RESUMEN
PURPOSE: To determine cutoff values for the Knee Society Scores (KSS) indicative of a categorical scale of medium-term outcomes. METHODS: One hundred and fifty-five patients who underwent primary cruciate-retaining TKA with a patellar button for osteoarthritis at a single-centre were assessed prospectively by the KSS and short-form Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) simultaneously at the 3-year follow-up. A validated categorization of the WOMAC score was used as a standard. The area under the curve (AUC) of receiver-operating characteristic (ROC) was used to assess the discriminative analysis accuracy of the, and the Youden index estimated the optimal cutoff point. RESULTS: For the KSS-knee score, the cutoff for an excellent outcome was 90.3 (AUC 0.75, 95% CI 0.71-0.78), 76.6 (AUC 76.6, 95% CI 0.70-076) for good, 64.8 (AUC 0.76, 95% CI 0.72-0.79) for fair, and < 64.8 (AUC 0.69, 95% CI 0.67-0.73) for poor. For the KSS-function score, the cutoff values were 85.2 (AUC 0.71, 95% CI 0.69-0.75), 73.1 (AUC 0.72, 95% CI, 0.70-0.76), 55.7 (AUC 0.70, 95% CI 0.71-0.74), and < 55.7 (AUC 0.68, 95% CI 0.66-0.72), respectively. CONCLUSION: A KSS-knee score ≥ of 90 was considered an excellent outcome, 77 good, 65 fair, and < 65 poor. For the KSS-function, those values are 85, 73, 56 and < 56, respectively. The treatment outcome's judgement may be clearer for the surgeon concerning a particular patient when using cutoff values for the scoring system employed, such as those determined in the present study.

PURPOSE: To evaluate the effectiveness of the quadriceps V-Y turndown augmentation for acute quadriceps tendon ruptures in the setting of TKA. METHODS: Prospective cohort of 22 patients with quadriceps rupture after TKA were compared with 44 matched patients underwent TKA without quadriceps rupture. Quadriceps ruptures were treated within three weeks after injury by suture augmented with Scuderi quadriceps V-Y turndown flap. Clinical evaluation was performed by the Knee Society Scores (KSS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and range of motion. Patellar height was assessed by the Blackburne-Peel ratio. RESULTS: The mean follow-up was 3.3 (range, 3-4) years. At the final follow-up, there were significant improvements in mean KSS scores in both groups (p = 0.001). In the quadriceps group, the mean flexion for all patients, but one with arthrodesis for periprosthetic infection, was 100.1° (range, 90-110°) and mean extensor lag was 7.1° (range, 0-20°). There were significant differences between groups in KSS scores (p = 0.001). Active flexion (p = 0.020) and extension (p = 0.001) were significantly better in the control group. However, there was no significant difference in WOMAC scores (p = 0.252) or patient satisfaction (p = 0.352). There were no quadriceps reruptures. One patient with periprosthetic infection was treated with arthrodesis. CONCLUSION: The quadriceps V-Y turndown is an effective and safe procedure for quadriceps ruptures in the setting of TKA. Although the functional outcomes were lower than in TKA patients with no quadriceps rupture, the quality of life and satisfaction were successful in the TKA patients with quadriceps rupture.

PURPOSE: There is a paucity of literature defining the minimal clinically important difference (MCID) for the Knee Society Scores (KSS) after total knee arthroplasty (TKA), and no data on the substantial clinical benefit (SCB) for KSS have been reported. The purpose of this study was to determine MCID and SCB for the KSS in patients with primary TKA. METHODS: The median age of patients was 71.6 (range 50-88) years, and 60.3% were females 507 patients with TKA were prospectively enrolled. Patients completed the KSS before surgery and at second postoperative year. The MCID values of the KSS were estimated using anchor-based method, distribution-based method and receiver operating characteristic (ROC) curve analysis with calculation of the area under curve (AUC). SCB was estimated using ROC. RESULTS: The MCID for KSS-knee score was 7.2 points by the anchor-based method, 7.2 by the distribution-based method, and using a ROC analysis the cutoff point was 8.9 points with an AUC of 0.75. For KSS-function score, the MCID values were 9.7, 6.3, and 10.3 (AUC 0.71), respectively. SCB values were 39.7 points (AUC 0.74) for the KSS-knee score, and 38.6 (AUC 0.76) for the KSS-function score. Logistic regression showed age and Charlson index to negatively affect the changes in KSS. CONCLUSION: Different methods for MCID calculation lead to different results. With the use of ROC curve analysis, patients with an improvement of at least 9 points for KSS-knee and 10 points for KSS-function scores experience a clinically important change, whereas those who have at least an improvement of 40 points for KSS-knee and 39 points for KSS-function scores experience a substantial clinical benefit. These findings can ensure clinical improvement from the patient's perspective and also aid in interpreting results from clinical studies. LEVEL OF EVIDENCE: III.

