Further study details as provided by Ivan Brenkel, NHS Fife:

Primary Outcome Measures:
  • Predictors of poor outcomes using 3 measures [ Time Frame: 10 years ]
    A prospective database was set up in October 1998. Patient details were collected preoperatively, intra operatively and immediately post operatively. Patients are then followed up in a dedicated knee clinic at 6 months, 18 months, 3 years and 5 years. Data such as SF12 and the American Knee Society Score was done at each visit

Study Start Date: October 1998
Study Completion Date: October 2008
Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
Detailed Description:
It is known that surgical outcomes are good in the majority following a Sigma knee at 5 years. 3% have persistent pain. Is it possible to predict these patients? Is it possible to make a determination as to which of the 3 outcome measures ((1) American Knee Society Score; (2) SF12 Oxford 12 and (3) Complications) is most appropriate to use and when is the most appropriate time to use it
