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: Pseudoaneurysm is a rare complication of surgery of the knee. The pathogenesis of false aneurysm involves partial arterial laceration, which allows hemorrhage into surrounding soft tissues that confine it. Although most cases in literature described pseudoaneurysms after total knee arthroplasty, it can be associated with arthroscopic knee surgery too. METHODS: Here, we report an uncommon case of a false aneurysm of the superior lateral genicular artery following anterior cruciate ligament ligamentoplasty using an autograft semitendinosus-tendon...

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...

BACKGROUND: The lateral femoral condyle (LFC) flap is a vascularized bone flap based on the superior lateral genicular artery (SLGA). Harvest technique for this flap has not yet been demonstrated. The purpose of this study was to better delineate the blood supply to the bone and skin of this flap to allow for a safe and effective harvest. MATERIALS AND METHODS: Twenty-three lower extremities were injected with latex or a mixture of latex and barium sulfate. The SLGA was identified and dissected, documenting the course, diameter, anatomical relations, length, and branches...

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.

INTRODUCTION: Symptomatic knee osteoarthritis (OA) is common. Advanced knee OA is successfully treated with joint replacement surgery, but effectively managing mild to moderate knee OA can be difficult. Angiogenesis increases with OA and might contribute to pain and structural damage. Modifying angiogenesis is a potential treatment pathway for OA. The aim of the current study is to determine whether transcatheter arterial embolisation of abnormal neovasculature arising from the genicular arterial branches improves knee pain, physical function and quality of life in people with mild to moderate symptomatic knee OA...

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...

Ferdinand Iannaccone, Samuel Dixon, Andrew Kaufman
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...

PURPOSE: Despite being the largest ligament on the posterior aspect of the knee, relatively little is known about the normal morphology of the oblique popliteal ligament (OPL). The aim of this study was to investigate the detailed anatomy of the OPL in cadavers and healthy volunteers. METHODS: The posterior knee was investigated in 25 cadaver lower limbs (mean age 76 ± 9.5 years; 7 men) by dissection, histology, and serial plastination and in 14 healthy individuals (mean age 23 ± 3...

BACKGROUND: Nonunion involving the metaphyseal region of the distal radius is exceedingly rare, usually involving co-morbidity. Patients that have failed multiple prior conventional surgical interventions represent an even more difficult subset to treat; this investigation examined the utility of a specially designed free vascularized medial femoral condyle flap consisting of a central structural block graft with an extended corticoperiosteal sleeve to wrap around the junctions. METHODS: Six patients (5 males, 1 female) with a mean age of 52 years had failed to achieve union involving the distal radius metaphysis after a mean of 3...
