Primary Outcome Measures:
  • Improvement in Knee Society Knee Score [ Time Frame: Initial(one day before surgery), and at 3 months, 1 year, then annually after surgery ]
    change in knee score will be compared with initial score, until mean follow up of 25 years.


Secondary Outcome Measures:
  • Improvement in the Range of Motion [ Time Frame: Initial(one day before surgery), and at 3 months, 1 year, then annually after surgery ]
    change in the range of motion of knee joint will be compared with the initial value, until mean follow up of 25 years.

Primary Completion Date: February 1998 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cementless Nexgen CR
Cementless fixation of Nexgen CR TKR
Device: Cementless (Nexgen)
Cementless fixation of Nexgen CR TKR
Other Name: Cementless Nexgen
Active Comparator: Cemented Nexgen CR
Cemented fixation of Nexgen CR TKR
Device: Cemented (Nexgen)
Cemented fixation of Nexgen CR TKR

Detailed Description:

Out comes measures were to determine:

  1. whether the knee and function scores and the radiographic results of the knees with a Nexgen cemented knee prosthesis would be better than those with an Nexgen cementless prosthesis.
  2. whether the patients with a Nexgen cemented knee prosthesis would have a better range of knee motion than those with an Nexgen cementless prosthesis.
  3. whether patient satisfaction and preference would be better in the patients having a Nexgen cemented knee prosthesis than those of patients having an Nexgen cementless knee prosthesis
  4. whether complication rate would be less in the knees with a Nexgen cemented knee prosthesis than in the knees with an Nexgen cementless prosthesis.
