Preoperative instillation of epinephrine and lidocaine can reduce surgical time in the endoscopic treatment of GTPS. / La instilación preoperatoria de epinefrina y lidocaína puede reducir el tiempo quirúrgico del tratamiento endoscópico del SDTM.

INTRODUCTION: Greater Trochanteric Pain Syndrome (GTPS) is a multifactorial clinical condition affecting the lateral area of the hip. Although conservative treatment shows good results, some patients may still require surgical bursectomy, which can be performed either openly or endoscopically. One of the main technical difficulties of the endoscopic procedure is intraoperative bleeding, which can hinder the medical team's vision and increase the operation time for endoscopic treatment of GTPS. HYPOTHESIS: An instillation of vasoconstrictors and local anesthetics before endoscopy will cause less intraoperative bleeding, which will translate into shorter surgical time. MATERIALS AND METHODS: A prospective cohort was retrospectively divided based on the use or absence of a preoperative instillation of physiological saline solution with epinephrine and lidocaine. Surgical time was measured in each procedure and compared between the two groups. RESULTS: One hundred thirty-nine hips from 139 patients were included in the analysis. One hundred two patients were included in the instillation group versus 37 in the control group. The surgical time was significantly shorter in the instillation group than in the control group, with an average (standard deviation) of 52.01 (14.71) and 72.30 (11.70) minutes, respectively (P<.001). CONCLUSION: The instillation of a physiological saline solution with epinephrine and lidocaine prior to the surgical treatment of GTPS is effective in reducing surgical times, likely due to a reduction in intraoperative bleeding. Future research should focus on more direct outcomes such as intraoperative blood loss and between different instillation protocols.

[Translated article] Efficacy of platelet-rich plasma in rotator cuff repair: Systematic review and meta-analysis.

OBJECTIVE: To analyse the efficacy and safety after the application of platelet-rich-plasma (PRP) as an adjuvant in arthroscopic rotator cuff repairs. MATERIAL AND METHODS: A bibliographic search of the literature of prospective studies with level of evidence one or two was carried out from January 2004 to December 2021, including studies that compare the functional and re-tear results after arthroscopic cuff repair rotator with or without PRP. RESULTS: A total of 281 articles were identified, of which 14 met the inclusion criteria. The overall re-rupture rate was 24%. In the PRP group, a decrease in the re-rupture rate and better functional results were demonstrated, although these differences were not significant. CONCLUSIONS: Adjuvant treatment with PRP has shown promising results, although there is not yet enough evidence to provide a clear advantage for routine use in clinical practice.