BACKGROUND: Many studies have analyzed the outcomes of total hip arthroplasty (THA) after failed intertrochanteric fracture fixation, but not after healed fracture. The objective is to investigate the influence of a prior healed intertrochanteric fracture fixation on the outcomes of a subsequent THA for osteoarthritis. METHODS: This is a matched retrospective cohort study of THA between 43 patients who suffered a prior intertrochanteric fracture successfully managed with internal fixation and 43 patients without prior hip fracture. Mean age was 73.6 vs 74.2 years. A conventional cementless THA was used in both groups. Functional outcome was assessed by the Harris hip score (HHS) and reduced Western Ontario and McMaster Universities Osteoarthritis Index questionnaire. Radiological assessment was also performed. RESULTS: Mean follow-up was 6.6 (range, 5-8) years. The mean operative time and blood transfusion rate were significantly higher in the fracture group (P = .001), but there was no significant difference in the length of stay. HHS significantly improved in both groups. At final follow-up, HHS was significantly higher in nonfracture group (P = .008), but the rate of patients with excellent and good outcomes was similar (P = .616). Western Ontario and McMaster Universities Osteoarthritis Index score at the final follow-up was not different between groups (P = .058). Complication rate was similar between groups. There were no revisions, dislocations, or loose implants in the study group. CONCLUSION: Cementless THA provided successful functional outcomes and implant durability at medium term in patients treated for osteoarthritis following healed intertrochanteric fracture fixation, comparable to those without prior fracture who underwent primary THA. Surgical complexity and complication rate were low.

BACKGROUND: The objective of the study was to analyze if the length of interval time between stages influenced functional and quality of life outcomes in patients with staged bilateral primary total knee arthroplasty (TKA). METHODS: This is a retrospective comparative study between 93 patients with an interval between stages of 6-8 months (6-month group), 112 of 12-14 months (1-year group), and 108 of 24-26 months (2-year group). Outcome variables were Knee Society scores, Western Ontario and McMaster Universities, Short Form, and patient satisfaction. RESULTS: Overall, the mean follow-up for the first TKA was 8.2 (range, 7-10) years, and for the second TKA, 6.7 (range, 5-10) years. At last follow-up, functional and patient-related outcomes were similar for both knees, regardless of the interval. However, mental score and patient satisfaction were significantly better for the second than for the first TKA in the 2-year group. Age did not correlate significantly with the functional scores but was significantly correlated with the mental score. CONCLUSION: The performing staged bilateral TKA with a wide interval between surgeries provided equivalent functional outcomes and quality of life for both knees. Postoperative outcomes were not affected by the length of the time interval between procedures or age. Our results can help the surgeon to inform the patients reliably about what they can expect in the delay of a second knee replaced. Thus, patients could make an informed decision.

BACKGROUND: Few studies have analyzed the outcomes of total knee arthroplasty (TKA) in patients with prior anterior cruciate ligament (ACL) reconstruction, and the reported outcomes are controversial. The purpose of this study is to assess if prior ACL reconstruction had any impact on the outcome of subsequent TKA. METHODS: A matched case-control study was conducted in patients who underwent TKA, including 37 with prior ACL reconstruction and 37 patients without ACL reconstruction. Preoperative and postoperative clinical and radiological data were collected from a prospective arthroplasty database with a minimum follow-up of 5 years. The mean age was 69.6 years, and 59.4% were men. The Knee Society scores, Short Form-12, and Western Ontario and McMaster Universities questionnaires were used for functional evaluations. Visual analogue scale 0-10 was used for patient satisfaction. RESULTS: The mean follow-up after TKA was 6.1 (range 5-7.3) years. Two patients in the ACL group developed knee stiffness requiring manipulation under anesthesia, while 1 patient in the control group suffered superficial wound infection. At last follow-up, no significant differences in functional or radiologic outcomes were found between both groups. The performance of TKA in ACL patients had increased technical difficulty and significantly longer time of surgery, but this had no influence on the outcomes. In the ACL group, 24 knees had technical difficulty in surgery. The main difficulty in most ACL patients was due to varus deformity and increased retraction of the medial soft structures which required progressive medial release. Other 2 knees had difficult knee exposure. One was an unexpected partial patellar tendon avulsion and the other required planned quadriceps snip. CONCLUSION: TKA was an effective procedure for patients with prior ACL reconstruction. The surgeon should be warned of the possible difficulties in the knee exposure and possible need of medial release to obtain an appropriate ligament balance. However, these additional procedures had no negative effect on the outcomes of TKA.

