Clinical outcomes and patient satisfaction of fixed-bearing unicompartmental knee arthroplasty revision for dislocation of mobile-bearing unicompartmental knee arthroplasty liner
摘要
Abstract
Objective To evaluate the clinical outcomes and patient satisfaction of patients who underwent revision surgery with fixed-bearing unicompartmental knee arthroplasty(FB-UKA)for mobile-bearing unicompartmental knee arthroplasty(MB-UKA)liner dislocation,and to compare these outcomes with those of patients who received primary FB-UKA.Methods A retrospective analysis was performed on the clinical data of 12 patients who underwent revision surgery with FB-UKA for liner dislocation after MB-UKA at the department of Orthopedics,Suzhou Municipal Hospital,from June 2017 to December 2023,and these patients were enrolled as the revision group.A 1:2 propensity score matching was conducted to pair these patients with 24 contemporaneous patients who received primary FB-UKA for medial compartment knee osteoarthritis,with matching criteria including gender,age,body mass index(BMI),age-adjusted Charlson comorbidity index(ACCI).These 24 patients were enrolled as the primary group.The two groups were compared in terms of operative time,total perioperative blood loss,postoperative length of hospital stay,and early postoperative complications.Additionally,comparisons were made regarding postoperative patient-reported outcome measures(PROMs),including the visual analogue scale(VAS)for pain,knee range of motion(ROM),Knee Society Score(KSS),Oxford Knee Score(OKS),Short Form 36 Health Survey(SF-36),as well as patients'surgical expectations and overall satisfaction.Results All patients completed follow-up,with a mean follow-up time of(26.45±2.32)months(24-36 months).Compared with the primary group,the revision group had significantly longer operative time,greater total perioperative blood loss,and longer postoperative length of hospital stay(P<0.05).At 1st and 3rd weeks postoperatively,the revision group had higher VAS scores and lower knee ROM than the primary group,with statistically significant differences(P<0.05).There were no statistically significant differences in VAS scores and knee ROM between the two groups at 1st and 3rd months postoperatively(P>0.05).No significant differences were observed in early postoperative complications and prosthesis-related complications during the follow-up period between the two groups(P>0.05).During the 2-year follow-up,there were no significant differences in postoperative PROMs and patient satisfaction between the two groups(P>0.05).Conclusion PROMs of patients undergoing revision surgery with FB-UKA for MB-UKA liner dislocation were significantly improved compared with those before surgery.Moreover,the clinical outcomes and patient satisfaction after revision from MB-UKA liner dislocation to FB-UKA were comparable to those after primary FB-UKA.关键词
