- A meta-analysis finds that adding hip exercises to quadriceps exercises improves walking, pain, and overall function in people with knee osteoarthritis (KOA).
Why this matters
- KOA is the chief cause of pain and disability among adults.
- Hip exercises have been overlooked in importance for people with KOA as a means to improve pain and disability, considering that weak hip abduction is seen in up to 1 in 4 individuals.
- Meta-analysis of 8 studies (n≥300) was conducted after a search of Medline, EMBASE, Cochrane, CINAHL, and SportDiscus databases.
- Funding: No external.
- Combined hip and quadriceps exercises are more effective than quadriceps exercises alone to improve walking (standardized mean difference, −1.06; 95% CI, −2.01 to −0.12), but not to improve pain, patient-reported function, or stair function.
- Subgroup analysis of hip resistance exercises finds that they are superior to hip functional neuromuscular exercises for improving pain (P<.0001 and patient-reported function>
- Subgroup analysis of hip multimodal exercise finds that it is not superior to quadriceps alone strengthening for pain, patient-reported function, or stair function.
- Few studies, participants.