PURPOSE: The objective was to assess the ability of the volar locking plate to maintain the radiographic parameters over the time in elderly patients with complex intra-articular distal radius fractures. METHODS: Prospective cohort of 66 consecutive patients with mean age of 68 (range 60-81) years and AO type C fractures treated with volar locking plate. Radiographic measurements were performed pre and post-operatively at each follow-up. Clinical assessment was made by Patient-Rated Wrist Evaluation scores, Disabilities of the Arm, Shoulder and Hand score, range of motion, and grip strength. RESULTS: The mean post-operative follow-up was 31 (range, 24-47) months. The most difficult parameters to restore intra-operatively were volar tilt and radial height, while radial inclination and ulnar variance were restored in a high rate of patients. There was significant loss of reduction within four post-operative months in volar tilt (p = 0.001) and radial height (p = 0.029). Mean radiographic parameters had no changes from four months to final evaluation. At final follow-up, 50.1% of the patients had all radiographic parameters restored in comparison with the noninvolved wrist, but 83.3% had all radiographic parameters within a functional range (p = 0.001). No significant relationship between radiographic and functional outcomes was found (p = 0.474). CONCLUSIONS: This study found that volar locking plate fixation for displaced intra-articular distal radius fractures in elderly patients was an effective procedure to obtain success functional outcomes. Although reduction loss in volar tilt and radial height occurred within four first months, volar plate was able to maintain fracture stabilization with radiographic parameters within functional range over the time in most patients of these elderly patients.

PURPOSE: To compare outcomes after TKA for osteoarthritis between patients younger than 55 years and older patients. METHODS: A cohort of 61 patients aged 55 years or younger was prospectively matched for gender, body mass index and knee function with patients with median age of 66 (range 60-70) years. Clinical evaluation was performed by the Knee Society scores (KSS), reduced Western Ontario and McMasters Universities (WOMAC) and Short-Form 12 (SF12) questionnaires. Radiological evaluation was also performed. RESULTS: The median follow-up was 12 (range 10-14) years. Survival at 14 years was 96.7% (95% CI 92-100%) in the younger group and 98.2% (95% CI 95-100%) in the older group (n.s.). There was no deep infection or loosening of femoral or patellar component in either group. In the younger group, 2 patients required revision (aseptic tibial loosening at 8 years, and polyethylene wear at 10 years). In the older group, there was 1 revision (aseptic tibial loosening). Revision rate was not significantly different (n.s.). Multivariate analysis showed no significant relationship between revision and age, gender or BMI. At 5-year follow-up, there were no significant differences between groups in KSS knee or function, WOMAC pain or function, or SF12 physical or mental, but in the last evaluation there were better results in younger patients for KSS-function (p = 0.018), WOMAC-function (p = 0.028), SF12-physical (p = 0.001) and SF12-mental (p = 0.035), although these differences were not clinically relevant. A significant decline was noted for KSS-function in either group from 5-year to at last follow-up. CONCLUSIONS: The TKA survival in younger patients was comparable to older active patients, without increased complications or revisions at a minimum follow-up of 10 years. Primary hybrid TKA can provide successful pain relief, function and quality of life in younger patients than 55 years with osteoarthritis. TKA is a suitable option for these young patients with appropriate surgical indications. LEVEL OF EVIDENCE: II.

BACKGROUND: Clinical outcomes of total knee arthroplasty (TKA) in very older patients have been widely studied, but the available evidence on quality of life (QOL) is limited. The objective was to evaluate the impact of TKA on the QOL in octogenarian patients and assess whether the risk-benefit justified surgery. METHODS: Prospective study comparing 143 octogenarian and 149 septuagenarian patients. QOL was assessed with the Short Form-12 (SF-12) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaires and functional outcomes with the Knee Society score (KSS). Comorbidity, complications, pain, and satisfaction were also assessed. RESULTS: Mean postoperative follow-up was 3.2 years (range, 2-5 years). Comorbidities, medical complications, transfusion rate, and length stay were not different between groups (P < .05). Comorbidities and complications had no influence on the outcomes. There were no significant differences in preoperative knee KSS, WOMAC, or SF-12 mental scores, but octogenarians had significantly lower functional KSS (P = .003) and SF-12 physical scores (P = .005). At the last follow-up, there were no significant differences in KSS, WOMAC, and SF-12 physical scores (P < .05), but octogenarians had higher SF-12 mental (P = .030) and satisfaction (P = .031) scores. CONCLUSION: TKA provided pain relief, satisfaction, and improvement in QOL for octogenarian patients to the level of the septuagenarian patients. TKA was a suitable option for octogenarian patients with appropriate surgical indications and manageable risk.

