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...

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...

Genicular nerve radiofrequency ablation (RFA) has recently gained popularity as an intervention for chronic knee pain in patients who have failed other conservative or surgical treatments. Long-term efficacy and adverse events are still largely unknown. Under fluoroscopic guidance, thermal RFA targets the lateral superior, medial superior, and medial inferior genicular nerves, which run in close proximity to the genicular arteries that play a crucial role in supplying the distal femur, knee joint, meniscus, and patella...

BACKGROUND: The lateral retinacular nerve (LRN) is a branch of the superior lateral genicular nerve (SLGN) and is believed to contribute to anterolateral knee pain. The precise anatomical pathway of the LRN, however, has not been demonstrated as it relates to the performance of targeted nerve block procedures. OBJECTIVE: To describe the anatomical landmarks for localization of the LRN to facilitate diagnostic and therapeutic nerve blocks in the treatment of chronic anterolateral knee pain...

BACKGROUND AND OBJECTIVES: Adductor canal block contributes to analgesia after total knee arthroplasty. However, controversy exists regarding the target nerves and the ideal site of local anesthetic administration. The aim of this cadaveric study was to identify the trajectory of all nerves that course in the adductor canal from their origin to their termination and describe their relative contributions to the innervation of the knee joint. METHODS: After research ethics board approval, 20 cadaveric lower limbs were examined using standard dissection technique...

BACKGROUND: Heterotopic ossification (HO) is the ectopic bone formation in non-osseous tissues. This study aimed to present two patients with traumatic brain injury (TBI) who had HO in knee joint and pain relief after genicular nerve blockage. Case 1: A 14-year-old patient with TBI was admitted with bilateral knee pain and limited range of motion. Physical examination and x-ray graphics revealed calcification which was diagnosed as HO. Ultrasonography (US) guided genicular nerve blockage was performed to both knees with 2 ml lidocaine and 1 ml betamethasone...

BACKGROUND: Knee osteoarthritis is a frequent cause of chronic knee pain. Therapeutic solutions include intra-articular injections with short-term pain relief and surgical therapy. Radiofrequency (RF) of genicular nerves has been previously reported with varying success. Cooling tissue adjacent to the electrode (cooled RF) increases the radius of lesion. We present here the first retrospective data on pain relief and changes in function after such cooled RF denervation. METHODS: We reviewed the records of nine patients with chronic knee pain who underwent cooled RF of genicular nerves...

Recently, investigators began using radiofrequency to manage knee osteoarthritis pain in patients at high risk who cannot undergo surgical intervention. To our knowledge, no study has investigated the use of radiofrequency ablation of the genicular nerves to alleviate chronic knee pain after total knee replacement. A single case is presented here in which genicular nerve ablation successfully improved pain and restored function. We believe that these preliminary results could be used in the development of future prospective cohort studies and randomized controlled trials that focus on the use of radiofrequency ablation to treat persistent knee pain after total knee replacement...

Cystic adventitial disease (CAD) is a rare condition in which cyst is found within a vessel, typically producing symptoms of vascular compromise. Most commonly located in the popliteal artery near the knee, it has been reported in arteries and veins throughout the body. Its pathogenesis has been poorly understood and various surgical approaches have been recommended. We extrapolated some recent information about a similar condition, intraneural ganglion cyst affecting the deep fibular (peroneal) nerve, to the prototype, CAD of the popliteal artery...

PURPOSE: To investigate the feasibility and safety of a less invasive surgical approach to the distal medial aspect of the femur in supracondylar medial closing wedge osteotomy for the treatment of lateral compartment osteoarthritis of the knee. The aim of a less invasive approach is to minimize soft tissue disruption, reduce damage to neurovascular structures and thereby prevent muscle atrophy and optimize bone healing potential. METHODS: A human cadaver dissection study on the vascular and neural structures of the medial side of the distal femur was conducted...
