Ultrasound-guided genicular nerve radiofrequency (RF) procedures are of interest in the management of chronic knee pain. A wide variety of demographic, clinical, and procedural characteristics can affect treatment success. This study aimed to determine predictive factors to provide superior treatment outcomes.The demographic, clinical, and technical data of patients who received genicular nerve RF for knee pain between September 2016 and September 2021 were evaluated. A positive outcome was defined as at least 50% pain relief on a pain score for at least 6 months. Logistic regression analysis was performed to determine the factors associated with a successful response to genicular RF.Among 206 patients who underwent genicular RF, 62% of the patients reported successful outcomes at 6 months. In the multivariate model, targeting 5 nerves (odds ratio [OR], 6.184; 95% confidence interval [CI], 2.291-16.690;Clinical and technical factors associated with better treatment outcomes were ultimately targeting more nerves, performing prognostic block, no opioid use, and no depression. These results are expected to be considered when selecting patients for genicular RF.

ObjectivesGenicular nerve radiofrequency procedures increasingly are being performed to treat chronic pain due to knee osteoarthritis. Targeting additional sensory nerves and improving target identification by using ultrasound guidance could improve treatment success. The aim of this study was to compare the effectiveness of targeting only the traditional genicular nerves versus targeting the traditional genicular nerves plus 2 additional sensory nerves in ultrasound-guided genicular nerve radiofrequency procedures in patients with chronic knee osteoarthritis.MethodsA total of 80 patients were randomized into 2 groups. Patients in the 3-nerve-targeted group received a genicular radiofrequency procedure in which the traditional genicular nerves were targeted: the superior lateral, superior medial, and inferior medial nerves. The 5-nerve-targeted group received a genicular radiofrequency procedure in which the recurrent fibular and infrapatellar branches of the saphenous nerve were targeted in addition to the traditional genicular nerves. The numeric rating scale, Short Form-36, Western Ontario and McMaster Universities Arthritis Index, Quantitative Analgesic Questionnaire, and patient satisfaction were evaluated before treatment, at week 1 after treatment, and at months 1, 3, and 6 after treatment.ResultsBoth techniques provided significant pain reduction and functional improvement up to 6 months after the procedure (P ConclusionsThe ultrasound-guided 5-nerve-targeted technique is a safe method and a more effective therapeutic procedure than the traditional 3-nerve-targeted technique for chronic knee osteoarthritis.Trial registrationwww.ClinicalTrials.gov ID: NCT05073887.

Study Objective: The application of regional anesthesia techniques as a component of multimodal analgesia in knee arthroscopic surgeries increases the quality of postoperative analgesia. Adductor canal block (ACB) is an effective “motor sparing” analgesia technique used in knee surgeries. In this study, we aimed to evaluate the efficacy of two different concentrations of local anesthetic mixtures in terms of postoperative analgesia in patients undergoing knee arthroscopic intervention compared to each other and the control group. Design: Prospective, randomized, controlled, blinded Setting: Tertiary hospital Patients: A total of 60 patients (ASA I-II) were evaluated in three groups, with 20 in each group. Interventions: Standardized postoperative analgesia was planned for all groups. In addition, ultrasound guided ACB (same volume / two different concentrations of bupivacaine-0.25% vs 0.16%) was applied to the experimental groups. Measurements: Tramadol consumption, rescue analgesic requirement and Numeric Rating Scores (NRS). Main Results: Tramadol requirement in the first 24 hours was significantly higher in the control group (209.5±23.27 mg),(p

Adductor canal block (ACB) is an effective "motor sparing" analgesia technique used in knee surgeries. This study aimed to evaluate the efficacy of ACB using two different concentrations of local anaesthetic in terms of analgesic requirements and pain density in patients undergoing knee arthroscopy.
