Ten to twenty percent of patients are dissatisfied with the clinical result after total knee arthroplasty (TKA). Aim of this study was to investigate the impact of personality traits on patient satisfaction and subjective outcome of TKA. We investigated 80 patients with 86 computer navigated TKAs (Emotion®, B Braun Aesculap) and asked for patient satisfaction. We divided patients into two groups (satisfied or dissatisfied). 12 personality traits were tested by an independent psychologist, using the Freiburg Personality Inventory (FPI-R). Postoperative examination included Knee Society Score (KSS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and the Visual Analogue Scale (VAS). Radiologic investigation was done in all patients. 84% of our patients were satisfied, while 16% were not satisfied with clinical outcome. The FPI-R showed statistically significant influence of four personality traits on patient satisfaction: life satisfaction (ρ = 0.006), performance orientation (ρ =0.015), somatic distress (ρ = 0.001), and emotional stability (ρ = 0.002). All clinical scores (VAS, WOMAC, and KSS) showed significant better results in the satisfied patient group. Radiological examination showed optimal alignment of all TKAs. There were no complications requiring revision surgery in both groups. The results of our study show that personality traits may influence patient satisfaction and clinical outcome after TKA. Thus, patients personality traits may be a useful predictive factor for postoperative satisfaction after TKA

Complications such as implant loosening, infection, periprosthetic fracture or instability may lead to revision arthroplasty procedures. There is limited literature comparing single-stage and two-stage revision shoulder arthroplasty. This study aims to compare clinical outcomes and cost benefit between single-stage and two-stage revision procedures. Thirty-one revision procedures (mean age 72+/-7, 15 males and 16 females) performed between 2016 and 2021 were included (27 revision RSA, 2 revision TSA, 2 failed ORIFs). Two-stage procedures were carried out 4-6 weeks apart. Single-stage procedures included debridement, implant removal and washout, followed by re-prep, re-drape and reconstruction with new instrumentations. Clinical parameters including length of stay, VAS, patient satisfaction was recorded preoperatively and at mean 12-months follow up. Cost benefit analysis were performed. Seven revisions were two-stage procedures and 24 were single-stage procedures. There were 5 infections in the two-stage group vs 14 in the single-stage group. We noted two cases of unstable RSA and 8 other causes for single-stage revision. Majority of the revisions were complex procedures requiring significant glenoid and/or humeral allografts and tendon transfers to compensate for soft tissue loss. No custom implants were used in our series. Hospital stay was reduced from 41+/-29 days for 2-stage procedures to 16+/-13 days for single-stage (p<0.05). VAS improved from 9+/-1 to 2+/-4 for two-stage procedures and from 5+/-3 to 1+/-2 for single-stages. The average total cost of hospital and patient was reduced by two-thirds. Patient satisfaction in the single-stage group was 43% which was comparable to the two-stage group. All infections were successfully treated with no recurrence of infection in our cohort of 31 patients. There was no instability postoperatively. 3 patients had postoperative neural symptoms which resolved within 6 months. Single-stage procedures for revision shoulder arthroplasty significantly decrease hospital stay, improve patients’ satisfaction, and reduced surgical costs

There are numerous patient satisfaction questionnaires by none specific for an Independent Medical Examination (IME). The aim of this study was to develop and evaluate a questionnaire suitable for an IME. The questionnaire (IMESQ) consisted of five process domains (“Interpersonal manner”, “Communication”, “Technical ability”, “Information exchange”, “Time allocation”) and an outcome domain (“Satisfaction”), each with a five-scale Likert response. An 11-point numerical satisfaction scale (NSS) and a 3-point scale question on the “willing to undergo another examination with the doctor if required” were alternative measures of validation. The questionnaire was tested against numerous independent variables. Statistical analysis included Spearman correlation ((r. S. ) between the items in the questionnaire and the total score with the NSS, and “willing to undergo another examination with the doctor if required” with point-biserial correlation (r. pb. ). Internal consistent reliability was tested using split-half correlation coefficient (r. SB. ) and Cronbach's alpha coefficient (α). The construct was subjected to Factor Analysis. The results from 53 respondents were analysed. There was moderate to strong inter-item correlation (r. s. range 0.57 to 0.83, median 0.67, p < 0.01) and good correlation with the NSS (r. s. = 0.79, p < 0.01) and dichotomous question (r. pb. = 0.45, p < 0.01). Five respondents were “neither satisfied or dissatisfied” (Item 6) and 12 recorded “maybe” to further examination. The split-half correlation was strong (r. SB. = 0.76, p < 0.01). There was good internal consistency reliability (α = 0.92). “Interpersonal manner” (ψ = 4.3) was the only item to have an eigenvalue greater than one, accounting to 72% of the variance across the scale. Eigenvector analysis confirmed the questionnaire was unidimentional. The IMESQ is a brief questionnaire to assess satisfaction with an IME. It is validated and has good internal consistency reliability. The five process domains can identify areas of suboptimal performance: useful for a 360° audit

