Patellar Reconstruction During Total Knee Arthroplasty for Previous Patellectomy.

Patellectomy, an uncommon procedure in the current era, poses a challenge in total knee arthroplasty (TKA), creating anteroposterior instability, anterior knee pain, and loss of mechanical advantage. The TKA is even more complicated when the patellectomy is performed secondary to lower limb malalignment with patellofemoral pain and instability. Here, we describe a case of patellectomy and malalignment, and the surgical technique for patellar reconstruction with concomitant TKA to address this complex scenario.
