Randomized Controlled Trial
A Prospective Randomized Comparison of the Efficacy of Ultrasound- vs Fluoroscopy-Guided Genicular Nerve Block for Chronic Knee Osteoarthritis.
Recently, genicular nerve block and radiofrequency ablation were introduced to alleviate knee pain in patients with chronic knee osteoarthritis. Both ultrasound- and fluoroscopy-guided genicular nerve blocks have been used. However, whether one is superior to the other remains unknown. ⋯ Genicular nerve block, ultrasound, fluoroscopy, knee osteoarthritis, Numeric Rating Scale, The Western Ontario and McMaster Universities Osteoarthritis Index.

Radiofrequency Thermoablation of the Gasserian Ganglion Versus the Peripheral Branches of the Trigeminal Nerve for Treatment of Trigeminal Neuralgia: A Randomized, Control Trial.
Trigeminal neuralgia is the most painful condition of facial pain leading to impairment of routine activities. Although radiofrequency thermoablation (RFT) of the Gasserian ganglion is widely used for the treatment of idiopathic trigeminal neuralgia in patients having ineffective pain relief with medical therapy, the incidence of complications like hypoesthesia, neuroparalytic keratitis, and masticatory muscles weakness is high. Recent case reports have shown the effectiveness of RFT of the peripheral branches of the trigeminal nerve for relief of refractory chronic facial pain conditions including trigeminal neuralgia. ⋯ Idiopathic trigeminal neuralgia, radiofrequency thermoablation, Gasserian ganglion, peripheral nerve branches, pain, trigeminal nerve.

The facet joints contribute to chronic cervical spine pain in an estimated 55% of chronic neck pain cases and can be treated with percutaneous radiofrequency neurotomy (PRN). Damage to surrounding structures during treatment or successful treatment of the primary pain source leading to unmasking could lead to new onset of pain, including cervicogenic headache (CGH). In this study, we aimed to define the incidence of headache in patients who have been previously treated with PRN for lower cervical facet pain. ⋯ Cervical spine, facetogenic pain, percutaneous radiofrequency neurotomy, cervicogenic headache, chronic pain, zygapophysial joints, innervation convergence, retrospective chart review.

Controversy is not uncommon in the diagnosis of discogenic low back pain (DLBP) and in the identification of the location of the pain source for the symptomatic disc in patients with DLBP. Various techniques, from minimally invasive procedures to fusion surgery, are used to treat chronic DLBP, but the clinical outcomes are variable. Percutaneous endoscopic discectomy by transforaminal or interlaminar approach is considered to be an effective method to treat DLBP, but the evidence is limited; the lack of clear evidence may be associated with patient selection and surgical technique. ⋯ Transforaminal, interlaminar, outside-in technique, endoscopic discectomy, discogenic low back pain.

Acute postoperative pain is an independent predictor of chronic postsurgical pain following total knee arthroplasty at 6 months: a prospective cohort study.
Approximately 15% of patients report persistent knee pain despite surgical success following total knee arthroplasty (TKA). The purpose of this study was to determine the association of acute-postsurgical pain (APSP) with chronic postsurgical pain (CPSP) 6 months after TKA controlling for patient, surgical and psychological confounding factors. ⋯ APSP is a risk factor for CPSP following TKA even after adjusting for confounding variables such as pain catastrophizing, anxiety, depression and functional status. Studies are needed to determine if APSP is a modifiable risk factor for the development of CPSP.
