Effects of Short Wave Diathermy Added on Dextrose Prolotherapy Injections in Osteoarthritis of the Knee

SWD group took short wave diathermy with specifications of 400 watt power output, 27.12 MHz frequency, 11.06m wave length, using condensators and electrodes of 12 cm diameter parallel to the knee for 20 minutes(Enraf-Nonius, Curapuls 970 Short wave diathermy device).

Prolotherapy solutions were injected to the knee by a blinded physician in the group, using 25 gauge needle, with solutions being 6 ml 25 % dextrose (3 ml 20% dextrose + 3 ml 30% dextrose) for intraarticular, and 20 ml 15% dextrose (10 ml 0,9% NaCl + 10 ml 30% dextrose) for periarticular. Injection points wwere defined as medial collateral ligaments, adhesion points of quadriceps tendon, adhesion points of patellar tendon, tuberositas tibia, pes anserinus, lateral collateral ligaments, coronal ligaments, medial and lateral tibia plateaus. Patients were blinded to their treatment groups
