Comparison of the Efficacy of Ultra-congruent Prosthesis and Posterior-stabilized Prosthesis in Total Knee Arthroplasty
Objective To compare the short-term clinical efficacy of ultra-congruent(UC)prosthesis and posterior-stabilized(PS)prosthesis in patients with end-stage knee osteoarthritis undergoing primary knee arthroplasty(TKA).Methods The clinical data of 58 patients with end-stage knee osteoarthritis who underwent TKA for the first time in the Fourth People's Hospital of Guiyang City from January 2020 to January 2022 were retrospectively analyzed.The patients were divided into UC group(n=29)and PS group(n=29)according to the use of knee prosthesis.The operation time,intraoperative blood loss,postoperative hemoglobin(Hb)decrease,visual analogue scale(VAS),hospital for special surgery knee score(HSS),range of motion(ROM)and postoperative complications were compared between the two groups.Results The operation time of UC group was shorter than that of PS group,and the decrease of Hb was lower than that of PS group(P＜0.05),while there was no significant difference in intraoperative blood loss between the two groups(P＞0.05).The HSS score and knee joint ROM of the two groups at 3,6 and 12 months after operation were higher than those before operation(P＜0.05),while there was no significant difference between the two groups(P＞0.05).The VAS scores of the two groups at 3,6 and 12 months after operation were lower than those before operation(P＜0.05),while there was no significant difference between the two groups(P＞0.05).There were no prosthesis loosening,joint infection,joint instability and dislocation in the two groups.There were 8 cases of anterior knee pain in the PS group and 1 case of anterior knee pain in the UC group during the follow-up period,the difference between the two groups was statistically significant(P＜0.05).Conclusion The short-term efficacy of UC prosthesis and PS prosthesis in TKA surgery is similar,but UC prosthesis does not require intercondylar osteotomy to make intercondylar box,can retain more bone mass,and has less damage,less Hb decrease,shorter operation time,and less complications such as anterior knee pain,which is worthy of clinical use.
