1-stage total knee arthroplasty and proximal tibial non-union correction using 3-D planning and custom-made cutting guide

Primary total knee arthroplasty (TKA) in the presence of extra-articular deformity and non-union is challenging (Papagelopoulos et al. 2007, Sculco et al. 2019). Bony correction can be staged prior to TKA surgery or simultaneously as a 1-stage procedure. 1-stage procedures are well described in cases with tibial deformity (Wang and Wang 2002, Xiao-Gang et al. 2012, Catonné et al. 2019) and have also been described for proximal tibial non-union (Moskal and Mann 2001, Papagelopoulos et al. 2007).

We present a new technique in which 3-dimensional (3D) planning and a custom-made cutting guide were used in a 1-stage procedure treating a complex case with posttraumatic knee osteoarthritis, proximal non-union, and deformity.
