Osteoarthritis (OA) is one of the most common degenerative disorders among the elderly population. Around 23.46 million individuals in India had OA in 1990; this increased to 62.35 million in 2019. DALY (Disability Adjusted Life Years) due to OA increased from 0.79 million to 2.12 million. OA was the 20th most common cause of YLDs ( Years Lived in Disability) in India in 2019, accounting for 1.48%  of all YLDs; increasing from 23rd most common cause in 1990 . Knee OA was the most common form of OA, followed by hand OA. The prevalence, incidence, and DALYs for OA and knee OA were consistently higher in females than male [1].

The current treatment of OA knee consists of conservative management such as exercise, physical therapy, pharmacological agents such as NSAIDS. Intake of analgesics to alleviate pain will cause renal damage, gastritis, peptic ulcers etc. When the conservative management fails to relieve pain, non surgical procedures like Intra Articular Injection of Cortico Steroids[2], Hyaluronic Acid [3][4], Platelet Rich Plasma [5] is widely used.The definitive treatment for OA knee is total Knee replacement surgery.

Intra Articular CorticoSteroids is one of the most commonly used minimally invasive OPD ( Out Patient Department) procedure where a corticosteroid drug is injected into intra articular space to alleviate pain. IACS decreases joint inflammation there by decreasing the pain for a short duration ( wks to months). 

         The radio frequency ablation is a new treatment methadology for chronic degenerative knee pain. The goal of cooled radio frequency ablation (CRFA) of genicular nerve is to alleviate the knee pain and improve the function and the quality of life of patients with OA knee. It is also a OPD procedure , done without any incision, recovery time is short and the patient can get back soon to their normal day to day activities. Under ultrasound guidance, RF needles will be inserted near the targeted nerves and a gentle electric current  ( cooled)  is passed through it to ablate the nerve. Cooled RFA is better than conventional RFA, as it targets a wider region and chance of ablating the nerve is high. As per previously published articles, the pain relief after RFA procedure may last for 6 month to 1 years duration. Nerves start to regenerate after 6 months and the procedure will provide control over pain long enough for rehabilitation.

Both the procedures are well tolerated in office setting under local anaesthesia or done in operating room under conscious sedation using a low dose sedative such as midazolam for anxious patients.