In patients admitted to hospital with a hip fracture, urinary issues are common. Despite guidelines that recommend avoiding foley catheter usage when possible, it remains a common part of perioperative care. To date, there is no prospective data on the safety and satisfaction associated with catheter use in such cohort. The aim of this study was to evaluate the satisfaction of patients when using a foley catheter while they await surgery for their fractured hip and the safety associated with catheter use. In our prospectively collected database, 587 patients were admitted to our tertiary care center over a 1 year period. Most patients (328) were catheterized within the first 24h of admission, primarily inserted in ED. Of these patients, 119 patients (61 catheterized and 58 noncatheterized) completed a questionnaire about their perioperative management with foley catheter usage administered on day 1 of admission. This was used to determine satisfaction of catheter use (if catheterized) and pain levels (associated with catheterized or associated with transferring/voiding if not catheterized). Adverse effects related with catheter use included urinary tract infection (UTI) and post-operative urinary retention (POUR). Ninety-five percent of patients found the catheter to be convenient. Only 5% of patients reported any pain with catheter use. On the contrary, 47.5% of non-catheterized patients found it difficult to move to the bathroom and 30.4% found it difficult to urinate. Catheterized patients had significative less pain than uncatheterized patients (0.62/10 vs 2.45/10 respectively, p < 0 .001). The use of nerve block reduced pain levels amongst catheterized patients but was not associated with reduced pain levels or satisfaction amongst non-catheterized patients. The use of catheter was not associated with increased risk of UTI(17.5% in the catheterized vs 13.3% in the non-catheterized, p = 0.541) or POUR (6.8% in the catheterized vs 11.1% in the non-catheterized, p = 0.406). This study illustrates the benefits and safety associated with the use of urinary catheters in the pre-operative period amongst hip fractures. The use of catheters was associated with reduced pain and satisfaction without increasing post-operative UTI or POUR. These findings suggest that pre-operative catheter use is associated with less pain and more satisfaction for patients awaiting hip surgery and whom other measures, such as nerve blocks, are unlikely to reduce the discomfort associated with the mobility required to void. A prospective randomized control study could lead to a more evidence based approach for perioperative foley catheter usage in hip fracture patients

Total knee arthroplasty (TKA) is considered as one of the most successful and cost-effective medical interventions yet it is consistently reported that up to 20% of patients are dissatisfied with their outcomes. Patient satisfaction is correlated with the fulfillment of expectations and an important aspect of this involves good surgeon-patient communication, which itself is a contributor to TKA satisfaction. The purpose of this study was to develop and test a checklist intended to enhance the quality of surgeon-patient communication by optimizing the surgeon's role in helping patients set (or reset) and manage post-TKA expectations that are realistic, achievable, and most importantly, patient-specific. In this prospective mixed methods study, a communication checklist was developed from the analysis of interviews with patients who were between six weeks and six months post-TKA. Four orthopaedic surgeons then used the checklist to guide discussions with patients about post-operative expectations and outcomes during follow-up visits between six weeks and six months. A visual analogue scale was used to survey two groups of patients on five measures of satisfaction: the standard of care communication group and the intervention group who had received the checklist. The mean scores of the two groups were compared using independent t-tests. The duration of follow-up visits was also tracked to determine if the checklist took significantly more time in practice. Themes from the qualitative analysis of eight patient interviews incorporated into the checklist included pain management, medication, physiotherapy, and general concerns and questions. The quantitative study comprised 127 participants, 67 in the standard of care communication group and 60 in the checklist group. There were no significant group differences in gender, BMI, comorbidities, post-operative complications, marital or occupational status, however the standard of care group was older by six years (p < .001). The checklist group reported significantly greater satisfaction on four of the five measures of satisfaction: TKA satisfaction and expectations met (p = .017), care and concern shown by the surgeons (p = .011), surgeons' communication ability (p = .008), and satisfaction with time surgeons spent with patients during follow-up visits (p < .001). Satisfaction with the TKA for relieving pain and restoring function was not significant (p = .064). Although the checklist increased the average clinic visit time by only 1 minute, 51 seconds, it was significantly greater (p = .001). The impact of age and gender on satisfaction was explored using a two-way analysis of variance. No significant effects or interactions were observed. Checklists have been shown to decrease medical errors and improve overall standards of patient care but no published research to date has used a communication checklist to enhance orthopaedic surgeon-patient communication. The present findings indicate that this simple tool can significantly increase patient satisfaction. This has practical significance because patient satisfaction is a metric that is increasingly used as a key performance indicator for surgeons and health care institutions alike. Increased TKA satisfaction will benefit patients, surgeons, and the health care system overall

Overall, hip and knee total joint replacement (TJR) patients experience marked benefit, with reported satisfaction rates of greater than 80% with regard to pain relief and improved function. However, many patients experience ‘nuisance’ symptoms, an annoyance which may cause discomfort, which can negatively impact postoperative satisfaction. The purpose of this study was to evaluate the prevalence of nuisance symptoms among TJR patients and impact on overall patient satisfaction. A prospective survey study to assess type and prevalence of primary hip/knee TJR related nuisance symptoms, and impact on patient satisfaction at six-months to one-year post-TJR was conducted. The survey was administered over a one-year period at one academic arthroplasty centre. Survey questions tapped occurrence of commonly reported nuisance symptoms (e.g. localized pain, swelling, stability, incision appearance/numbness, stiffness, clicking/noise, ability to perform activities of daily living), and impact of the symptom on overall hip/knee satisfaction rated on a 10-point visual analogue scale (VAS), (0=no impact, 10=to a great extent). Overall VAS satisfaction with TJR was also assessed (0=not at all satisfied, 10=extremely satisfied). Survey responses were analysed using descriptive statistics. The sample comprised of 974 primary TJR patients, including 590 knees (61%) and 384 hips 39%) who underwent surgery over a one-year period. Among knees, the most commonly reported nuisance symptoms and associated impact to satisfaction per mean VAS scores included: difficulty kneeling (78.2%, mean VAS 4.3, ±3.3), limited ability to run or jump (71.6%, VAS 3.3, ±3.3), numbness around incision (46.3%, VAS 3.8, ±3.3), clicking/noise from the knee (44.2%, VAS 2.7, ±2.7) and stiffness (43.3%, 3.3, ±2.7) following knee arthroplasty. Overall, 88.1% of knee patients surveyed experienced at least one self-reported nuisance symptom at one-year postoperative. Mean overall VAS satisfaction with knee TJR was reported as 9/10 (±1.7). Among hip TJR patients, the most commonly reported nuisance symptoms and associated impact to satisfaction per VAS scores were: limited ability to run or jump (68.6%, VAS 3.4, ±3.4), muscular pain in the thigh (44.8%, VAS 3 ±2.7), limp when walking (37.6%, VAS 4.1, ±3.2), hip stiffness (31%, VAS 3.1, ±2.4), and new or worsening low back pain (24.3%, VAS 2.9, ±2.5). Overall, 93.7% of patients experienced at least one self-reported nuisance symptom at one-year postoperative. Mean overall VAS satisfaction following total hip arthroplasty at one year was reported as 8.9/10 (±1.7). Nuisance symptoms following primary total hip and knee arthroplasty are very common. Despite the high prevalence of such symptoms, impact of individual symptoms to overall TJR satisfaction is minimal and overall TJR patient satisfaction remains high. Careful preoperative counselling regarding the prevalence of such symptoms is prudent and will help establish realistic expectations following primary hip and knee TJR

