Abstract

Preoperative planning is a fundamental element in total knee arthroplasty (TKA). A previous surgery that must be recognized and identified preoperatively is the Hauser procedure, a posteromedialization of the tibial tubercle for recurrent patellar instability. Here, we describe 2 case reports in patients with previous Hauser surgeries. The first TKA surgery was complicated from a standard medial peripatellar approach resulting in complete transection of the patellar tendon during standard arthrotomy. The tendon was repaired, and the arthroplasty was aborted. For the second case, correct preoperative identification of the Hauser procedure was performed. The second TKA surgery was performed using a lateral peripatellar arthrotomy with excellent exposure, resulting in a successful operation. Here, we highlight the importance of an accurate history, physical and radiographic examination, and the recommendation of an alternative TKA approach to help avoid the serious intraoperative complication of a patellar tendon laceration.