BACKGROUND: The purpose of this study was to compare outcomes and complications after total knee arthroplasty (TKA) between end-stage renal disease (ESRD) patients and patients without renal insufficiency. METHODS: A retrospective case-control study with prospectively collected data was carried out to compare 15 ESRD patients with a matched cohort of 30 nonrenal patients. Clinical evaluation was performed by the Knee Society Scores (KSS) and reduced Western Ontario MacMasters University (WOMAC) questionnaire. Radiologic evaluation was also performed. RESULTS: The mean postoperative follow-up was 3.4 years (range, 2-6). In the ESRD, the mean hospital stay and transfusion rate were significantly higher than control group. Preoperatively and postoperatively, there were no significant differences in KSS-knee or WOMAC-pain scores, but KSS-function and WOMAC-function were significantly lower in the ESRD group. There was no significant difference between groups in mean gain of KSS-function (45.1 vs 43.2, P = .071), but there was a significant lower mean gain for WOMAC-function in the ESRD group (37.0 vs 44.0, P = .003). In the ESRD group, 3 patients presented medical complications which were treated successfully. There were 2 superficial infections and no deep infection. One patient died at 30 postoperative months. In the control group, there were no medical complications, infections, or deaths during the follow-up period. In ESRD group, there were 2 knees with radiolucent lines. In either group, there was no loosening or revision. CONCLUSION: TKA was a successful procedure for knee osteoarthritis in most ESRD patients. Dialysis patients may expect improvement in function after TKA, but the patients need to be informed of the possible risk of postoperative severe medical complications due to nature of their renal disease.

PURPOSE: The primary objective of this study was to evaluate the influence of the time on waiting list for total knee arthroplasty (TKA) on the post-operative satisfaction and patient-reported outcomes. METHODS: This was a prospective observational study of 192 patients followed for one year. Patients were pre and post-operatively assessed with the 12-item Short-Form, reduced Western Ontario MacMaster University, and Knee Society scores. In addition, the Hospital Anxiety and Depression scale was used at time of admission, and patient satisfaction on a five point Likert scale at one post-operative year. Univariate and multivariate analyses were performed. RESULTS: Patients waiting longer than six months had significantly worse pre-operative anxiety score as well as post-operative SF12 (both physical and mental) and KSS-function scores compared to those with a waiting time shorter than six months. Dissatisfaction rate was also higher in patients waiting longer than six months, and it was mainly influenced by pre-operative anxiety and depression. CONCLUSIONS: Waiting time longer than six months negatively influenced post-operative satisfaction and patient-related outcome at one year after TKA. These findings may have important clinical implications regarding the prioritization of patients on wait lists or for optimization of treatment while patients wait for surgery related to the management of the mental health and anxiety in order to reduce post-operative dissatisfaction and improve patient-reported outcomes.

