AbstractIntroduction: The posterior cruciate ligament (PCL) in total knee arthroplasty (TKA), so-called cruciate-retaining (CR), or to substitute for it, so-called posterior stabilized (PS), continues to engage orthopaedists. The many reasons for retaining the posterior cruciate ligament (PCL) during total knee replacement (TKR) include improved stability, reduced shear stresses at the fixation interface, improved proprioception, and more efficient gait patterns during level walking and stair climbing;
Material and Method: This is prospective study design was at Gadag Institute of Medical Sciences ,Gadag, Karnataka. The study period was from October 2021 to March 2022.
Results: There were many prospective studies with the evidence level 1–2 to compare the CR and PS TKAs using contemporary prostheses. Most studies reported no difference in clinical scores, ROM, midterm survival rate, and quadriceps muscle recovery; two studies reported only the better ROM in PS TKAs. In our preliminary prospective study using the recently introduced prosthesis of Persona, all the clinical results did not differ at 1 year postoperatively.
Conclusion: CT TKA may not be feasible in certain conditions; PCL insufficiency, severe deformity, and the history of previous traumas or operations should be carefully examined for appropriate selection of the prosthesis type. The surgeon should have a clear idea on the technical differences between CR and PS TKAs. The extent of distal femoral resection, selection of femoral component size, and adjustment of tibial slope are particularly crucial for successful TKA.
