Comparative Study of Design and PCL-Substituting Systems of Total Knee Prosthesis

Abstract

Knee arthroplasty represents a laborious surgical procedure, involving a high degree of difficulty, concerning the bony tissue as well as soft tissues. Nevertheless, knee arthroplasty represents a procedure frequently used in orthopaedic clinics around the world, and its incidence it keeps growing [1].

Can prosthesis design of total knee arthroplasty affect balance?

“…Adam et al [6] compared various PCL-substitution implants in terms of the American Knee Society scores over 24 months. Kim et al [19] presented 68 monthfollow-up data.…”

“…[5] It is well-established that posterior cruciate ligament (PCL)-retaining and PCL-substitution prostheses are placed during total knee arthroplasty (TKA) in elderly with advanced gonarthrosis. [6] However, it remains unclear whether the implant design affects the balance and fall risks. One of the most controversial issues in TKA is whether to substitute or retain the PCL and it has been suggested that the choice is associated with risks of poor balance and falls postoperatively.…”
