Plantar fasciitis remains one of the leading causes of long term disability. Many studies have been conducted on management of pain and improvement in foot function. Therapy in the form of rest, stretching, analgesic agents, physical therapy, arch support, night splints, shoe modifications or steroid injections are the conservative treatments available. Extracorporeal shock wave therapy (ESWT), radiofrequency nerve ablation (RFNA) and platelet rich plasma (PRP) are other options that can be considered for recalcitrant plantar fasciitis. At present there are very limited literature regarding RFNA of medial calcaneal nerve for the treatment of recalcitrant plantar fasciitis. Therefore, the aim of the study is to determine the effectiveness of ultrasound guided radiofrequency nerve ablation in the management of plantar fasciitis. A sample size of 39 patients in each group who are willing to take part in the study will be taken from those plantar fasciitis patients who are attending the OPD of PMR department, RIMS. Outcomes will be measured by using , visual analogue scale ( VAS), ultrasound measurement of plantar fascia thickness and American Orthopedic Foot and Ankle Society (AOFAS) ankle hind-foot score at one, four, twelve and twenty-four weeks post- intervention. Study design will be randomized controlled trial.