Abstract. Abstract:. Background. The dissatisfaction rate in patients operated with TKR is generally quoted to be around 20% in various registries in patients operated by multiple surgeons. The data of satisfaction rates following a TKR performed by single high volume surgeons is lacking. Aim. To study the satisfaction rate and Net Promoter Score (NPS) of consecutively operated TKR patients by a single surgeon with a minimum 1 year follow up. Methods. 860 out of 883 patients who were operated between 1st April, 2018 and 31st March, 2019 were contacted by a telephonic call. They were asked 3 questions related to their experience about the operation. The patient satisfaction, NPS and reason for dissatisfaction were assessed. Results. The overall satisfaction rate of 95.93% and a net promoter score of +96.63 was observed. When the NPS was calculated as the worst case scenario, a score of +93.70 was observed. 6 patients were unsatisfied with causes directly related to the surgery. Conclusion. TKR can have as high satisfaction rates with very high NPS in experienced surgical hands using standard techniques. These results may form a benchmark against which newer technologies can be compared

Introduction. W. ide . A. wake . L. ocal . A. naesthetic . N. o . T. ourniquet (WALANT) is a well- established day case procedure for carpal tunnel release with several advantages and enhanced post-operative recovery. Use of Local anaesthesia with Adrenaline using a 27G needle allows a bloodless field and distraction techniques achieve patient comfort during the procedure. Objectives. This retrospective, observational cohort study assesses patient satisfaction and undertakes functional evaluation using the validated Boston Carpal Tunnel Questionnaire (BCTQ) following WALANT technique for carpal tunnel release (CTR). The BCTQ has a symptom severity scale based on 11 items and a functional status scale of 8 elements. Further we compare surgical outcomes between techniques of WALANT and traditional CTR. Patient and Methods. We included 30 consecutive patients, 15 in each arm who either underwent traditional CTR with the use of Tourniquet or with the WALANTtechnique. Data was collected from Electronic Patient Records and hand therapy assessments. A satisfaction questionnaire and Visual Analogue Score (VAS) was utilized to evaluate subjective outcomes. Functional outcomes was assessed by BCTQ scoring system and clinical review. Microsoft Excel was used for analysis. Results. 100% of patients in the WALANT group stated they were satisfied with the operation. Relief from night pain and sleep disturbance were the most improved symptoms. BCTQ and clinical assessment evaluation between both groups revealed comparable results with no significant difference. Conclusion. With advantages of no tourniquet related pain, increased patient satisfaction and functional outcomes on the BCTQ scores, WALANT technique has the potential to be the standard technique for CTR

Introduction. Circular frames for ankle fusion are usually reserved for complex clinical scenarios. Current literature is heterogenous and difficult to interpret. We aimed to study the indications and outcomes of this procedure in detail. Materials & Methods. A retrospective cohort study was performed based on a prospective database of frame surgeries performed in a tertiary institution. Inclusion criteria were patients undergoing complex ankle fusion with circular frames between 2005 and 2020, with a minimum 12-month follow up. Data were collected on patient demographics, surgical indications, comorbidities, surgical procedures, external fixator time (EFT), length of stay (LOS), radiological and clinical outcomes, and adverse events. Factors influencing radiological and clinical outcomes were analysed. Results. 47 patients were included, with a mean follow-up of three years. The mean age at time of surgery was 63.6 years. Patients had a median of two previous surgeries. The median LOS was 8.5 days, and median EFT was 237 days. Where simultaneous limb lengthening was performed, the average lengthening was 2.9cm, increasing the EFT by an average of 4 months. Primary and final union rates were 91.5% and 95.7% respectively. At last follow-up, ASAMI bone scores were excellent or good in 87.2%. ASAMI functional scores were good in 79.1%. Patient satisfaction was 83.7%. 97.7% of patients experienced adverse events, most commonly pin-site related, with major complications in 30.2% and re-operations in 60.5%. There were 3 amputations. Adverse events were associated with increased age, poor soft tissue condition, severe deformities, subtalar fusions, peripheral neuropathy, peripheral vascular disease, and prolonged EFT. Conclusions. Complex ankle fusion using circular frames can achieve good outcomes in complicated clinical scenarios, however patients can expect a prolonged time in the frame and high rates of adverse events. Multiple risk factors were identified for poorer outcomes, which should be considered in patient counselling and prognostication

