A randomized blinded study is conducted comparing 2 different knee prostheses. Range of motion (ROM), pain, feel of prosthesis, satisfaction and ability to do daily activities are registered at intervals up to one year postop, where patients are informed on which prosthesis they received.

We want to:

  • determine whether an increased ROM is achieved with a high-flex knee compared to a standard knee
  • and if so, does it matter

Condition Intervention Phase
Osteoarthritis, Knee

Primary Outcome Measures:
  • ROM
  • Pain
  • Satisfaction
  • Feel of prosthesis
  • Gait analysis

Estimated Enrollment: 100
Study Start Date: January 2004
Estimated Study Completion Date: January 2010
Detailed Description:

100 patients operated on with unilateral TKR are included and randomized to either prostheses.

Patients operated on with bilateral simultaneous TKR receive one of each prostheses but are blinded to which prosthesis is on which side. They have gait analyses performed preop and at intervals up to one year.
