“…(36,37) The latter has been shown to correlate well with patient satisfaction. (38) Although the use of these scales may indicate improvement in the majority of patients, (14,35) there remains a significant proportion of patients who are dissatisfied with the outcome of the TKA.

“…Many recent studies have sought to predict patient outcomes based on various preoperative patient characteristics, including radiographic findings, knee function scores, mental health, and socioeconomic status. 14,[17][18][19][20][21][22][23][24] Each of these variables has shown to have some predictive value but each has significant limitations. The situation is further complicated by the relatively weak association between symptoms of patients with OA and radiographic findings.…”

Introduction: Total knee arthroplasty (TKA) is the preferred surgical treatment for end-stage osteoarthritis. However, substantial numbers of patients still experience poor outcomes. Consequently, it is important to identify which patient characteristics are predictive of outcomes in order to guide clinical decisions. Our hypothesis is that preoperative patient-reported outcome measures and radiographic measures may help to predict TKA outcomes. Methods: Using cohort data from the Osteoarthritis Initiative, we studied 172 patients who underwent TKA. For each patient, we compiled pre-and postoperative Western Ontario and McMaster University Arthritis Index (WOMAC) scores. Radiographs were measured for knee joint angles, femorotibial angles, anatomical lateral distal femoral angles, and anatomical medial proximal tibial angles; Kellgren and Lawrence (KL) grades were assigned to each compartment of the knee. All studied measurements were compared to WOMAC outcomes. Results: Preoperative WOMAC disability, pain, and total scores were positively associated with postoperative WOMAC total scores (P ¼ .010, P ¼ .010, and P ¼ .009, respectively) and were associated with improvement in WOMAC total scores (P < .001, P < .001, and P < .001, respectively). For radiographic measurements, preoperative joint angles were positively associated with improvements in postoperative WOMAC total scores (P ¼ .044). Combined KL grades (medial and lateral compartments) were negatively correlated with postoperative WOMAC disability and pain scores (P ¼ .045 and P ¼ .044) and were positively correlated with improvements in WOMAC total scores (P ¼ .001). Conclusions: All preoperative WOMAC scores demonstrated positive associations with postoperative WOMAC scores, while among the preoperative radiographic measurements only combined KL grades and joint angles showed any correlation with postoperative WOMAC scores. Higher preoperative KL grades and joint angles were associated with better (lower) postoperative WOMAC scores, demonstrating an inverse correlation.

“…1,14 Although other modes of treatment such as conservative and surgical treatment exists the definitive therapy is joint replacement, and TKA has been shown to be an effective treatment option. 2 Hence many different scores and methods were developed to assess the outcome of this procedure, including the surgeons questioning the patient about his illness and treatment 8 and objective scales such as WOMAC,KSS, SF-36 etc which have shown some degree of correlation with patient satisfaction 17 , but still some patients are dissatisfied, some studies report a dissatisfaction rate of 19% 7,8,9,16 And it is also known that there is a dissonance between the surgeon reported outcomes and patient reported outcomes. In a study by Yuan et al, it is reported that the outcome of 60 patients satisfaction to be 91% [9] while Nunez et al in a study of 112 patients report satisfaction rate to be 86% 16 Which are similar to our study results of 91.74%.…”

ABSTRACT… Objectives: We aim to evaluate the level of satisfaction after total knee arthroplasty procedure in the patient population at a tertiary care hospital in Karachi, Pakistan, and to assess the relationship between patient satisfaction and the outcome based on traditional scores. Methods: Study Design: Case series for determination of patient satisfaction. Period: One year duration from April 2015 to May 2016. Setting: Tertiary care centre in Karachi, Pakistan. The inclusion criteria was all the patients with late stage osteoarthritis of the knee joint and underwent total knee arthroplasty at our institute. Data was analyzed using SPSS version 22. Results: A total of n= 102 patients were included in the study while n= 109 knee surgeries were done in total (n= 95 patients had unilateral surgery, while n= 7 patients had bilateral surgeries on both the knee joints) n= 58 patients were females while n= 44 patients were males, the median age was 60 years, patients had a mean body mass index (BMI) of 27kg/ m 2 . Of the total surgeries performed n= 100 were in the satisfaction group while n= 9 were in the dissatisfaction group. The majority of the patients reported that they would recommend the procedure. The co morbid conditions did not affect the patient's level of satisfaction having a p value of 0.678. In the dissatisfied group, there was no significant difference when it comes to gender, the mean age of patients in the dissatisfaction group was higher than the mean age of patients in the satisfaction. We found that WOMAC scores for functioning and the final WOMAC scores were correlated with patient satisfaction and that was statistically significant, similarly SF-36 form patients were satisfied about the improvement in the physical health while they did not improve the mental health aspect of their disease. Conclusion: According to our study total knee arthroplasty is an effective treatment for osteoarthritis of the knee, patient satisfaction is correlated with post-operative WOMAC function and overall scores, and SF-36 physical component. It is important to keep patients expectations in check through proper counseling. Key words:Osteoarthritis; patient satisfaction; total knee arthroplasty; TKA.

Expectation, satisfaction and clinical outcome of patients after total knee arthroplasty

Abstract: This study has shown that patient satisfaction correlates well with the clinical outcome according to the KSS, WOMAC and SF-36. The indication for TKA should consider the general health, emotional role and knee function of the patients as well in order to predict patient's outcome.
