Pain was measured daily using VAS scale which consisted of markings from 1 to 10. Number of tramadol injections given was also noted. Hemoglobin was measured on the day of surgery and postop day 3 by sysmex automated analyser. Postoperative blood loss was also noted by measuring the weight of soaked dressing and converting it into blood volume. Number of blood units transfused was also recorded. Post operative wound dressing was done on day 3 except in case of soakage. Wound was assessed using wound score form. Similar physiotherapy was advised for both the groups. All the patients were advised isometric quadriceps and ankle pumping exercises on postoperative day 0 (POD0). Patients with less pain did the exercises on POD0 only. They were advocated range of motion exercises and straight leg raising on POD1. Patients with decreased pain and who were comfortable were ambulated with help of a walker on POD2. Range of motion was recorded on day 5, 6 weeks and 12 weeks and 6 months postoperatively. WOMAC scores and KSS scores were noted as shown in outcome evaluation.
