The Prevalence And Predictive Factors For Constrained Condylar Tka

Background: The essential factors for a successful total knee arthroplasty (TKA) include achieving optimal alignment, ensuring proper balance, and correcting deformities. Certain cases including severe deformities, substantial bone defects, stiffness, and instability are exceedingly challenging to rectify only through soft tissue release and necessitate the use of restricted prostheses, even in initial total knee arthroplasty (TKA). Under these conditions, the restricted condylar knee (CCK) method is the optimal selection. Aim of the This study sought to determine the prevalence and predicted characteristics related to the necessity of limited insert utilization in primary total knee arthroplasty (TKA). Patients and method: Retrospective study for 286 patients from January 2020 to January 2023 enrolling all patients underwent total knee arthroplasty arthroplasty in hospital of surgical specialties in medical city and two private hospitals in Baghdad. All patients underwent total knee arthroplasties (TKA) conducted by the same surgical team. We conducted a retrospective analysis of the preoperative and intraoperative factors related to the utilization of restricted inserts. A total of 42 knees needed constrained condylar stemmed total knee arthroplasty were found. Study population: 286 patients (76 males and 210 female) age from 27 to 79 years old. The inclusion criteria required that all patients underwent complete knee arthroplasty. Patients with revision knee arthroplasty and valgus knees were excluded from the study. Data collection and analysis: factors related to preoperative and intraoperative steps. The evaluated patient's age, BMI, range of motion, Knee Society Score (KSS), sex, (KL grade), alignment determined through anteroposterior (AP) standing radiographs. Results: The restricted implant was utilized in 42 out of 286 knees (14.6%). Preoperative and intraoperative clinical variables linked to an elevated modified probability of limited insert utilization encompassed significant varus deformity. A surgeon operating the curvature was developed to ascertain the appropriate threshold value of 17.6° for the tibiofemoral angle, indicating the requirement for a restricted implant. Conclusion: The preoperative factors examined comprised the patient's age, body mass index, range of motion, Knee Society Score (KSS), sex, Kallgren and Lawrence grading, alignment assessed via anteroposterior (AP) standing radiographs, and the gravity of the anatomical varus angle as indicated by the tibiofemoral angle
