A tibial tubercle osteotomy can provide reliable and safe exposure during revision total knee arthroplasty with a high union rate, low complication rate, and predictable outcomes.

The initial challenge and possibly the most important step in revision total knee arthroplasty is obtaining adequate exposure for removal and reimplantation of the tibial and femoral components. A medial parapatellar arthrotomy with synovectomy and scar tissue excision allows mobilization of the extensor mechanism and adequate exposure in the majority of cases1. However, certain cases, in particular those with arthrofibrosis and patella baja, require a more extensive exposure to safely mobilize the extensor mechanism for visualization. This can be done proximally through soft-tissue release of the extensor mechanism, via either a quadriceps turndown or quadriceps snip, or distally through a tibial tubercle osteotomy2.