Patient satisfaction is an important measure of patient-centered outcomes and physician performance. Given the continued growth of the population undergoing surgical intervention for osteoarthritis (OA), and the concomitant growth in the associated direct costs, understanding what factors drive satisfaction in this population is critical. A potentially important driver not previously considered is satisfaction with pre-surgical consultation. We investigated the influence of pre-surgical consultation satisfaction on overall satisfaction following surgery for OA. Study data are from 1263 patients who underwent surgery for hip (n=480), knee (n=597), and spine (n=186) OA at a large teaching hospital in Toronto, Canada. Before surgery, patient-reported satisfaction with information received and degree of input in decision-making during the pre-surgical consultation was assessed, along with expectations of surgery (regarding pain, activity limitation, expected time to full recovery and likelihood of complete success). Pre- and post-surgery (6 weeks, and 3, 6, and 12 months) patients reported their average pain level in the past week (0–10, 10 is worst). At each follow-up time-point, two pain variables were defined, pain improvement (minimal clinically important difference from baseline ≥2 points) and ‘acceptable’ pain (pain score ≤ 3). Patients also completed a question on satisfaction with the results of the surgery (very dissatisfied/dissatisfied/somewhat satisfied/very satisfied) at each follow-up time point. We used multilevel ordinal logistic regression to examine the influence of pre-surgery satisfaction with consultation on the trajectory of satisfaction over the year of recovery controlling for expectations of surgery, pain improvement, acceptable pain, socio-demographic factors (age, sex, and education), body mass index, comorbidity, and depressive symptoms (Hospital Anxiety and Depression Scale). Mean age of the sample was 65.5 years, and over half (54.3%) were women. Overall, 74% and 78.9% of patients were satisfied with the information received and with the decision-making in the pre-surgical consultation, respectively, no significant differences were found by surgical joint (p=0.22). Post-surgery, levels of satisfaction varied very little over time (6 weeks: 92.5% were satisfied and 66.4% were very satisfied, 1 year: 91.1% were satisfied and 65.6% were very satisfied). Results from a model including time, surgical joint, satisfaction with consultation and control factors indicated that being satisfied with the information received in the pre-surgical consultation was associated with higher odds of being more satisfied after surgery (OR: 1.2, 95% CI: 1–1.4). Additionally, spine and knee patients were more likely to be dissatisfied than hip patients (OR: 3.2, 95% CI: 2.1–4.9 and OR: 2.5, 95% CI: 1.8–3.4 for spine and knee patients respectively). Achieving pain improvement (OR: 1.7, 95% CI: 1.3–2.4) and acceptable pain (OR: 2.5, 95% CI: 1.6–3.9) were both significantly associated with greater satisfaction. Pre-operative expectations were not significantly associated with post-surgery satisfaction. Findings highlight the important role of pre-surgery physician-patient communication and information on post-surgery satisfaction. This points to the need to ensure organizational provisions that foster supportive and interactive relationships between surgeons and their patients to improve patients' satisfaction. Findings also highlight that early post-recovery period (i.e. <= 3 months) as a key driver of longer-term satisfaction

Up to 20 percent of patients remain dissatisfied after primary total knee arthroplasty (TKA) surgery. Understanding the reasons for dissatisfaction post TKA may allow for better patient selection and optimized treatment for those who remain dissatisfied. The association between function, mobility and satisfaction are not well understood. The purpose of this study was to investigate the association between post-TKA satisfaction and i) pre-operative, ii) post-operative, and iii) change in knee joint function during gait. Thirty-one patients scheduled to receive primary TKA for knee osteoarthritis (OA) diagnosis were recruited and visited the Dynamics of Human Motion laboratory for instrumented walking gait analysis (using a synchronized NDI Optotrak motion capture system and AMTI force platforms in the walkway) at two time points, first within the week prior to their surgery, and second at approximately one year after surgery. At their post-operative visit, patients were asked to indicate their satisfaction with their knee prosthesis on a scale from zero to 100, with zero being totally unsatisfied and 100 being completely satisfied. Knee joint mechanics during gait at both time points were characterized by discriminant scores, the projection of their three-dimensional knee angles and moments during gait onto an existing discriminant model that was created to optimize separation of severe knee OA and healthy asymptomatic gait patterns. This discriminant model was created using data from 73 healthy participants and 73 with severe knee OA, and includes the magnitude and pattern features (captured with principal component analysis) of the knee adduction and flexion moment, and the magnitude of the knee flexion angle during gait. Larger discriminant scores indicate improved function toward healthy patterns, and smaller scores indicate more severe function. Associations between post-operative satisfaction and pre, post and change in discriminant scores were examined using Pearson correlation analyses. We also examined associations between satisfaction and pre-operative BMI, EQ5D and Oxford 12 scores, as well as changes in these scores from pre to post-TKA. Discriminant scores representing knee joint function during gait significantly improved on average after surgery (P =0.05). While overall knee joint function improved after primary TKA surgery, the amount of improvement in function was not reflected in post-operative patient satisfaction. However, the pre-operative function of the patient was negatively associated with satisfaction, indicating that patients with higher pre-operative function are overall less satisfied with their TKA surgery, regardless of any functional improvement due to the surgery. Interestingly, the only significant association with post-operative satisfaction was knee joint function, and the relationship between function and patient satisfaction following TKA appears to relate only to the baseline functional state of the patient, and not with functional improvement. This suggests that dissatisfaction post-surgery is more likely reflecting the unmet expectations of a higher functioning patient, and has implications for the need for improved understanding of pre-operative patient functional variability in TKA triage and expectation management

