Interventions
OTHERWeight gain
≥5% weight gain
OTHERWeight loss
≥5% weight loss after arthroplasty
OTHERWeight unchanged
\<5% weight change after arthroplasty

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Moderate/Severe Persistent Postoperative Pain | 11-15 months postsurgically | The primary outcome is the number of patients with moderate or severe persistent postsurgical pain in the operated hip or knee, defined as patients with a numerical rating scale (NRS) score higher than 3. The outcome will be presented as Odd Ratio (OR) with its' corresponding 95% Confidence Interval (CI) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Willingness to repeat the surgery | 11-15 months postsurgically | Answering yes in willlingness question The outcome will be presented as Odd Ratio (OR) with its' corresponding 95% Confidence Interval (CI) |
| Frequent pain | 11-15 months postsurgically | Experiencing pain constantly, daily or few times a week The outcome will be presented as Odd Ratio (OR) with its' corresponding 95% Confidence Interval (CI) |
| Satisfaction | 11-15 months postsurgically | Answering with satisfied or very satisfied in satisfaction question The outcome will be presented as Odd Ratio (OR) with its' corresponding 95% Confidence Interval (CI) |
| Interference with daily activities | 11-15 months postsurgically | Answering some, much and very much in the interference question The outcome will be presented as Odd Ratio (OR) with its' corresponding 95% Confidence Interval (CI) |
| WOMAC pain score | 11-15 months postsurgically | mean (standard deviaiton \[SD\]). We will report the mean difference (MD) and the corresponding 95% CI |
| Use of analgaesic | 11-15 months postsurgically | The outcome will be presented as Odd Ratio (OR) with its' corresponding 95% Confidence Interval (CI) |
