A catastrophic complication during primary total knee arthroplasty: acute rupture of patellar tendon. A case report with literature review
CaseRepClinPractRev 2007; 8:250-254
Background: Intraoperative patellar tendon rupture is an uncommon and catastrophic complication. No detailed information exists on patellar tendon ruptures occurring intraoperatively during primary total knee prosthesis.
Case Report: We report 70-years-old patient with patellar tendon rupture during a total knee arthroplasty is presented. Also, simple, cheap and easy augmentation of the patellar tendon using a cerclage wire enabling an immediate mobilization is described.
Conclusions: The surgeon should avoid extreme forcing requiring for patellar eversion in stiff knees. However, patellar tendon rupture occurring intraoperatively despite all attempts to prevent it may be repaired readily, successfully and in a cheap way with a simple cerclage wire applied
among primary repair without requiring any immobilization and all other techniques as well as without additional surgical experience or any complicated material.
