INTRODUCTION: The goals for the management of patients with osteoarthritis (OA) of the knee are to control pain and to minimise disability. Because the number of patients will increase as the population ages, alternative approaches to alleviate their joint pain other than conventional treatments are necessary. The purpose of this article is to present a refined protocol to determine if there is long-term improvement in pain and function after ultrasound-guided pulsed radiofrequency treatment of the genicular nerves (GNs) in patients with chronic painful knee OA...

BACKGROUND: Chronic knee pain from osteoarthritis (OA) is common in the aging and the obese population. Radiofrequency ablation of the genicular nerves has been introduced as a potential surgery-sparing treatment for chronic knee pain from OA, yet only two outcome studies have been published and optimal patient selection for this procedure has not been established. OBJECTIVES: We describe a standardized protocol for selecting patients for cooled radiofrequency ablation (C-RFA) of the genicular nerves, as well as the clinical outcomes of four patients ages 63-65 years...

We report the case of a 71-year-old man complaining of swollen left limb and progressively worsening pain. He underwent surgery 12 years ago for popliteal artery aneurysm with proximal and distal ligation and venous bypass grafting. The patient was diagnosed as having left peroneal neuropathy caused by a 10.5 cm expanded aneurysmal sac compressing the peroneal nerve in the popliteal fossa. The patient underwent open repair with opening of the aneurysmal sac, removal of the thrombus, and sewing of the left genicular artery responsible for back-bleeding...

BACKGROUND AND OBJECTIVES: The popliteal nerve plexus contributes to afferent knee-pain conduction. It is mainly formed by genicular branches from the posterior obturator and the tibial nerves, innervating the intra-articular and posterior knee region. A subinguinal obturator nerve block alleviates pain after total knee arthroplasty. Reduced hip adductor motor function could be avoided by a posterior obturator nerve block inside the popliteal fossa.The aim of this study was to evaluate the spread of dye after a distal adductor canal (AC) injection to the popliteal fossa and coloring of the popliteal plexus and the genicular branch of the posterior obturator nerve by dissection...

We present a case of a 68-year-old woman with 6 months of chronic unilateral posterior thigh pain after a total knee arthroplasty. The patient's pain was refractory to various treatments. After appropriate diagnostic tests, a genicular nerve block and subsequent radiofrequency ablation were performed. These procedures provided substantial pain relief of her thigh pain at 3 months follow-up.

The objective is to increase awareness of facial nerve schwannomas (FNSs). Clinical data from 32 cases with FNSs who received surgical treatment from 2005 to 2015 were reviewed retrospectively. The clinical data included age, sex, presentations, duration, facial nerve function, temporal-bone high-resolution computed tomography (CT) and magnetic resonance imaging (MRI) findings, surgical approaches, and postoperative histopathological examination. 16 men and 16 women were included, aged 7-69 years. The average age at diagnosis was approximately 44 years...

INTRODUCTION: Total knee arthroplasty (TKA) is an operation with moderate to severe postoperative pain. The Fast-Track models employ local infiltration techniques with anaesthetics at high volumes (100-150ml). We proposed a genicular nerve block with low volume of local anaesthetic. The aim of our study is to evaluate the periarticular distribution of these blocks in a fresh cadaver model and to describe the technique in a preliminary group of patients submitted to TKA. MATERIALS AND METHODS: In the anatomical phase, 4 genicular nerves (superior medial, superior lateral, inferior medial and inferior lateral) were blocked with 4ml of local anaesthetic with iodinated contrast and methylene blue in each (16ml in total)...

The precise description of the fascia vasto-adductoria (FVA) has become an issue of great surgical and clinical importance. Neurovascular entrapment within the adductor canal (AC) may simulate many clinical conditions for cases presented with medial knee or leg pain and ischemic manifestations of the leg. The aim of the present work is to describe the morphological features of the FVA and to elucidate its neurovascular relations. Forty thigh specimens, pertaining to 15 embalmed and five fresh adult human cadavers, were dissected in pursuit of this aim...

BACKGROUND: Studies of radiofrequency ablation (RFA) of genicular nerves have reportedly significantly decreased pain up to 3 months post ablation, but no longer term effects have been reported. We performed an analysis of long-term pain relief of 31 RFA procedures of the genicular nerves to analyze the degree of pain relief past 3 months, culminating at 6 months. STUDY DESIGN: Chart review and study design was approved by Newark Health Sciences Institutional Review Board (IRB)...

BACKGROUND: Patients suffering from osteoarthritis of the knee and patients post total knee arthroplasty often develop refractory, disabling chronic knee pain. Radiofrequency ablation, including conventional, pulsed, and cooled, has recently become more accepted as an interventional technique to manage chronic knee pain in patients who have failed conservative treatment or who are not suitable candidates for surgical treatment. OBJECTIVE: This systematic review aimed to analyze published studies on radiofrequency ablation to provide an overview of the current knowledge regarding variations in procedures, nerve targets, adverse events, and temporal extent of clinical benefit...

BACKGROUND AND OBJECTIVES: Osteoarthrosis is a main cause of knee pain in the elderly. Pain associated with this condition is often refractory to conservative treatment. Total knee replacement may be the best option for severe pathologies; however, the occurrence of a chronic pain state after knee replacement has been well documented in the literature. The previous descriptions of the genicular nerves have been considered somewhat inaccurate. This innervation is complex and exhibits significant interindividual variability...

BACKGROUND AND OBJECTIVES: Radiofrequency ablation of genicular nerves has proved to be successful in relieving pain and incapacity caused by osteoarthritis of the knee. However, long-term efficacy of such a treatment remains to be assessed. The current study aimed to reproduce radiofrequency neurotomy of genicular nerves to manage gonarthrosis pain and disability and establish therapeutic response until 1 year after intervention. METHODS: This single-center, prospective, observational, noncontrolled, longitudinal study included patients with grade 3 to 4 gonarthrosis suffering from intractable knee pain, scoring 5 or more on the visual analog scale (VAS) during >6 months...

Osteoarthritis (OA) of the knee is one of the most common joint diseases affecting adults in the United States. For elderly patients with multiple medical comorbidities who do not wish to undergo total knee arthroplasty (TKA), lifestyle modification, pharmacologic management, and injections are the mainstay of therapy. Previously, pain management interventions were limited to intra-articular joint injections and viscosupplementation with hyaluronic acid. Fluoroscopic-guided techniques for radiofrequency ablation (RFA) of the genicular nerves have been previously described and a recent cadaveric study suggests that ultrasound-guided genicular nerve blocks can be performed accurately...

OBJECTIVES: To determine the location of distal medial neurovascular structures, identifying a medial "safe zone" for minimally invasive plate osteosynthesis to treat displaced femoral condylar fractures. METHODS: Eleven uninjured lower-half torsos were dissected on the bilateral medial lower thigh. A longitudinal incision was made at the midsagittal plane of the medial thigh starting 1 cm proximal to the knee joint and extending to the proximal one-third of the femur...

BACKGROUND: Knee osteoarthritis is a disease that affects a third of the population over 65 years of age, and it is increasingly becoming a motive for consultation and a source of pain and disability. The gold standard surgical treatment is a total knee arthroplasty; however, 15% to 30% of patients who have undergone surgery continue to experience pain and functional limitation. METHODS: A double-blind, randomized clinical study compared neurolysis using traditional radiofrequency (RF) to local anesthetic and corticosteroid block of the superolateral, superomedial, and inferomedial branches of the knee genicular nerves in patients who had total knee arthroplasty but still experience pain...
