Introduction:
Medial-parapatellar-arthrotomy is the standard approach for total knee replacement(TKR). No studies have clarified the outcomes as quadriceps-strength-recovery (QS) and safety of Continuous-locking-suture-technique(CLS) for the arthrotomy-repair.
Methods:
Patients were randomly assigned into a CLS(n = 40) and an interrupted-horizontal-mattress(IHM, n = 40). QS, visual-analog-scale(VAS), modified-timed-up-and-go(TUGT) test, Western-Ontario-and McMasters-Universities-Osteoarthritis-Index[WOMAC] and Knee-Society-Score[KSS] were followed for 6 months'.
Results:
A significantly-shorter capsular-closure-time in CLS(233 ± 40 VS 388 ± 47 sec)(p < 0.0001). There were insignificant difference in QS, VAS, TUGT, WOMAC and KSS during the 6-month follow-up period(p > 0.05 all). No wound complications were found.
Conclusion:
CLS with braided-suture is safe and effective as demonstrated a recovery of the QS and knee function outcome comparable to IHM.
Trial Registration:
This study was registered in Thai Clinical Trials Registry on December 2015 (https://www.clinicaltrials.in.th). The registration number was TCTR20151208003.
