ObjectivesNylon sutures and skin staples are used commonly in total knee arthroplasty (TKA) surgical wound closure. However, there is no study that compares the wound healing efficacy and patient satisfaction scores of both techniques in the same knee.MethodsWe randomised 70 patients who underwent primary TKA into two groups. In one group of 34 patients, the skin at the upper half of the wound was closed with skin staples and the lower half of the wound was closed with simple interrupted nylon sutures. In the other group of 36 patients, the skin at the upper half of the wound was closed with nylon stitches and the lower half of the wound was closed with skin staples. We recorded the wound closure time, pain score at the time of stitch removal, wound complication rate, patient satisfaction score, and the Hollander wound evaluation score at the post-operative periods of five days, 14 days, six weeks, three months, and six months. Each half wound was analysed separately.ResultsThe mean patient body mass index was 26.8 kg/m2 (standard deviation 6.3). A total of 70 nylon stitched wounds and 70 skin stapled wounds were analysed. There were no significant differences in wound complication rates, patient satisfaction score, and the Hollander wound evaluation score between both types of wounds (p > 0.05). The wound closure time for skin stapled wounds was significantly lower than the nylon stitched wounds (p < 0.001). However, the skin stapled wounds had a significantly higher pain score at the time of stitch removal (p < 0.001).ConclusionSkin staples and nylon stitches had comparable results with respect to wound healing and patient satisfaction in TKA wound closure in non-obese patients. The benefit of skin staples over nylon stitches was a decrease in operative time, but was more painful upon removal.Cite this article: V. Yuenyongviwat.

Background. Regular attendance of follow-up visits after total knee arthroplasty (TKA) is an important aspect of post-TKA patient care. Hence, this study was conducted to evaluate patient adherence to follow-up visits after TKA and analyze the factors that are associated with adherence to follow-up visits following TKA. Material and methods. This study was a retrospective study. The data of 411 knee osteoarthritis patients who had primary TKA were extracted from a single tertiary care hospital’s electronic database. All of the pa­tients underwent the same patient care protocol. The log-rank test was used for detecting differences in follow-up survival and influencing factors. Hazard ratios (HR) were calculated using Cox proportional hazard models. Results. The percentage of patients attending postoperative follow-up was 99.3 percent at 6 weeks, 61.1 percent after 1 year, 38.4 percent at 2 years, 32.1 percent after 3 years, and 24.6 percent at 4 years. Hazard ratios for loss to follow-up in patients younger than 65 years of age and those 65-75 years old, compared with those over 75 years old were 2.09 and 1.49, respectively (P<0.05). Patients classified as ASA II better adhered to follow-up visits than ASA III patients. (HR 0.71, P = 0.04). Lastly, HR in patients who lived at least 100 km away from the hospital compared with those who lived less than 100 km away was 0.78 (P = 0.033). Conclusions. 1. Adherence to follow-up visits after TKA was lower than we had expected. 2. The importance of follow-up visits should be emphasized to all patients, and especially in those who require special attention, such as patients who are at high risk of post-operative complications.

Background Osteoarthritis knee (OA) for patients whom had varus malalignment had higher peak adductor moment. Hip abductor strength played an important role in the decreasement of knee adduction moment. This study aimed to evaluate the effect of hip abductor exercises for patients who had medial compartment knees OA. Methods Patients who had medial compartmental OA knee were randomized into two groups. The first group performed hip abductor strengthening exercises, combined with quadriceps strengthening exercises; whereas, the second group performed standalone quadriceps strengthening exercises. Self-reported Knee Injury and Osteoarthritis Outcome Scores (KOOS) were collected by patients on follow-up visits. Results Eighty-six patients completed the trial. All KOOS subscales were significantly improved in both groups after 10 weeks of treatment. However, there was no significant difference in the scores between either group at 2–10 weeks after treatment. Nevertheless, the effects of exercise for pain, symptoms, function in daily living and knee-related quality of life were found to have faster improvement within the hip abduction exercise group compared to the control group (2 weeks faster; pain, function in daily living and knee-related quality of life, 4 weeks faster; symptoms.) Conclusion Since, adding quadriceps exercises could expedite improvement of less pain, symptoms, activity in daily living and quality of life faster than quadriceps exercises solely for a 2–4 weeks period. However, the effect size was small and there were no differences after this; hence, consideration of adding hip abductor exercises in the treatment protocol should be based on the patients and doctors appraisal.

