Abstract:Objective To explore the early effect of early rehabilitation based on enhanced recovery after surgery (ERAS) concept in patients with medial compartment knee osteoarthritis after high tibial osteotomy(HTO). Methods Out of 59 patients with medial compartment knee osteoarthritis undergoing HTO from June 2018 to July 2019,30 patients were enrolled in control group receiving conventional nursing intervention,and 29 patients were selected in observation group receiving conventional nursing combined with early rehabilitation based on ERAS concept ［including physical factor therapy,cold compress,manual lymphatic drainage,muscle strength training,joint loosening,continuous passive motion(CPM) training］.Before and two weeks after intervention,visual analogue scale (VAS),knee joint range of motion (ROM,including knee flexion and extension range of motion),knee function score ［American Hospital for Special Surgery (HSS)］ and the differences of limb circumference and skin temperature between the affected limb and the healthy limb were measured and compared between two groups. Results Before intervention,there were no significant differences in observation indexes between two groups (P>0.05).After intervention,ROM,VAS,HSS and the differences in limb circumference and skin temperature between the affected limb and the heatlhy limb were significantly improved in observation group and were superior to those in control group (P<0.01).In control group,the above-mentioned indicators were significantly improved (P<0.05,P<0.01),except for the knee joint extension range of motion (P>0.05). Conclusion For the patients with medial compartment knee osteoarthritis,early rehabilitation based on ERAS concept can effectively improve joint range of motion,reduce pain and swelling of limbs,lower skin temperature,and promote the recovery of joint function after HTO.
