TKA outcomes after prior bone and soft tissue knee surgery

Abstract

This study confirms that prior knee surgery could be considered a clinical condition predisposed to higher postoperative complication rate in primary TKA compared to the no prior surgery group. After analysing the three study groups, group C showed a higher rate of postoperative local complications and lower IKS knee scores, while the group B showed the poorest postoperative mean values of knee flexion as well as the need for extended surgical approach (TTO approach) was more prevalent in this study group. However, statistical analysis did not reveal a direct correlation between the type of prior knee surgery and TKA failures.

Clinical Outcome of Total Knee Arthroplasty After Prior Microfracture: A Matched Cohort Study

“…Primary TKA is a reliable procedure for the improvement of pain and function. 17,18 A retrospective study compared the results of TKA in patients with prior bony or soft tissue surgical procedures with primary TKA without prior proce- 19 The IKS knee score improvements were lower in the groups with prior procedures, with the soft tissue procedure group showing the smallest IKS change. A study of patients with a history of 2 or more arthroscopic procedures before TKA did not show a difference in KSS score improvement compared with primary TKA without prior procedures.…”

“…33 In a study of prior soft tissue procedures with 10 years of follow-up, a significantly higher number of postoperative complications and an insignificantly lower survivorship rate (94.8% vs 98.1% in the control group, respectively) were identified. 19 A study of 35 knees with osteochondral allograft transplantation before TKA demonstrated a 17% revision rate due to aseptic loosening. 34 In the current series, 1 (5%) patient with prior MFX developed polyethylene wear requiring tibial liner exchange at 5 years.…”

Gait knee kinematic alterations in medial osteoarthritis: three dimensional assessment

“…They had been scheduled for total knee arthroplasty (TKA). Diagnosis was based on clinical history, physical examination and radiographic evaluation that included comparative anteroposterior knee view with monopodal support, bilateral posteroanterior view at 45°flexion in weight-bearing, comparative lateral view at 30°flexion, axial view at 30°flexion and stress valgus and varus X-ray using a Telos system [15]. Malalignment was confirmed by measuring mechanical axis of the leg, hip-knee-ankle (HKA) angle, from bilateral weightbearing anteroposterior long-leg films.…”

Continuous passive motion and its effects on knee flexion after total knee arthroplasty in patients with knee osteoarthritis

“…Knee flexion range is a useful measure and accurate indicator of TKA outcomes. Previous clinical studies have reported mean final knee flexions ranging from 100° to 130°, regardless of the surgical technique or prosthetic design [32,40,42].…”
