Total knee arthroplasty (TKA) is an effective surgical treatment for advanced disease, but many patients continue to suffer from chronic post-surgical pain (CPSP). In recent years, minimally invasive techniques targeting peripheral nerves have been explored. Cryoanalgesia of the genicular nerves (GNCryo) is one such intervention that disrupts sensory input by applying extremely low temperatures to the target nerves, potentially leading to sustained pain relief without the need for neurodestructive heat lesions. This study aims to evaluate the effectiveness of ultrasound-guided GNCryo in patients with chronic knee pain due to primary OA or CPSP after TKA.</p><p><strong>Methods: </strong>This retrospective, single-center study included 90 patients who underwent GNCryo between September 2021 and February 2023. Inclusion criteria were patients over 18 years of age, symptomatic knee OA or CPSP after TKA, and a positive response (≥ 50% pain relief) to diagnostic genicular nerve blocks. Ultrasound guidance was used to optimize needle placement and reduce complications. Clinical outcomes were assessed at baseline and at 1, 3, 6, and 9 months post-procedure. Outcome measures included the Visual Analog Scale (VAS, 0-10) for pain intensity, the Western Ontario and McMaster Universities Arthritis Index (WOMAC, 0-100) for assessing pain, stiffness, and physical function related to OA, the Douleur Neuropathique en 4 Questions (DN4, 0-10) for neuropathic pain, and the EuroQol 5-Dimension (EQ-5D, 0-100) for quality of life.</p><p><strong>Results: </strong>Ninety patients completed the 9 months follow-up. The median VAS score decreased from 7.0 (6.0, 8.0) at baseline to 4.0 (3.0, 5.0) at 1 month, remained at 4.0 (3.0, 5.0) at 3 months, and increased slightly to 5.0 (4.0, 5.0) at 6 months and 5.0 (4.0, 6.0) at 9 months, yet pain relief remained lower than baseline.

However, the management of postoperative pain caused by intercostal nerve injury, pleural irritation, and tissue retraction remains a major challenge. Despite the less invasive nature of MICS, patients often report experiencing pain similar to that experienced following conventional cardiac surgery, particularly during the acute postoperative period. Effective pain management is essential for optimizing recovery, reducing the consumption of opioids, and preventing the transition to chronic postsurgical pain. Regional anesthesia techniques play a key role in multimodal analgesia for MICS. Thoracic epidural analgesia exhibits strong analgesic efficacy; nevertheless, it remains underutilized owing to concerns regarding anticoagulation-related complications and hemodynamic instability. The thoracic paravertebral block is a safer alternative that provides comparable pain relief with fewer side effects. Similarly, ultrasound-guided fascial plane blocks, such as serratus anterior, parasternal intercostal, interpectoral + pectoserratus, and erector spinae plane blocks, have gained popularity owing to their safety and feasibility; however, the effectiveness of these blocks varies according to the surgical approach and type of incision. Systemic analgesia is an integral component of multimodal pain management in MICS. Despite the efficacy of opioids, a shift toward opioid-sparing strategies has been observed given the significant adverse effects associated with the use of opioids. Intravenous adjuncts such as dexmedetomidine, ketamine, and non-steroidal anti-inflammatory drugs can reduce opioid consumption and improve postoperative pain control. Despite advances in pain management, a single approach that can provide comprehensive analgesia for MICS remains to be established.

With chronic pain that is refractory to the aforementioned treatments, more invasive procedures may be indicated. Cooled radiofrequency ablation (CRFA), a minimally invasive therapy, utilizes internally cooled radiofrequency probes to deliver targeted thermal energy that causes neurolysis, disrupting the transmission of pain stimuli along nociceptive pathways, thus resulting in pain relief [Walker in J Spinal Disord 13:205-217, 2000 June].

Information regarding opioids, and route of administration, prescribed prior to admission, during admission, and at time of discharge was recorded. Opioids, doses, and routes were changed according to the clinical need to obtain the maximum benefit, individualizing the treatment. The opioid escalation index was calculated in milligrams (OEImg) and as a percentage (OEI%).</p><p><strong>Results: </strong>A total of 113 patients were assessed. The mean pain intensity at admission and at time of discharge was 6.4 (SD 1.8) and 2.3 (SD 1.4), respectively (P < 0.0005). The mean opioid dose expressed as oral morphine equivalent (OME) by patients who were receiving opioids before admission was 128 mg/day (SD 120). There was no statistical difference in OME between admission and discharge time. Sixty-one and 20 patients were prescribed a second and a third opioid/route, respectively. Mean OEI% and OEImg were 9.3% (SD = 22.5) and 4.0 mg/day (SD = 24.1), respectively. Only a minority of patients had a breakthrough pain prescription at admission. Intravenous morphine was more frequently prescribed at beginning, then replaced by oral morphine and fentanyl preparations at discharge.</p><p><strong>Conclusions: </strong>An intensive and careful use of opioids in the APCU allows for the achievement of adequate analgesia in all examined patients within a short time, without increasing OME. These findings should encourage further studies in APCUs as well as in other palliative care settings.</p>","PeriodicalId":19908,"journal":{"name":"Pain and Therapy","volume":" ","pages":"999-1006"},"PeriodicalIF":4.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12085417/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143743565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
