What is the Rate of Response to Nonoperative Treatment for Hip-Related Pain? A Systematic Review With Meta-analysis.

A team of researchers looked at 26 studies involving over 1,100 people with nonarthritic hip pain—the kind that isn't caused by osteoarthritis but might stem from conditions like femoroacetabular impingement, labral tears, or hip dysplasia. They wanted to know how many people actually get better with physical therapy and other nonsurgical treatments, and whether certain therapy approaches work better than others. What they found was that about 54 percent of people reported satisfactory improvement with nonoperative care, and on average, people saw small to moderate improvements in their symptoms and pain levels.

However, the research didn't reveal which specific ingredients of treatment actually drive that improvement, leaving open the question of what exactly makes the difference for the people who do respond well.

This study looked at what happens when people with hip pain get treated without surgery. The researchers reviewed all the research they could find and discovered that a bit over half of people who tried physical therapy and other nonsurgical approaches reported being satisfied with their results.

People generally did see some improvement in their symptoms and pain levels, though the gains were usually modest rather than dramatic. The catch is that researchers still don't have clear answers about which specific exercises, techniques, or treatments are the most important pieces of the puzzle.

This means your treatment may help, but we don't yet fully understand which parts of it matter most, so your physiotherapist may need to work with you to find what works best for your particular situation.

This meta-analysis offers a realistic snapshot of nonoperative treatment outcomes for nonarthritic hip conditions, with moderate certainty evidence suggesting a 54 percent satisfactory response rate across the pooled studies. The mean improvements on symptom and pain scales were in the small-to-modest range, with notably wider confidence intervals on pain measures indicating considerable heterogeneity in results.

What's notably absent from the findings is clarity on mechanism: the review found no definitive specific effect of therapy duration or specific components like flexibility work, movement pattern training, or mobilization, each reported with very low to low certainty. This suggests either that the elements of effective treatment are more complex or context-dependent than current research captures, or that the studies included in the review were too diverse in their protocols to reveal clear patterns.

The low certainty evidence for supplementary interventions like injections and bracing further underscores that while nonoperative treatment works for some patients, we're still identifying what makes it work for whom.
