Use of cryotherapy in the postoperative management of paediatric anterior cruciate ligament reconstruction: a prospective randomised controlled trial.

To investigate the efficacy of cryotherapy in relieving postoperative pain and restoring knee range-of-motion (ROM) after paediatric anterior cruciate ligament reconstruction (ACLR). Patients undergoing primary ACLR were randomised into cryotherapy or non-cryotherapy groups. Those receiving cryotherapy were subjected to a standardised icing protocol. Icing schedules were used to assess compliance. Standard postoperative rehabilitation protocol was followed for both groups. Outcome measurements were visual analogue scale at rest and movement and knee ROM. Patients were assessed on postoperative day 1 (POD1), 1, 4 and 6 weeks. Twenty-one out of 42 patients received cryotherapy. Both groups were similar in demographics, surgical technique and use of intraoperative anaesthesia. Patients in the cryotherapy group reported lower overall mean pain scores throughout the study duration at rest (0.61 ±â€…1.70, 95% CI = 0.23-0.99 vs. 1.06 ±â€…2.03, 95% CI = 0.60-1.53) and on movement (2.19 ±â€…2.68, 95% CI = 1.59-2.79 vs. 3.13 ±â€…2.75, 95% CI = 2.51-3.75; P = 0.032). Knee flexion in the cryotherapy group showed better recovery of knee flexion from week 4 onwards. Improvement of knee flexion from POD1 is statistically significant at week 6 (98.7 ±â€…19.1°, 95% CI = 89.5-107.9 vs. 65.4 ±â€…49.9°, 95% CI = 42.7-88.1; P = 0.010) and overall mean (71.2 ±â€…35.9°, 95% CI = 61.2-81.1 vs. 45.3 ±â€…55.5°, 95% CI = 30.4-60.2; P = 0.005). The cryotherapy group reported statistically significant better degree of overall mean knee extension (1.2 ±â€…3.3°, 95% CI = 0.5-2.0 vs. 2.6 ±â€…4.6°, 95% CI = 1.6-3.7; P = 0.032). The use of cryotherapy in postoperative ACLR recovery in paediatrics is a simple yet effective measure resulting in short-term pain relief and improvement in knee flexion.

Both Adjustable and Fixed Loop Hamstring Tendon Graft Fixation Have Similar Clinical and Patient-Reported Outcomes in Anterior Cruciate Ligament Reconstruction.

Purpose: This study aims to compare the outcomes of fixed-loop device (FLD) vs adjustable-loop device (ALD) graft fixation with up to 2-year follow-up in patients undergoing primary anterior cruciate ligament reconstruction (ACLR) in a predominantly Asian setting. Methods: Prospectively collected outcome measures as well as clinical records of patients who underwent primary ACLR using either FLD or ALD fixation of hamstring tendon autograft performed by a single surgeon were reviewed. The surgeon in this study used a fixed-loop device from 2018 to 2019 and then changed to adjustable loop from 2019 to 2020. Suspensory fixation was performed on the femoral side, and aperture (interference screw) fixation was performed on the tibial side. Outcome measures included knee range of motion, KT-1000 arthrometer testing, Lysholm knee score, and Tegner activity scale. Patients were assessed preoperatively and postoperatively at regular intervals of 6, 12, and 24 months. Results: A total of 105 patients were identified. Forty-six were excluded due to incomplete follow-up data, so 59 patients with full 2-year follow-up were included in the final study group. Both groups (FLD vs ALD) were similar in demographics except for age (P = .042). Out of 105, there were 59 patients remaining in the study group with 2-year follow-up data. No significant differences were observed between the 2 groups at all respective testing intervals. Conclusions: FLDs and ALDs for suspensory fixation of hamstring tendon autograft in ACLR had similar clinical outcomes with a minimum of 2-year follow up. There is no evidence of graft loosening from loop lengthening. Level of Evidence: Level III, retrospective comparative trial.

Weber Ankle Fracture Classification System Yields Greatest Interobserver and Intraobserver Reliability Over AO/OTA and Lauge-Hansen Classification Systems Under Time Constraints in an Asian Population.