BACKGROUND: The influence of smoking on the risk of periprosthetic joint infection (PJI) remains unclear. The objective was to explore the impact of smoking on PJI after primary total knee (TKA) and hip (THA) arthroplasty. HYPOTHESIS: Current smoking patients should have an increased risk of PIJ compared with nonsmoking patients. PATIENTS AND METHODS: A prospective registry-based observational cohort study was performed. A total of 4591 patients who underwent primary TKA (3076 patients) or THA (1515) were included. According to the smoking status at the time of arthroplasty, patients were classified as nonsmokers (3031 patients), ex-smokers (688), and smokers (872). Multivariate analysis included smoking status, age, gender, education level, body mass index, American Society of Anesthesiologists class, diagnosis (osteoarthritis, rheumatism), diabetes, chronic obstructive pulmonary disease, perioperative blood transfusion, site of arthroplasty (knee, hip), length of operation, and length of stay. RESULTS: There were PJI after 59 (1.9%) TKA and 27 (1.8%) THA (p=0.840). There were PJI in 47 (1.6%) nonsmokers, 12 (1.7%) ex-smokers, and 17 (1.9%) smokers (p=0.413). There were wound complications (delayed wound healing and superficial wound infection) in 34 (0.7%) nonsmokers, 9 (1.3%) in ex-smokers, and 17 (1.9%) in smokers (p=0.045). In multivariate analysis, only the female gender was a significant predictor of PJI (OR 1.3, 95% CI 1.1-2.4 [p=0.039]). Specifically, the categories of ex-smokers (OR 0.8, 95% CI 0.2-1.7 [p=0.241]) and smokers (OR 1.1, 95% CI 0.6-1.5 [p=0.052]) were not significant predictors. The 4-year arthroplasty survival with PJI as the endpoint was 99.1% (95% CI: 99.0-99.7) for nonsmokers, 99.0% (95% CI: 98.8-99.2) for ex-smokers, and 98.7% (95% CI: 98.2-99.0) for smokers was not significantly different between smoking status groups (p=0.318). DISCUSSION: Smoking was not identified as a significant predictor for PJI following primary TKA or THA. LEVEL OF EVIDENCE: III, prospective cohort study.
RESUMEN
INTRODUCTION: Treatment of the distal radius fracture in elderly remains controversial. The objective was to assess the outcomes of volar locking plate for displaced complete intra-articular distal radius fractures in elderly as compared to younger patients. HYPOTHESIS: The outcomes in elderly patients would be comparable with those in younger patients with a low rate of complications. MATERIAL AND METHODS: Non-randomised prospective comparative study between 70 patients older than 65 years and 46 younger patients with AO type-C fractures. The main outcome was Disabilities Arm, Shoulder and Hand (DASH) score. Secondary variables were Patient-Rated Wrist Evaluation (PRWE) score, range of motion, Visual Analogue Scale (VAS) for pain, and grip strength. Radiological measurements were also performed. RESULTS: The mean follow-up was 30.9 (range, 24-53) months. There were no significant differences in mean DASH, PRWE, VAS-pain, wrist motion or radiological parameters at final follow-up. Multivariate analysis showed that the functional outcomes were significantly influenced by baseline ulnar positivity greater than 3mm at baseline but not by age. DISCUSSION: The study hypothesis was confirmed. Surgical treatment with volar locking plate for displaced complete intra-articular fractures of the distal radius in elderly patients represents a safe and effective treatment alternative with similar early complication rate than in younger. LEVEL OF EVIDENCE: III, cohort study.

We compared outcomes in elderly patients with intra-articular distal radius fractures treated by closed reduction and plaster immobilization or open reduction and internal fixation with a volar plate. Ninety-seven patients older than 60 years were randomly allocated to conservative (47 patients) or surgical (50 patients) treatment. Over a 2-year period, we assessed patient-rated wrist evaluation score, DASH (disability arm, shoulder and hand) questionnaire, pain, wrist range of motion, grip strength, and radiological parameters. The functional outcomes and quality of life were significantly better after volar plating fixation compared with conservative treatment. We found that restoration of the articular surface, radial inclination, and ulnar variance affected the outcomes, but the articular step-off did not. Twenty-five per cent of the patients with conservative treatment had secondary loss of reduction. We conclude that surgical plating leads to better outcomes than conservative treatment for elderly patients with intra-articular distal radius fractures. LEVEL OF EVIDENCE: I.

PURPOSE: To analyze prospectively the influence of the timing of surgery on morbidity and mortality, and to assess whether the early surgery within 2 days admission may be a reliably healthcare quality indicator. METHODS: Prospective observational study of 628 patients age 60 or older who had been co-managed between surgeons and internists. Based on the literature, many potential factors influencing outcomes were collected to control confounding regard to surgery delay, complications and mortality. Multivariate logistic regression and Cox regression models were used to assess effects on the delay and mortality, respectively. RESULTS: Mean Charlson index was 2.3, and 284 patients had at least 3 comorbidities. Mean timing of surgery was 3.6 days (range 0-20). 418 patients were fit for surgery, of which 180 underwent surgery within 2 days. Delay for surgery more than 2 days was significantly associated with ASA >2, Charlson >2 and anticoagulant therapy. Medical complications were not significantly associated with delayed surgery more than 2 days. Mortality rate was 0.9% in-hospital, 3.4 at 1 month, 7.0% at 3 months, and 13.6% at 12 months. There were no significant differences in in-hospital, 3-month or 1-year mortality between patients operated within 2 days and those operated at 3-4 days, but delayed more than 4 days was associated with higher 1-year mortality. Likewise, patients readmitted within 30 days had higher in-hospital mortality. Excluding unfit for surgery patients at admission, there was no significant difference in 3-month or 1-year mortality between patients operated within 2 days and those with delayed surgery. CONCLUSIONS: Delaying surgery up to 4 days was not associated with higher morbidity or mortality rates. We recommend concentrating more on preoperative optimizing the condition of patient with sufficient medical treatment rather than being bound by a universal timing of surgery.
