Impact Of Early Bed Mobility On The Prognosis Of Knee Arthroplasty

OBJECTIVE: To investigate the effect of early postoperative bed activity on the prognosis of patients undergoing total knee replacement.METHODS: From June 2019.06 to 2010.07,40 patients who underwent unilateraltotal knee arthroplasty were included,40 knees in total(n=40),of which22 were female(n=22)and 18 were male(n=18),and the included patientswere randomly divided into experimental group(n=20)and control group(n=20).The control group was treated with conventional rehabilitationafter knee arthroplasty,while the experimental group underwent earlypostoperative bed activity training on the basis of conventionalrehabilitation after knee arthroplasty.Knee function,pain level and self-care ability of daily life were assessed at 1 week,2 weeks,3 weeks and 4 weeks after surgery to compare the differences in knee function,postoperative pain level and self-care ability between the experimentalgroup and the control group,and to explore the impact of earlypost-operative bed activity on the prognosis of patients with total kneereplacement.RESULTS:1.The AKS score and ADL score of the knee joint at 1week,2 weeks,3 weeks and 4 weeks after surgery in the experimental group were higherthan those in the control group(P<0.05);the absolute time of bed restafter surgery was significantly shorter than that in the control group(P<0.05),suggesting that early bed activity after surgery can improve thefunction of the knee joint after surgery,improve the patients’ abilityto take care of themselves in daily life and shorten the absolute time ofbed rest after surgery.2.The VAS pain scores of the experimental groupat 1week and 2 weeks after surgery were not significantly different fromthose of the control group(P>0.05),and the VAS pain scores at 3 weeksand 4weeks after surgery were lower than those of the control group(P<0.05),suggesting that our early postoperative bed activity did not aggravate thepostoperative pain level of the patients and had a positive effect onreducing long-term postoperative pain.In conclusion: early postoperativebed activity in patients with total knee arthroplasty can facilitate therecovery of knee function,shorten the absolute postoperative bed rest time,reduce the level of postoperative pain,and help patients achieve betterself-care ability.
