The nerve block of the articular branch of the tibial nerve was carried out with 1ml of 1% Lidocaine in 68 knee joints with severe pain mostly in the distal antero-medial portion.
Although the pain was disappeared in 23 and was reduced markedly in 37 after blockage, the effect was continued for only one hour in a majority of the cases. The neurectomy or the nerve block with 1ml of absolute alcohol or 10% phenol solution was carried out in 8 and 9 respectively to get a continuous reduction of pain. The result was satisfactory in the neurectomy but less effective in the nerve block.