Resumo Objetivo A aspirina (ácido acetilsalicílico, AAS) e a rivaroxabana são anticoagulantes que vêm ganhando popularidade devido à facilidade de uso na prevenção do tromboembolismo venoso (TEV) após artroplastia total do joelho (ATJ). Este estudo teve como objetivo avaliar a eficácia do AAS em comparação com a da rivaroxabana na profilaxia de TEV em pacientes submetidos a ATJ. Método Quarenta pacientes com osteoartrite primária do joelho, que seriam submetidos a ATJ, foram randomizados em dois grupos. No total, 20 pacientes do grupo AAS usaram aspirina oral, na dose de 300 mg/dia, para a profilaxia do TEV após ATJ; e 20 pacientes do grupo rivaroxabana receberam uma dose oral de 10 mg/dia. No 4° e 14° dias do pós-operatório, trombose venosa profunda (TVP) dos membros inferiores no lado da cirurgia foi detectada por meio de ultrassonografia duplex. Foram registradas outras complicações durante catorze dias. Resultados Não foram detectados achados positivos de TVP com a ultrassonografia duplex nos grupos de pacientes, e não se observou a ocorrência de embolia pulmonar. No total, 4 pacientes apresentaram equimose subcutânea no 4° dia do pós-operatório (2 pacientes no grupo AAS e 2 pacientes no grupo rivaroxabana; p = 1,0), e outros 4 pacientes, no 14° dia do pós-operatório (1 paciente no grupo AAS e 3 pacientes no grupo rivaroxabana; p = 0,292). Nenhum paciente da amostra apresentou hematoma da ferida cirúrgica, sangramento de órgão importante, infecção da ferida, ou necessidade de nova cirurgia. Conclusão A aspirina e a rivaroxabana apresentaram eficácia comparável na prevenção do TEV, sem aumentar a incidência de complicações da ferida e sangramento após ATJ.

Objective: Adhesive strips are used as the sole method for skin closure in many operations except total knee arthroplasty. The claims are decreased wound closure time, less tissue reaction, and lack of stitch marks. The purpose of this study was to compare the efficacy of closure using adhesive strips versus running subcuticular stitches. Methods: This study was a retrospective case-matched study. Running subcuticular stitches or adhesive strips were used for skin closure in 151 and 137 patients, respectively. All of the patients had an operation by a single surgeon and had the same patient care protocol. All of the patients were evaluated postoperatively for wound complication at 2 weeks, 6 weeks, and 3 months follow-up. Results: The wounds of most patients in both groups had healed. The incidence of superficial infection was not different between the groups (1.32% in the running subcuticular suture group and 1.46% in the adhesive strip group) ( p = 0.92). One case (0.66%) in the running subcuticular suture group had deep infection, which required reoperation ( p = 0.34). The patients in the running subcuticular suture group had higher unabsorbable sutures, which required further removal compared to the adhesive strip group ( p < 0.001). Conclusion: The use of adhesive strips is an effective skin closure method with a low rate of infection and skin complications. This technique is easy and there is no need for suture removal. Furthermore, there are no stitch marks and the cost of suturing is lower.

Background Medical education in this era has been disturbed by coronavirus disease. Our faculty has quickly adapted the curricula to online formats. The online format seems to be more advantageous in terms of content material and virtual activities, but the results of these adjustments will require subsequent evaluation. The aim of this study was to evaluate medical student expectations of online orthopedics learning that was created based on social constructivism theory. Materials and methods A cross-sectional survey was carried out to assess the fifth-year medical student expectations of our newly developed online orthopedics course during the outbreak. Constructivist Online Learning Environment Survey (COLLES) was applied for evaluating the expectations during orthopedic rotation. The survey contains six aspects based on social constructivist principles: relevance, reflection, interactivity, tutor support, peer support, and interpretation. All students responded to the preferred COLLES before starting the online course, and the actual COLLES was filled out when the online course was completed. Before and after attending the online course, the scores were compared and interpreted to assess student expectations. Results A total of 126 fifth-year medical students studied the online orthopedic course. The preferred COLLES were completed by 125 students, while 120 students replied to the actual COLLES. The overall scores from the post-course survey in all aspects were significantly higher than scores from the pre-course with P -value < 0.01. The comparison between the preferred and actual scores showed this online course fulfilled student expectations. Conclusion The outbreak of coronavirus disease 19 has disrupted medical student education. The online orthopedic learning course in our department has been developed to deal with the current situation. Using the various activities based on social constructivism theory in the online platform was able to fulfill medical student expectations.
