Oxycodone-paracetamol tablet exhibits increased analgesic efficacy for acute postoperative pain, higher satisfaction and comparable safety profiles compared with celecoxib in patients underwent arthroscopic knee surgery.

This randomized, controlled study compared the efficacy and safety between oxycodone-paracetamol tablet and celecoxib for postoperative analgesia in patients who underwent arthroscopic knee surgery (AKS). Totally, 232 patients scheduled to undergo AKS were enrolled and were randomly assigned to either the oxycodone-paracetamol (OPT group) or the celecoxib group (CEL group). Pain at rest/motion (based on pain visual analog scale (VAS) score), rescue analgesia consumption, satisfaction level and adverse events were assessed after AKS. Pain VAS score at rest was decreased at 6 h, 12 h post-AKS in the OPT group compared with the CEL group. Similarly, pain VAS score at motion was reduced at 6 h, 12 h, 24 h post-AKS in the OPT group compared to the CEL group. Furthermore, both rescue analgesia rate (14.7% vs. 33.6%) and accumulated pethidine consumption (3.7 ± 8.9 mg vs. 14.0 ± 21.2 mg) were lower in OPT group compared with the CEL group. Patients satisfaction score was either at 24 h, 48 h in OPT group compared with the CEL group. Further subgroup analyses indicated that the effect of oxycodone-paracetamol versus (vs. celecoxib) on post-AKS management was more apparent in the elderly patients and male patients. In addition, the adverse events were well tolerable (including nausea, constipation, vomiting, drowsiness and dizziness) and were of no different between the two groups. In conclusion, oxycodone-paracetamol tablet presents increased analgesic efficacy for acute postoperative pain, with higher patient satisfaction and comparable safety profiles compared with celecoxib in patients underwent AKS.

Clinical Outcomes of Cannulated Screws versus Ring Pin versus K-Wire with Tension Band Fixation Techniques in the Treatment of Transverse Patellar Fractures: A Case-Control Study with Minimum 2-Year Follow-Up.

Purpose: K-wire with tension band (KTB) technique has long been the primary surgical method for transverse patella fractures; however, it also has shortcomings. This study is aimed at evaluating the three different techniques to see whether the cannulated screw tension band (CSTB) or ring pin tension band (RPTB) techniques could decrease complications and achieve better knee function compared with KTB. Methods: We conducted a retrospective comparison of the KTB, CSTB, and RPTB fixation techniques. We selected and reviewed 90 patients (30 patients in each fixation group) with follow-up at least 2 years. Duration of operation, intraoperative blood loss, mean healing time, visual analog scale score, range of motion, Böstman score, Iowa knee score, modified Lysholm rating scale, and postoperative complications were compared. Multivariate analyses were performed to identify the independent risk factors for fracture healing time, postoperative complications, and knee function recovery. Results: After adjusting for confounding factors, multivariate regression analysis revealed that CSTB was 0.26 times (95% CI: 0.08-0.86, p = 0.027) less likely to prolong fracture healing time, 0.20 times (95% CI: 0.06-0.64, p = 0.007) lesser risk of postoperative complications, and more than four times (95% CI: 1.41-13.56, p = 0.011) as likely to improve the knee function score compared with KTB. Besides, RPTB were also superior to KTB in reducing the incidence of postoperative complications (OR: 0.21, 95% CI: 0.07-0.64, p = 0.006) and improved knee function score (OR: 3.96, 95% CI: 1.30-12.08, p = 0.016); however, the CSTB group being more superior. In addition, AO/OTA C2 fractures (OR, odds ratio: 10.68, 95% CI: 1.30-87.70, p = 0.027) and high-energy fracture (OR: 8.78, 95% CI: 1.57-49.17, p = 0.013) were also associated with prolonged fracture healing time but not with postoperative complications and knee function. No significant differences in related indicators such as gender, age, BMI, AO/OTA classification, fracture side, injury mechanism, duration of operation, and intraoperative blood loss were detected among the three groups. Conclusion: This study demonstrated that the CSTB technique is superior to KTB and RPTB techniques in reducing the incidence of postoperative complications, and it also has advantages in accelerating fracture healing, achieving better VAS, ROM, and functional recovery. Further long-term large-sized prospective randomized trials are needed to evaluate the efficacy of the KTB in treating transverse patellar fractures.
