Objective To compare and analyze the effectiveness of unicompartmental knee arthroplasty(UKA) and total knee arthroplasty(TKA) in the treatment of osteoarthritis of the knee in the medial compartment.Methods A retrospective analysis was conducted on 78 patients with the knee osteoarthritis(KOA) in the medial compartment who were admitted to the First Affiliated Hospital of Xinxiang Medical College from January 2019 to September 2021.The patients were divided into the UKA and TKA groups according to the surgical method.There were 39 patients in the UKA group,including 7 males and 32 females.The patients’age ranged from 45 to 74 years,with an average of (63.4±7.9)years.And the body mass index(BMI) was (25.92±2.70)kg/m2.There were 39 patients in the TKA group,including 12 males and 27 females.The patients’age ranged from 53 to 76 years,with an average age of (65.8±6.3)years,and the BMI was (26.61±4.07)kg/m2.The surgical time,intraoperative blood loss,total hospital stay,postoperative drainage volume,visual analogue scale(VAS) pain score,range of motion(ROM) of the knee joint,the hospital for special surgery(HSS) knee score,and the forgotten joint scores(FJS) were compared between the two groups.Results The follow-up time was 12 to 16 months,with a mean of (14.1±1.1)months.The UKA group had significantly less surgical time,total hospital stay,surgical incision length,intraoperative blood loss,and postoperative drainage volume than the TKA group (P<0.05).There was no statistically significant difference in preoperative VAS,ROM,and HSSs between the two groups(P>0.05).However,the postoperative 3,6 and 12 months VAS,HSS,and ROM scores of the UKA group were superior to those of the TKA group (P<0.05).The postoperative 3,6,and 12 months FJS scores of the UKA group were also higher than those of the TKA group,with statistical significance (P<0.05).Conclusion Both UKA and TKA can significantly relieve knee joint pain and improve knee joint function in the treatment of medial compartment KOA.Compared with TKA,UKA has the advantages of being less invasive,faster recovery,and less noticeable sensation of the prosthesis after surgery.