Background. The literature quotes up to 20% dissatisfaction rates for total knee replacements (TKR). Swedish registry and national joint registry of England and Wales confirm this with high volumes of patients included. This dissatisfaction rate is used as a basis for improving/changing/modernising knee implant designs by major companies across the world. Aim. We aimed to compare post TKR satisfaction rates for navigated and non navigated knees. Methods. This was a retrospective analysis of prospectively collected data. All patients undergo comprehensive preoperative evaluation and comprehensive consent process and same rehabilitation protocols are followed as standard practice. Two groups were established depending on whether surgery was performed with or without computer navigation. We included 229 patients in each group. There were nine bilateral cases in the navigated group giving a total of 238 knees. Both groups were similar at the time of surgery (navigated: 68 years (sd9);; BMI 32.46;; (sd5.19);; OKS: 42.2 (sd7.5);; non-navigated: 70 years (sd9);; BMI 32.36;; (sd5.26);; OKS: 42.4 (sd7.3)). The satisfaction rates are recorded as very satisfied, satisfied, unsure or dissatisfied. Results. Of the 238 navigated knees 227 (95.4%) were very satisfied or satisfied;; while of the 229 non-navigated knees 205 (89.5%) were very satisfied or satisfied. Only 3 (1.3%) navigated knees and 9 (3.9%) non-navigated knees were dissatisfied. Seven (2.9%) navigated knees and fifteen (6.6%) non-navigated knees were unsure. The navigated group showed better satisfaction (p=0.049) compared to the non-navigated group and better satisfaction than previously published satisfaction rates [3]. When combining dissatisfaction and unsure responses the navigated group again performed significantly better than the non-navigated group (p=0.021). Satisfaction rates were also compared with published literature, which suggest that 82–89% of TKA patients are satisfied and that navigation has no effect on satisfaction [3]. Our data for the non-navigated knees are similar to high end of the published data. This goes to show that comprehensive education of patients, high volume surgeons and elective arthroplasty unit along with comprehensive consent process can achieve best results. We have also shown that navigation influences satisfaction rates. There were no differences in 6 week OKS data with scores of 28.1 (sd= 8.0) and 28.8 (sd=7.8) for navigated and non-navigated groups(p=0.623), The same was also true for range of flexion/extension (92.1° [sd=13.4°& 91.3° [sd=14.1°, p=0.360) and length of hospital stay in days (median=5 [min=2, max=37], median=5 [min=2, max=19], p=0.959);; for navigated and non-navigated groups respectively. Of those navigated knees reported as ‘dissatisfied’ and ‘unsure’, 50.0% (5 knees) were due to pain in the knee. For non-navigated knees, 66.7% (16 knees) stated knee pain as the reason for being ‘dissatisfied’ or ‘unsure’. Conclusion. A modern elective arthroplasty service can deliver high satisfaction rates. Use of computer navigation further improves even the best conventional satisfaction rates. Industry should promote better surgical techniques rather than bringing out new implants to improve satisfaction rates in total knee replacements

Background. The posterior slope of the tibial component in total knee arthroplasty (TKA) has been reported to vary widely even with computer assisted surgery. In the present study, we analyzed the influence of posterior tibial slope on one-year postoperative clinical outcome after posterior-stabilized (PS) -TKA to find out the optimal posterior slope of tibial component. Materials and Method. Seventy-three patients with varus type osteoarthritic (OA) knees underwent PS-TKA (Persona PS. R. ) were involved in this study. The mean age was 76.6 years old and preoperative HKA angle was 14.3 degrees in varus. Tibial bone cut was performed using standard extra-medullary guide with 7 degrees of posterior slope. The tibial slopes were radiographically measured by post-operative lateral radiograph with posterior inclination in plus value. The angle between the perpendicular line of the proximal fibular shaft axis and the line drawn along the superior margin of the proximal tibia represented the tibial slope angle. We assessed one-year postoperative clinical outcomes including active range of motion (ROM), patient satisfaction and symptoms scores using 2011 Knee Society Score (2011 KSS). The influences of posterior tibial slope on one-year postoperative parameters were analyzed using simple linear regression analysis (p<0.05). Results. The average posterior tibial slope was 6.4 ± 2.0 °. The average active ROM were −2.4 ± 6.6 ° in extension and 113.5± 12.6 ° in flexion. The mean one-year postoperative patient satisfaction and symptom scores were 29.3 ± 6.4 and 19.6 ± 3.9 points respectively. The active knee extension, satisfaction and symptom scores were significantly negatively correlated to the posterior tibial slope (r = −0.25, −0.31, −0.23). Discussion. In the present study, we have found significant influence of the posterior tibial slope on the one-year postoperative clinical outcomes in PS-TKA. The higher posterior slope would induce flexion contracture and deteriorate patient satisfaction and symptom. We had reported that the higher tibial posterior slope increased flexion gap and the component gap change during knee flexion in PS-TKA. Furthermore, another study reported that increase of the posterior tibia slope reduced the tension in the collateral ligaments and resulted in the knee laxity at flexion. The excessive posterior slope of tibial component would result in flexion instability, and adversely affected the clinical results including patient satisfaction and symptom. Conclusion. In the PS-TKA for varus type OA knees, excessive tibial posterior slope was found to adversely affect one-year postoperative knee extension and clinical outcome including patient satisfaction and symptom. Surgeons should aware of the importance of tibial slope on one-year postoperative clinical results and pay more attentions to the posterior tibial slope angle not to be excessive

Despite the widespread success of total hip arthroplasty (THA), postoperative pain management remains a concern. Opioids have classically been administered for pain relief after THA, but their side effect profile, in addition to the cognizance of the growing opioid epidemic, has incited a shift toward alternative pain modalities. Although the nonsteroidal anti-inflammatory drug (NSAID) diclofenac is a promising addition, its impact on immediate THA outcomes has not previously been investigated. Thus, in the present study, we evaluate the effects of adjunctive diclofenac on: 1) postoperative pain intensity, 2) opioid consumption, 3) discharge destination, 4) length of stay, and 5) patient satisfaction in primary THA patients. A retrospective review was performed to identify all patients who underwent primary THA by a single surgeon between May 1 and September 31, 2017. Patients were stratified into a study group (n=25), who were treated with postoperative diclofenac in addition to the standard pain control regimen, and a control group (n=88), who did not receive adjunctive diclofenac. Repeated-measures analysis of variance (ANOVA)/analysis of covariance (ANCOVA) and chi-square/logistic regression analysis were used for continuous and categorical variables, respectively. Patients receiving adjunctive diclofenac were more likely to be discharged home than to inpatient facilities (O.R. 4.02, p=0.049). In addition, patient satisfaction with respect to how well and how often pain was controlled (p= 0.0436 and p=0.0217, respectively) was significantly greater in the diclofenac group. Finally, patients who received diclofenac had lower opioid consumption on postoperative days one and two (−67.2 and −129 mg, respectively, p=0.001 for both). The rapid growth of THA as an outpatient procedure has intensified the urgency of improving postoperative pain management. The present study demonstrates that THA patients receiving adjunctive diclofenac were more likely to be discharged home, had reduced opioid consumption, and experienced greater satisfaction. This will, in turn, decrease complications and total hospital costs, leading to a more cost-effective pain control regimen. In order to further investigate the optimal regimen, future studies comprising larger cohort, as well as a comparison of diclofenac to other NSAIDs, are warranted

