Mesa: what to note before a joint exam

What to write down this week

Keep the note short enough to use each day. Mark the sore place and the first painful motion. Note whether rest helps or causes stiffness. Write down morning, afternoon, or bedtime. Add swelling, weakness, or a sudden loss of movement. Don't rate the whole day with one word. Record the task that became harder instead. Circle anything that changed since the last doctor visit. These facts can save time during a short exam.

A few exact words beat a long memory test.

What to bring for the exam

Take the medicine list and old scan reports. Bring the soreness note beside them. Wear loose clothing around the painful area. Point to the sore spot with one finger. Show the painful reach or step only when safe. Mention any fall, pop, or quick change. The examiner may move the joint and press tender areas. Strength and swelling may also be checked. That work helps explain which daily motions need care.

Three useful items: medicines, reports, and the note.

What to ask before choosing care

Start with the likely cause of the soreness. Ask which home measures remain worth trying. Medicine, physical therapy, or less strain may be discussed. Then ask what the care will involve. Cover possible harm, price, and return visits. Learn who will answer later questions. It's fine to think after leaving the office. You don't need to choose during the first talk.

Clear answers make the decision easier.

Evidence sources

1. A network meta-analysis restricted to LARGE randomized trials (at least 100 patients per group; 57 RCTs, 22,795 participants, 18 intra-articular interventions) found treatment effects were consistently larger in the 35 high-risk-of-bias trials than in the 22 low/unclear-risk trials. In the main analysis excluding high-risk trials, triamcinolone had the highest probability of exceeding the minimal important difference at weeks 2 and 6; hyaluronic acid had no effect on pain (SMD -0.04, 95% CrI -0.19 to 0.11, 11 trials) but higher odds of dropouts due to adverse events (OR 2.01) and of serious adverse events (OR 1.86). The effects of 16 of the 18 interventions were smaller than the MID and most were consistent with placebo effects.

2. A fragility-index analysis of the RCTs underpinning PRP for knee OA (1,993 patients) found the mean number of outcome events needed to reverse an individual trial's statistical significance was only 4.57, and 8.67 for the pooled meta-analytic effects. On meta-analysis PRP did show an advantage over hyaluronic acid (OR 2.19) and higher rates of achieving the MCID for pain versus alternatives (OR 6.19) - but the conclusions rest on a small number of events, which is the technical way of saying the literature is not robust.

3. A meta-analysis of the PLACEBO arms of 73 double-blind trials (5,895 patients) quantified what a saline knee injection alone achieves: statistically and clinically significant improvement in pain, function and quality of life at 1, 3 and 6 months, with responder rates exceeding 50% at all three time points, peaking around 4-8 months and declining by 12 months. Placebo response was stronger in trials with more female participants and in more recently published trials.
