The duration of postoperative analgesic use after total knee arthroplasty and nomogram for predicting prolonged analgesic use
BackgroundTotal knee arthroplasty is currently a reliable treatment for end-stage knee osteoarthritis. However, chronic postsurgical pain (CPSP) is substantially thought to reduce patient satisfaction. NSAID-based oral analgesics were used to manage CPSP, but research on the duration of postoperative analgesic use (DAU) and prolonged analgesic use (PAU) are presently scarce.MethodsPreoperative, perioperative, and one-year or above postoperative follow-up data were collected from 162 patients who underwent total knee arthroplasty between 1 June 2018 and 1 March 2019, and the DAU and the discontinuation time of each patient after discharge were recorded. Observational statistical analysis, diagnostic test, and predictive nomogram construction were performed on the collected data.ResultsThe 3-month DAU has good diagnostic utility for poor outcome of postoperative months twelve (POM12). The constructed nomogram shows that gender, preoperative Numeric Rating Scale (NRS) movement pain scores, duration of surgery, postoperative days three (POD3) moderate to severe movement pain, and POD3 pain rescue medication were significant prognostic predictors of PAU after discharge. The area under the curve (AUC) of the 3-month, 6-month, and 12-month nomogram receiver operating characteristic (ROC) curves were calculated to be 0.741, 0.736, and 0.781.ConclusionPAU was defined as more than three months of NSAID-based oral analgesic use after TKA. Prognostic predictors of PAU after TKA were identified, and visualized nomogram was plotted and evaluated. The evaluation indicated that the prediction model had the good predictive ability and was a valuable tool for predicting PAU after discharge
Clinical outcomes of arthroscopic surgery for external snapping hip
Abstract Background Studies have reported on the arthroscopic technique for release of external snapping hip syndrome. However, no study with large sample size has been reported for arthroscopic surgery. Methods Patients with 229 bilateral and 19 unilateral external snapping hips were treated from January 2012 to June 2013. After locating the contracture position, arthroscopic surgery was performed accordingly. Preoperative and postoperative angles were compared. Results Comparing range of motion, all patients obtained higher adduction and flexion angles. At postoperative follow-up of 24 months, the adduction angle was improved from −14.4 ± 5.14 to 35.7 ± 4.21 for type I, from −31.2 ± 5.22 to 31.7 ± 2.84 for type II, from −49.0 ± 3.47 to 21.6 ± 3.43 for type III, and from −64.5 ± 4.65 to 18.3 ± 3.10 for type IV (P < 0.001). Similarly, the flexion angle was also significantly improved for all the four types (P < 0.001). Excellent ratio and satisfaction rate were good in types I and II. All the clinical features were cured after arthroscopic surgery. Conclusions Arthroscopic surgery could be an effective procedure for external snapping hip, due to less operating time, small scar, fast postoperative recovery, and complete contracture release

Are Platelet-Rich Products Necessary during the Arthroscopic Repair of Full-Thickness Rotator Cuff Tears: A Meta-Analysis
<div><p>Background</p><p>Platelet-rich products (PRP) are widely used for rotator cuff tears. However, whether platelet-rich products produce superior clinical or radiological outcomes is controversial. This study aims to use meta-analysis to compare clinical and radiological outcomes between groups with or without platelet-rich products.</p><p>Methods</p><p>The Pubmed, Embase, and Cochrane library databases were searched for relevant studies published before April 20, 2013. Studies were selected that clearly reported a comparison between the use or not of platelet-rich products. The Constant, ASES, UCLA, and SST scale systems and the rotator cuff retear rate were evaluated. The weighted mean differences and relative risks were calculated using a fixed-effects model.</p><p>Results</p><p>Seven studies were enrolled in this meta-analysis. No significant differences were found for the Constant scale (0.73, 95% CI, −1.82 to 3.27, P = 0.58), ASES scale (−2.89, 95% CI, −6.31 to 0.53, P = 0.1), UCLA scale (−0.79, 95% CI, −2.20 to 0.63, P = 0.28), SST scale (0.34, 95% CI, −0.01 to 0.69, P = 0.05), and the overall rotator cuff retear rate (0.71, 95% CI, 0.48 to 1.05, P = 0.08). Subgroup analysis according to the initial tear size showed a lower retear rate in small- and medium-sized tears (0.33, 95% CI, 0.12 to 0.91, P = 0.03) after platelet-rich product application but no difference for large- and massive-sized tears (0.86, 95% CI, 0.60 to 1.23, P = 0.42).</p><p>Conclusion</p><p>In conclusion, the meta-analysis suggests that the platelet-rich products have no benefits on the overall clinical outcomes and retear rate for the arthroscopic repair of full-thickness rotator cuff tears. However, a decrease occurred in the rate of retears among patients treated with PRP for small- and medium-sized rotator cuff tears but not for large- and massive-sized tears.</p><p>Level of Evidence</p><p>Level II</p></div