INTRODUCTION. Patient-reported satisfaction is a critical measure in understanding the clinical success of total knee arthroplasty. Yet, satisfaction levels in TKA patients are generally lower than THA patients; and surgeon-patient agreeability regarding clinical success is typically in discordance. Thus, the purpose of this evaluation was to report on the one-year satisfaction data of a group of sensor-assisted TKA patients, and compare that data to the average satisfaction reported in literature, as measured by a meta-analysis. METHODS. One hundred and thirty five patients received TKA utilizing intra-operative sensing technology to evaluate soft-tissue balance as part of a prospective multicenter study. Patients were classified by two groups: “balanced” and “unbalanced”. Quantitative “balance” was defined as a mediolateral intercompartmental loading difference of ≤ 15 pounds; all loading exceeding 15 pounds was classified as “unbalanced”. At the one-year follow-up visit, a 7-question patient satisfaction survey was administered. The answering schema of this survey was modeled using a modified five-point Likert scale, ranging from “True” to “False” (or “Very Satisfied” to “Very Dissatisfied,” where appropriate). A meta-analysis of literature was performed and studies selected for inclusion in this analysis were required to meet the following criteria: all patients were in receipt of a primary TKA; satisfaction data was collected post-operatively; and the proportion of patients who were “satisfied” to “very satisfied” was statistically described. RESULTS. The overall satisfaction of sensor-assisted patients—indicating “satisfied” to “very satisfied”—at one-year, was 94.2%. The satisfaction levels, stratified by “balanced” and “unbalanced” patients, was 96.7% and 82.1%, respectively. The difference between the satisfaction of balanced and unbalanced patients is statistically significant (P=0.043). Twelve studies were included in the meta-analysis, which yielded a significant amount of homogeneity (B-F=3.048; homogeneity<0.001; df=11) [Figure 1]. The average satisfaction reported in literature for TKA patients is 81%, which is 16% lower than the balanced patients in the prospective patient group (P<0.001). It was found that, on average, 81% of TKA patients, as reported in the included meta-analysis literature, were “satisfied” to “very satisfied”. This represents a 16% decrease from the balanced cohort evaluated in this study (P=0.001). The average satisfaction reported in literature was more in agreement with the unbalanced cohort (82.1%). DISCUSSION. Quantifiably balanced TKA patients, verified by intraoperative sensors, exhibited significantly higher satisfaction than unbalanced patients at 1- year post-operatively (P<0.001). Specifically, the number of satisfied, balanced patients was 14.6% higher than satisfied unbalanced patients. The meta-analysis provided the opportunity to reasonably compare the average satisfaction across all included literature. The highest reported satisfaction among the evaluated literature was 90.3%, which is still 6.4% lower than the balanced patient group (P=0.045). The results of this study suggest that there may be a way to improve patient satisfaction in TKA. By verifiably balancing soft-tissues of the sensor-assisted TKA group, marked improvement in satisfaction scores was seen at one year. These trends toward better function and higher satisfaction are promising for the future of clinical success in TKA. Longer follow-up is ongoing and will be used to determine the longevity of this encouraging trend

Introduction. Patients-reported outcome measures (PROMs) have been reported as the important methods to evaluate clinical outcomes in total knee arthroplasty (TKA). The patient satisfaction score in Knee Society Score (KSS-2011) has been used in the recent literatures. Patient satisfaction was subjective parameter, and would be affected by multiple factors including psychological factors and physical conditions at not only affected joint but also elsewhere in the body. The question was raised regarding the consistency of patient satisfaction score in KSS-2011 to other PROMs. The purpose of this study was to investigate the correlation of patient satisfaction in KSS-2011 to other categories in KSS-2011 and to other PROMs including Forgotten Joint Score (FJS-12), EuroQol-5 Dimensions (EQ-5D) and 25-questions in Geriatric Locomotive Function Scale (GLFS-25). Material & Method. 83 patients over 65 years old with osteoarthritic knees were involved in this study. All patients underwent CR-TKAs (Persona CR. R. ). The means and ranges of demographics were as follows: age; 74.5 years old (65–89), Hip-Knee-Ankle (HKA) angle; 12.4 (−6.2–22.5) in varus. We asked patients to fulfill the questionnaire including KSS-2011, FJS-12, EQ-5D and GLFS-25 at 1-year postoperative follow-up visit. KSS-2011 consisted of 4 categories of questions; patient satisfaction (PS), symptoms, patient expectations (PE), functional activities (FA). We evaluated the correlation of PS to other PROMs using simple linear regression analyses (p<0.001). Results. The means and standard deviations of 1-year postoperative scores were as follows: PS; 28.5 ± 7.0, symptoms; 19.1 ± 4.3, PE; 11.2 ± 2.9, FA; 71.5 ± 16.6, FJS-12; 51.5 ± 18.6, EQ5D; 0.69 ± 0.10, GLFS-25; 25.7 ± 16.9. PSs were moderately positively correlated to other categories in KSS-2011(correlation coefficient (r): symptoms; 0.69, PE; 0.73, FA; 0.69). PSs were positively correlated to both FJS-12 and EQ5D (r: FJS-12; 0.72, EQ-5D; 0.67) and negatively correlated to GLFS-25(r; −0.74). Discussions. Patient satisfaction score positively correlated to the symptoms, patient expectation and functional activities in KSS-2011 with moderately high correlation coefficient. This meant the better pain relief and functional outcome improved patient satisfaction. Although there had be reported preoperative higher expectation would lead to poor patient satisfaction postoperatively, we interestingly found positive correlation between patient satisfaction and expectation at 1 year after TKA. Patient with the higher satisfaction tended to expect more in the future, on the other hand, unsatisfied patient with residual pain and/or poor function would resign themselves to the present status and reduced their expectation in our patient population. We have found patient satisfaction score in KSS-2011 significantly correlated to FJS-12 and GLFS-25 with strong correlation coefficient. This meant patient satisfaction could be considered consist to other PROMS in relatively younger patient with better functional status in this study. Conclusion. The patient satisfaction score in KSS-2011 was found to be consistent with moderately high correlations coefficient to other categories in KSS-2011 and other PROMs including FJS-12, EQ-5D, GLFS-25 at 1 year after (CR)-TKA.

