[Total knee artroplasty: degree of post-operative functionality in adults].

Introduction: the two most used types of prosthesis are posterior cruciate ligament preserving (CR) and posterostabilized (PS). Proponents of CR TKA cited greater stability, greater range of motion, better proprioception, and greater kickback associated with the native posterior cruciate ligament.

Objective: to assess the degree of pain, return of mobility and functionality of the joint of patients who had TKA, between the years January 2018 and December 2022 at the Juárez Centro Medical Surgical Unit, using their records as a study unit.

Material And Methods: observational, descriptive, retrospective and cross-sectional study in patients post-operative with total knee arthroplasty for the treatment of osteoarthritis. The universe studied included 87 patients, of these 22 corresponded to the Juárez Medical Surgical Unit of the Center, post-operated with posterostabilized total knee prosthesis, they were analyzed under the scale proposed by the KSS.

Results: the degree of functionality was assessed by the KSS scale, 50% of the patients presented a good clinical assessment and physical examination at the end of rehabilitation, 23% of the patients presented an excellent clinical assessment and physical examination, 23% of the patients presented regular clinical evaluation and physical examination, 4% of patients presented poor clinical evaluation and physical examination.

Conclusions: good functional results (73%) were obtained in patients operated by posterostabilized total knee arthroplasty in our Juárez del Centro Medical Surgical Unit.
