The Use of Structural Allograft in Primary and Revision Knee Arthroplasty with Bone Loss

الملخص EN

Bone loss around the knee in the setting of total knee arthroplasty remains a difficult and challenging problem for orthopaedic surgeons.

There are a number of options for dealing with smaller and contained bone loss; however, massive segmental bone loss has fewer options.

Small, contained defects can be treated with cement, morselized autograft/allograft or metal augments.

Segmental bone loss cannot be dealt with through simple addition of cement, morselized autograft/allograft, or metal augments.

For younger or higher demand patients, the use of allograft is a good option as it provides a durable construct with high rates of union while restoring bone stock for future revisions.

Older patients, or those who are low demand, may be better candidates for a tumour prosthesis, which provides immediate ability to weight bear and mobilize.