Introduction. With the increasing burden of geriatric population in India, TKR is a very common procedure done these days. But as compared to western population the expectations of the people are different in our country. Indian patients want to sit cross legged and squat but can tolerate pain and limp better. So our population has different satisfaction levels after surgery. Keeping this in mind, post op evaluation should also include the performance as well as satisfaction levels. The factors affecting these parameters need to be studied. The current trend is to operate on younger people with more life expectancy and lesser co-morbidities but they have higher demands. Thus it is important to follow TKR patients for an extended time and to study their performance and satisfaction levels and the effect of pre op factors on these parameters. Objectives. To evaluate the patient's satisfaction in terms of postoperative pain and functional outcome. To identify preoperative characteristics predicting the postoperative outcome. MATERIAL AND METHOD. A study was done to analyse the satisfaction level, physical activity and quality of life after one year of TKR surgery using KOOS scoring system and DMC&H General Patient Questionnaire. Clinical data was recorded and a Performa was filled of 104 patients with 152 cemented total knee arthroplasty operated from June 2010 till December 2012 of who consented and underwent surgery at Dayanand Medical College & Hospital Ludhiana (India). Out of these, 56 were unilateral and 48 were bilateral cases. Results. There was a significant improvement in means of all the five KOOS subscale scores but mean difference of the pre op and post op KOOS sports/recreational scores was low as compared to other four subscales. There was no significant effect of sex, duration of symptoms, number of co-morbidities and BMI on post op KOOS outcome scores and patient's satisfaction. Younger age group patients had higher post op KOOS scores but older age group patients had higher post op satisfaction levels. Patients undergoing simultaneous bilateral TKR had higher post op KOOS scores and higher satisfaction levels as compared to patients undergoing unilateral TKR. Patients with higher preop functional and KOOS scores also had better postop satisfaction levels. Mean postoperative KOOS Scores had trend of higher scores in OA patients as compared to RA patients. Post op KOOS pain and ADL scores were comparable to patient's satisfaction level83.7% patients had excellent satisfaction level, 12.5% good, 1.9% fair and 1.9% poor satisfaction one year after surgery. CONCLUSION. Total knee replacement significantly improves patient's pain, symptoms, function and activities of daily living and knee related quality of life. Characters like sex, duration of symptoms, number of co-morbidities and BMI do not significantly affect the outcome. However, preop diagnosis, higher preoperative KOOS score, simultaneous bilateral replacements had possitive effect on postoperative KOOS score and satisfaction levels after 1 year follow up. In younger patients KOOS score improvement was better but satisfaction levels were lower

Introduction. Total Knee Arthroplasty (TKA) is a proven successful and cost-effective method to relieve pain and improve joint function and quality of life in patients with advanced knee arthritis. However, after a TKA, only 75 to 89% of patients are satisfied. Since patient satisfaction is one of the main objectives of elective orthopaedic surgery, it is important to investigate the reasons for dissatisfaction and develop remedial strategies. Objectives. The aims of the current project are to investigate patient satisfaction after TKA and establish physical, mental and social determinants of patient satisfaction and overall socio-economic costs associated with unsatisfactory outcome. The global objective is to identify patients most likely to benefit from primary TKA, establish optimal evidence-based indications and timing for TKA, and address the necessity to educate patients preoperatively towards realistic expectations or propose alternative therapies. Based on the results, a composite score for patient selection will be developed using objective and subjective parameters. Cut-off values for acceptable indications for TKA will be proposed. Methods. General determinants of patient satisfaction are first investigated in a retrospective and prospective survey of TKA. Expectations regarding the global benefit of TKA, postoperative pain and difficulties are evaluated. Psychological tests assessing the ability of patients to cope with pain are performed. Objective clinical and radiographic parameters, patient reported outcomes and satisfaction are compared between subgroups based on (1) patient intrinsic factors such as gender and age, BMI, co-morbidities, general physical and mental health, activity, level of education and socio-economic situation, (2) implant factors, (3) surgery and surgical experience related factors. Subsequently, a randomized controlled trial of 330 consecutive primary TKAs using 3 contemporary implants of different design concepts will be carried out. Evaluation will be double-blinded (immediately preoperative randomisation, patient blinded, postoperative observer blinded). In addition, a surgeon's assessment of subjective technical difficulty will be performed. A university/teaching hospital setting will be compared with a private hospital and the influence of the surgeon on the level of patient satisfaction will be assessed. Results. Intermediate evaluation of the study revealed extensive logistic difficulties in setting up such a large scale trial and in motivating patients, nursing and medical staff to participate and sustain the necessary commitment and discipline to collect all necessary data at all follow-up intervals. Patients often felt overwhelmed by a multitude of clinical scores and technical assessments leading to a decrease in study compliance and rapid loss to follow-up. Motivation proved easier in a smaller private hospital environment. At the university hospital, patient involvement was enhanced by a personalized approach with information sessions in small groups. The introduction of a new software system with direct patient input via touch screens or remote online completion of scores reduced the data input burden. Scores are examined for simultaneous digital answering of overlapping questions. Conclusions. A large scale trial to investigate longer term patient satisfaction after TKA and establish its determinants involves continuous motivation and sustained discipline of patients and staff. A personalized approach and digital patient reported outcomes prove to maximize data acquisition

