Clinical Impact of Active Inflatable Insulation in Older with Undergoing Knee Arthroplasty.

Objective: This study aimed to explore the safety and effectiveness of active inflatable insulation in older patients who underwent knee arthroplasty. Methods: A total of 210 patients who came to our hospital for knee arthroplasty between November 2020 and December 2021 were selected for the study. They were randomly divided into a control group and two experimental groups, i.e., the intraoperative active warming (IOAW) group and the perioperative active warming (POAW) group, with 70 patients in each group. IOAW measures are taken to reduce heat loss during surgery and help maintain core temperature. POAW measures were taken to reduce the heat loss during surgery and help maintain the core temperature. The core body temperature, incidence of hypothermia, chills, bleeding volume (P = .043), extubation and awakening time, blood routine, and coagulation function of the patients in the three groups were compared. Results: The core body temperature in the POAW group was higher than that in the IOAW and control groups. The awakening and extubation times in the POAW group were shorter than those in the IOAW and control groups. The incidences of hypothermia, chills and intraoperative bleeding in the POAW group were lower than those in the IOAW and control groups. Conclusion: Perioperative active inflatable insulation for older patients undergoing knee arthroplasty can effectively protect the core body temperature, reduce the incidence of perioperative hypothermia, and reduce related complications. This measure is beneficial for the postoperative recovery of patients and provides a reference for active inflatable insulation measures for clinical knee arthroplasty.

Music Intervention to Orthopedic Patients: A Possible Alternative Solution to Control Pain.

Aims and Objective. Pain is a common problem associated with postoperative orthopedic patients; the current study is aimed at evaluating music intervention as an alternative method to control pain. Methodology. The experimental design of the current study was comparative, descriptive, and quasi-experimental. 38 postoperative orthopedic patients were equipped with pocket-size MP3 players with prerecorded music tracks (instrumental and lyrical) in Hindi, English, and Urdu. After that, pre-post-pain scores were recorded with the help of designed brief patient logs. Ultimately, a satisfactory survey was completed at discharge. Major Findings. It was found that during the intervention of music, the pain was significantly reduced from 5.40 to 2.98. There was a slight relationship between listening time and pain relief. It was also found that the feedback was extremely positive and each patient suggested the use of music to others with 96.6% recommendation. Conclusion. From the current study, it was found that music intervention can be beneficial to postoperative patient pain control. Further, it is hoped that the findings of the current experimental work will lead to improvements in the care of postoperative patients.

Reliability and concurrent validity of angle measurements in lower limb: EOS 3D goniometer versus 2D manual goniometer.

BACKGROUND: In clinical routine, preoperative radiographic assessment of lower extremity geometry relies on conventional X-rays. However, the plane goniometric measuring has several limitations in accurately locating anatomical landmarks. The purpose of this study is to propose a fast and accurate 3D-reconstruction-method based on biplanar X-rays with clinical measurements assessment in standing position. METHODS: 50 candidates for HTO or DFO with deformity of the lower extremities were included in this study. Biplanar X-rays were performed using the EOS imaging system in conventional double-stance full weight-bearing position (DS) and shifted-foot standing position (SF). The results of hip-knee-ankle angle (HKAA), lateral distal femoral angle (LDFA), and medial proximal tibial angle (MPTA) were evaluated by either 2D manual goniometer (MG) based on X-ray in DS standing position or 3D-reconstruction goniometer based on X-rays in SF standing position. RESULTS: For the reproducibility study, MG and EOS goniometer were both reliable in repeated measures of HKAA, LDFA, and MPTA, with average concordance correlation coefficients (CCCs) all above 0.910. The agreements between MG and EOS measurements were high for HKAA and LDFA with CCCs all above 0.90, while the agreement was low for MPTA with CCC below 0.75. Further linear regression model analysis also revealed a significant correlation between MG and EOS measurements for HKAA (all R2 ≥ 0.93) and LDFA (all R2 ≥ 0.90), but not for MPTA (all R2 ≤ 0.522). CONCLUSION: In comparison with the traditional 2D manual goniometer, EOS 3D reconstruction based goniometric measuring could provide equivalent results of HKAA and LDFA, and potentially a more accurate result of MPTA. These findings suggest that EOS 3D reconstruction based goniometric measuring is suitable for preoperative evaluation and planning for HTO/DFO. However, future improvements of the 3D reconstruction method are needed for better detection of the femoral condyles and tibial plates without the requirement of shifted-foot standing position. THE TRANSLATIONAL POTENTIAL OF THIS ARTICLE: EOS 3D reconstruction based goniometric measuring could provide equivalent or even more accurate results of HKAA, LDFA, and MPTA, in comparison with the traditional 2D manual goniometer, making it suitable for preoperative evaluation and planning for HTO/DFO.
