Table 8 Absolute MCID after total knee replacementd

From: Patient-reported health outcomes after total hip and knee surgery in a Dutch University Hospital Setting: results of twenty years clinical registry

  T = 6 months T = 12 months
WOMACa 75.8% (N = 178) 80.2% (N = 177)
KSS function scoreb 58.7% (N = 213) 62.6% (N = 219)
VAS painc 83.3% (N = 204) 85.6% (N = 201)
  1. aSeveral criteria exist for estimating clinically important improvements in using the WOMAC. We used a pragmatically chosen cut-off point of at least 20 points improvement
  2. bKSS scores have been categorized in >80 excellent; 70–79 good; 60–69 fair and <60 bad [36]. We defined a clinically relevant improvement as one category improvement
  3. cWe used a difference of 20 mm or more as clinically relevant improvement [34]
  4. dWOMAC: 3.1% were excluded because of ceiling. KSS function score: 4.6% were excluded because of ceiling. VAS pain: 5.4% were excluded because of ceiling
