.9 months postoperatively. However, patients with greater-intensity occupations may take longer to return to work than those with less physically demanding occupations.