Background. In recent literatures, medial instability after TKA was reported to deteriorate early postoperative pain relief and have negative effects on functional outcome. Furthermore, lateral laxity of the knee is physiological, necessary for medial pivot knee kinematics, and important for postoperative knee flexion angle after cruciate-retaining total knee arthroplasty (CR-TKA). However, the influences of knee stability and laxity on postoperative patient satisfaction after CR-TKA are not clearly described. We hypothesized that postoperative knee stability and ligament balance affected patient satisfaction after CR-TKA. In this study, we investigated the effect of early postoperative ligament balance at extension on one-year postoperative patient satisfaction and ambulatory function in CR-TKAs. Materials & Methods. Sixty patients with varus osteoarthritis (OA) of the knee underwent CR-TKAs were included in this study. The mean age was 73.6 years old. Preoperative average varus deformity (HKA angle) was 12.5 degrees with long leg standing radiographs. The knee stability and laxity at extension were assessed by stress radiographies; varus-valgus stress X-ray at one-month after operation. We measured joint separation distance (mm) at medial compartment with valgus stress as medial joint opening (MJO), and distance at lateral compartment with varus stress as lateral joint opening (LJO) at knee extension position. To analyze ligament balance; relative lateral laxity comparing to the medial, varus angle was calculated. New Knee Society Score (NKSS) was used to evaluate the patient satisfaction at one-year after TKA. We measured basic ambulatory functions using 3m timed up and go test (TUG) at one-year after surgery. The influences of stability and laxity parameters (MJO, LJO and varus angle at extension) on one-year patient satisfaction and ambulatory function (TUG) was analyzed using single linear regression analysis (p<0.01). Results. MJOs at knee extension one-month after TKA negatively correlated to patient satisfaction (r=−0.37, p<0.01) and positively correlated to TUG time (r=0.38, p<0.01). LJOs at knee extension had no statistically significant correlations to patient satisfaction and TUG. The extension varus angle had significant positive correlation with patient satisfaction (r=0.40, p<0.01). Discussions. In our study, we have found significant correlations of the early postoperative MJOs at extension to postoperative patient satisfaction and TUG one-year after CR-TKA. Our results suggested that early postoperative medial knee stabilities at extension were important for one-year postoperative patient satisfaction and ambulatory function in CR-TKA. Other interest finding was that postoperative patient satisfaction was positively correlated with extension varus angle. This finding suggested that varus ligament balance; relative lateral laxity to medial stability, was beneficial for postoperative patient satisfaction after CR-TKA. Intra-operative soft tissue balance had been reported to significantly affect postoperative knee stabilities. Therefore, with our findings, surgeons might be better to manage intra-operative soft tissue balance to preserve medial stability at extension with permitting lateral laxity, which would enhance patient satisfaction and ambulatory function after CR-TKA for varus type OA knee. Conclusion. Early postoperative medial knee stability and relative lateral laxity would be beneficial for patient satisfaction and function after CR-TKA

Total knee arthroplasty (TKA) patients are consistently reported to be less satisfied than total hip arthroplasty (THA) patients. A patient's perception of success of his/her own total knee is dictated by their levels of post-operative pain and function, and many return to follow-up visits with inexplicable pain and stiffness that contradict favorable radiographic results. Several of these chief complaints that contribute to dissatisfaction are associated with soft-tissue imbalance. Therefore, in an effort to thoroughly understand the post-operative impact of soft-tissue balance on satisfaction, a multicenter study was conducted to evaluate the satisfaction outcomes of quantifiably balanced patients. In this study, 102 sensor-assisted patients were followed out to 3 years. The intraoperative devices used in this study project kinetic loading (lbf.) and center of load location data, in real-time, to a screen. Because of the wireless nature of the intraoperative sensors, the patella can be reduced, and kinematic data can be evaluated through the range of motion. The target balance window that was used in this study has been previously reported in literature and includes: 1) a mediolateral differential of 15 lbf., through the ROM, and 2) Sagittal plane stability as determined by a posterior drawer analysis. A robust, face-validated satisfaction survey was administered at 3-year follow-up and included 7 questions with answers on a 5-point Likert scale. At 3 years, post-operatively, 97.2% of this patient group reported being “satisfied” to “very satisfied” with their procedure, in comparison to the 81% average TKA satisfaction reported in literature (df = 11). The comparative literature included annual satisfaction intervals from 1 to 5 years (n = 33,775) which is comparable to the interval reported in this patient group. The sensor-assisted patient group exhibited a 16% increase in the proportion of satisfaction over what is currently reported in the comparative literature (p = 0.001). Despite the success rate of TKA, unfavorable patient-reported satisfaction continues to present a problem for operative recipients and surgeons. Because satisfaction is dependent upon several variables – including pain, function, and activity levels – the satisfaction survey used in this study represents a more accurate account of patient perception than many traditional surveys. It was shown that sensor-balanced TKA patients exhibited a 16% increase in the proportion of those reporting being “satisfied” to “very satisfied”, over the average satisfaction reported in literature. Allowing the surgeon to quantitatively balance the soft-tissue envelope, dynamically, has continued to a significant decrease in the proportion of dissatisfaction
