title: The "banana peel" exposure method in revision total knee arthroplasty.
abstract: We present an exposure technique, the "banana peel," that has been used exclusively for revision total knee arthroplasty (TKA) for more than 20 years. We retrospectively reviewed use of this technique in 102 consecutive patients (mean age, 62 years; range, 41-92 years) who underwent tibial-femoral stemmed revision TKA. There were 5 deaths, leaving 97 patients (98 knees) for the study. The technique involves peeling the patella tendon as a sleeve off the tibia, leaving the extensor mechanism intact with a lateral hinge of soft tissue. A quadriceps "snip" is also done proximally. Patients with a minimum follow-up of 24 months were included. Telephone interviews and chart reviews were conducted, and Knee Society scores were obtained. Mean follow-up was 39 months (range, 24-56 months). No patient reported disruption of the extensor mechanism or decreased ability to extend the operative knee. Mean Knee Society score was 176 (range, 95-200). Mean postoperative motion was 106 degrees. No patient reported pain over the tibial tubercle. The banana-peel technique for exposing the knee during revision TKA is a safe method that can be used along with a proximal quadriceps snip and does not violate the extensor mechanism, maintaining continuity of the knee extensors.
