title: No difference between double-high insert and medial-pivot insert in TKA.
abstract: OBJECTIVE
  To compare the clinical midterm results in ADVANCE total knee arthroplasty (TKA) with double-high (DH) insert, with same type implant with medial-pivot (MP) insert.
  
  
  METHODS
  Forty ADVANCE TKAs were randomly divided into two groups, and two different design insert, DH insert, and MP insert were used in each group. At midterm, 4-5 years after surgery, Knee Society Scores (KSS), Knee Society Functional Scores (KSFS), range of motion (ROM), and UCLA activity score were assessed and reported in this study.
  
  
  RESULTS
  Midterm clinical results, including ROM and KSS, were comparable with both groups. KSFS and UCLA activity score were equally good between the two groups.
  
  
  CONCLUSIONS
  The results in this study revealed equally good clinical results with these types of implants at midterm follow-up, although the significant better ROM has not achieved by using DH insert. We concluded that the selection of inserts only could not achieve the better clinical results, including ROM and activity level in this study.
  
  
  METHODS
  Therapeutic studies-investigating the results of treatment, Level II.
