| 2 | Two-stage revision arthroplasty for coagulase-negative staphylococcal periprosthetic joint infection of the hip and knee显示文摘BACKGROUND Periprosthetic joint infections(PJIs)are frequently caused by coagulase-negative Staphylococci(CoNS),which is known to be a hard-to-treat microorganism.Antibiotic resistance among causative pathogens of PJI is increasing.Two-stage revision is the favoured treatment for chronic CoNS infection of a hip or knee prosthesis.We hypothesised that the infection eradication rate of our treatment protocol for two-stage revision surgery for CoNS PJI of the hip and knee would be comparable to eradication rates described in the literature.AIM To evaluate the infection eradication rate of two-stage revision arthroplasty for PJI caused by CoNS.METHODS All patients treated with two-stage revision of a hip or knee prosthesis were retrospectively included.Patients with CoNS infection were included in the study,including polymicrobial cases.Primary outcome was infection eradication at final follow-up.RESULTS Forty-four patients were included in the study.Twenty-nine patients were treated for PJI of the hip and fifteen for PJI of the knee.At final follow-up after a mean of 37 mo,recurrent or persistent infection was present in eleven patients.CONCLUSION PJI with CoNS can be a difficult to treat infection due to increasing antibiotic resistance.Infection eradication rate of 70%-80%may be achieved. | Ewout S Veltman Dirk Jan F Moojen Marc L van Ogtrop Rudolf W Poolman | 2019 | World Journal of Orthopedics2019，10，10： | 1 |
| 3 | Decision aids can decrease decisional conflict in patients with hip or knee osteoarthritis: Randomized controlled trial显示文摘BACKGROUND The interest in shared decision making has increased considerably over the last couple of decades.Decision aids(DAs)can help in shared decision making.Especially when there is more than one reasonable option and outcomes between treatments are comparable.AIM To investigate if the use of DAs decreases decisional conflict in patients when choosing treatment for knee or hip osteoarthritis(OA).METHODS In this multi-center unblinded randomized controlled trial of patients with knee or hip OA were included from four secondary and tertiary referral centers.Onehundred-thirty-one patients who consulted an orthopedic surgeon for the first time with knee or hip OA were included between December 2014 and January 2016.After the first consultation,patients were randomly assigned by a computer to the control group which was treated according to standard care,or to the intervention group which was treated with standard care and provided with a DA.After the first consultation,patients were asked to complete questionnaires about decisional conflict(DCS),satisfaction,anxiety(PASS-20),gained knowledge,stage of decision making and preferred treatment.Follow-up was carried out after 26 wk and evaluated decisional conflict,satisfaction,anxiety,health outcomes(HOOS/KOOS),quality of life(EQ5D)and chosen treatment.RESULTS After the first consultation,patients in the intervention group(mean DCS:25 out of 100,SD:13)had significantly(P value:0.00)less decisional conflict compared to patients in the control group(mean DCS:39 out of 100,SD 11).The mean satisfaction score for the given information(7.6 out of 10,SD:1.8 vs 8.6 out of 10,SD:1.1)(P value:0.00),mean satisfaction score with the physician(8.3 out of 10,SD:1.7 vs 8.9 out of 10,SD:0.9)(P value:0.01)and the mean knowledge score(3.3 out of 4,SD:0.9 vs 3.7 out of,SD:0.6)(P value:0.01)were all significantly higher in the intervention group.At 26-wk follow-up,only 75 of 131 patients(57%)were available for analysis.This sample is too small for meaningful analysis.CONCLUSION Providing patients with an additional DA may have a positive effect on decisional conflict after the first consultation.Due to loss to follow-up we are unsure if this effect remains over time. | Lode A van Dijk Antonius MJS Vervest Dominique C Baas Rudolf W Poolman Daniel Haverkamp | 2021 | World Journal of Orthopedics2021，12，12： | 1 |
| 4 | Improved patient reported outcomes with functional articulating spacers in two-stage revision of the infected hip显示文摘BACKGROUND Two-stage revision arthroplasty with an antibiotic-loaded spacer is the treatment of choice in chronically infected total hip arthroplasties.Interval spacers can be functional articulating or prefabricated.Functional results of these spacers have scarcely been reported.AIM To compare retrospectively the patient reported outcome and infection eradication rate after two-stage revision arthroplasty of the hip with the use of a functional articulating or prefabricated spacer.METHODS All patients with two-stage revision of a hip prosthesis at our hospital between 2003 and 2016 were included in this retrospective cohort study.Patients were divided into two groups;patients treated with a functional articulating spacer or with a prefabricated spacer.Patients completed the Hip Osteoarthritis Outcome Score and the EQ-5D-3L(EQ-5D)and the EQ-5D quality of life thermometer(EQVAS)scores.Primary outcomes were patient reported outcome and infection eradication after two-stage revision.The results of both groups were compared to the patient acceptable symptom state for primary arthroplasty of the hip.Secondary outcomes were complications during spacer treatment and at final follow-up.Descriptive statistics,mean and range are used to represent the demographics of the patients.For numerical variables,students’t-tests were used to assess the level of significance for differences between the groups,with 95%confidence intervals;for binary outcome,we used Fisher’s exact test.RESULTS We consecutively treated 55 patients with a prefabricated spacer and 15 patients with a functional articulating spacer of the hip.The infection eradication rates for functional articulating and prefabricated spacers were 93%and 78%,respectively(P>0.05).With respect to the functional outcome,the Hip Osteoarthritis Outcome Score(HOOS)and its subscores(all P<0.01),the EQ-5D(P<0.01)and the EQVAS scores(P<0.05)were all significantly better for patients successfully treated with a functional articulating spacer.More patients in the functional articulating spacer group reached the patient acceptable symptom state for the HOOS pain,HOOS quality of life and EQ-VAS.The number of patients with a spacer dislocation was not significantly different for the functional articulating or prefabricated spacer group(P>0.05).However,the number of dislocations per patient experiencing a dislocation was significantly higher for patients with a prefabricated spacer(P<0.01).CONCLUSION Functional articulating spacers lead to improved patient reported functional outcome and less perioperative complications after two-stage revision arthroplasty of an infected total hip prosthesis,while maintaining a similar infection eradication rate compared to prefabricated spacers. | Ewout S Veltman Dirk Jan F Moojen Rudolf W Poolman | 2020 | World Journal of Orthopedics2020，11，12： | 1 |
