Mean scores for each section of quality of life before and one year after surgery (n = 264); data are mean ± standard error of the mean. For quality of life dimensions, see footnote in Table 2 for complete labels. Comparison of the scores before and one year after the operation demonstrates an improvement in quality of life in all but three dimensions of the SF36 scales. **p < 0.001; *p < Open bars = preoperative; shaded bars = postoperative. (MCS = mental component summary scores; PCS = physical component summary scores).

Patient classification according to the two main quality of life dimensions illustrated by multivariate analysis: physical functioning and pain. In group 1 the positive predictive value for the 1-year “satisfactory” status was 88%; it was 75% in group 2 and 50% in group 3.
