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.

Failure of Meniscus Allograft Transplantation

In select patients with an initial functional improvement following MAT prior to subsequent failure, RMAT may be indicated to alleviate pain and perhaps delay progression of osteoarthritis.

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.

Arthroscopic Microfracture for Osteochondral Lesions of the Talus

Second-look arthroscopic results revealed that 36% of lesions were incompletely healed and had inferior quality of repair tissue compared with that of native cartilage at a mean of 3.6 years, although arthroscopic microfracture provided functional improvements.
