Brief summary
This study compared the cost effectiveness of two-stage algorithm (prolotherapy injections (PrT) combined with rehabilitation protocol (RP) prior to total knee arthroplasty (TKA)) and one-stage algorithm (TKA) in the management of advanced stage knee osteoarthritis.
Detailed description
The aim of the present study was to compare the cost effectiveness of two-stage algorithm (prolotherapy injections (PrT) combined with rehabilitation protocol (RP) prior to total knee arthroplasty (TKA)) and one-stage algorithm (TKA) in the management of advanced stage knee osteoarthritis. A total of 197 patients who had chronic knee osteoarthritis were included in the present study. The patients were divided into two groups as two-stage algorithm (PrT combined with RP prior to TKA), (Group A, n=98) and one-stage (TKA),(Group B, n=99). Clinical effectiveness was evaluated via Visual Analog Scale (VAS), The Western Ontario and McMaster Universities Arthritis Index (WOMAC) at baseline and 3-, 6-, 12-, and 18-month follow-ups. Utility scores of the groups were obtained by extracting and converting WOMAC scores to health utilities index mark 3 scores. Cost-utility per quality-adjusted life years (QALY) and Incremental cost-effectiveness ratios (ICERs) of each group were calculated.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Scale (VAS) | 18 months | Self reported pain intensity. Each item is scored 0-10 (0=no pain; 10= pain as bad as can be), yielding a total between 0 and 10. |
| The Western Ontario and McMaster Universities Arthritis Index (WOMAC) | 18 months | Self-administered questionnaire consisting of 24 items divided into 3 subscales: Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing upright Stiffness (2 items): after first waking and later in the day Physical Function (17 items): using stairs, rising from sitting, standing, bending, walking, getting in / out of a car, shopping, putting on / taking off socks, rising from bed, lying in bed, getting in / out of bath, sitting, getting on / off toilet, heavy domestic duties, light domestic duties. Each item is scored 0-96 (0=minimum; 96= as bad as can be), yielding a total between 0 and 96. |