No previous studies have evaluated the intra- and interobserver reliability between the Weber, Lauge-Hansen and AO Foundation/Orthopaedic Trauma Association (AO/OTA) classification systems under time constraints. This study compares the interobserver and intraobserver reliability of the aforementioned classification systems under simulated time constraints. Anteroposterior and lateral radiographs of ankle malleolar fractures from 80 consecutive patients from 2015 to 2016 were classified by 2 independent observers according to Weber, Lauge-Hansen and AO/OTA. Classifications were conducted over 4 successive weeks under timed (25-seconds) and untimed conditions, with 1-week gaps between each classification. Cohen's kappa and percentage agreement were calculated. Cohen's kappa for interobserver agreement ranged 0.67 to 0.67 and 0.59 to 0.73 for untimed and timed classifications for Weber; 0.38 to 0.47 and 0.44 to 0.50 for Lauge-Hansen; 0.28 to 0.49 and 0.13 to 0.37 for AO/OTA. Intraobserver agreement ranged from 0.83 to 0.85 and 0.78 to 0.79 for untimed and timed classifications for Weber; 0.46 to 0.65 and 0.59 to 0.73 for Lauge-Hansen; 0.42 to 0.63 and 0.40 to 0.51 for AO/OTA. Based on the Landis and Koch's benchmark scale, there was substantial agreement in the inter- and intraobserver variables for Weber; moderate agreement in inter- and intraobserver variables for Lauge-Hansen; fair and moderate agreement in inter- and intraobserver variables respectively for AO/OTA. Interobserver and intraobserver reliability was the most substantial for Weber, followed by Lauge-Hansen and AO/OTA. Time constraint did not have a statistically significant effect on the reliability of classifications. We recommend concurrent usage of the Weber and Lauge-Hansen system, since they demonstrate the greatest reliability and reproducibility, and confer better understanding of the fracture type, respectively.

Forecasting the rate of hand injuries in Singapore.

PURPOSE: This study aims to analyse the correlation between the incidence rate of hand injuries and various major economic indicators in Singapore. We hypothesise that the number of hand injuries is correlated to activity in the construction and manufacturing industries in Singapore. METHODS: Twenty thousand seven hundred sixty-four patients who underwent hand surgeries in a tertiary institution between 2012 to 2018 were reviewed. Two independent, blinded observers extracted the frequency of hand surgeries performed from Electronic Medical Records. Economic indicators pertinent to Singapore's economic activity were collected and smoothed by simple moving average of the prior 3 months. Results were analysed using IBM SPSS v25.0. RESULTS: Significant independent univariate variables were Purchasing-Manager-Index and Industrial-Production-Index. Multiple linear regression of quarterly reported figures showed that Total-Livestock-Slaughtered, Total-Seafood-Handled, Purchasing-Manger-Index, Industrial-Production-Index, Gas-Tariffs, Construction-Index, Consumer-Price-Index, Total-Air-Cargo-Handled, Total-Container-Throughput, Total-Road-Traffic-Accident-Casualties, Food-&-Beverage-Services-Index were significantly correlated (p < 0.05) with hand injuries, with R2 = 62.3%. CONCLUSION: Quarterly economic indicators from major economic industries can be used to predict the incidence of hand injuries with a 62.3% correlation. These findings may be useful for anticipating healthcare resource allocation to treat hand injuries. TYPE OF STUDY AND LEVEL OF EVIDENCE: Economic and decision, Level II.

Robotic versus laparoscopic ventral hernia repair: a systematic review and meta-analysis of randomised controlled trials and propensity score matched studies.

PURPOSE: There has not been a consensus on the superiority of a surgical approach for minimally invasive ventral hernia repair. This systematic review and meta-analysis (SRMA) aims to compare clinical, and patient-reported outcomes of robotic-assisted ventral hernia repair (rVHR) to traditional endo-laparoscopic ventral hernia repair (lapVHR). METHODS: We searched PubMed, EMBASE, Cochrane and Scopus from inception to 16th March 2021. We selected randomised controlled trials and propensity score matched studies comparing rVHR to lapVHR. A meta-analysis was done for the outcomes of operative time, length of hospital stay, open conversion, recurrence, surgical site occurrence and cost. RESULTS: A total of 5 studies (3732 patients) were included in the qualitative and quantitative synthesis. Significantly shorter operative times were reported with the lapVHR as compared to rVHR (weighted mean difference (WMD): 62.52, 95% CI: 50.84-74.19). There was also significantly less rates of open conversion with rVHR as compared to lapVHR (WMD: 0.22, 95% CI: 0.09-0.54). No significant differences in patient-reported outcomes that was discernible from the two papers that reported them. CONCLUSION: Overall, rVHR is comparable to lapVHR with longer operative times but less open conversion. It is, therefore, important to have proper patient selection to maximise the utility of rVHR.
