Understanding Hip Contact Stress Based on Types of Physical Activity: A Systematic Review.

Area of Science:

• Biomechanics
• Orthopedics
• Sports Medicine

Background:

• High hip contact stress is a known risk factor for hip osteoarthritis (OA).
• Previous research has identified OA risk factors but lacked a holistic approach to hip contact stress contributors.
• Understanding the link between physical activity and hip contact stress is crucial for OA prevention.

Purpose of the Study:

• To comprehensively understand the effects of physical activity on high hip contact stress.
• To identify physical activities that may predispose individuals to hip OA through increased contact stress.

Main Methods:

• Systematic review registered with PROSPERO (CRD42022296638) following PRISMA guidelines.
• Searched PubMed, Web of Science, and Scopus for articles on hip contact stress, force, and pressure.
• Analyzed factors, experimental designs, results, and evidence from 21 eligible studies.

Main Results:

• 21 studies were included after screening 7972 papers.
• Various types of physical activity correlate with high hip joint contact stress.
• More intense activities, such as running and stair climbing, showed a greater impact on increasing hip contact stress values.

Conclusions:

• Physical activity intensity is linked to elevated hip contact stress.
• The reviewed studies exhibit methodological variations, indicating a need for more standardized research.
• This area requires further investigation to establish definitive causal links and inform OA prevention strategies.
