Exercise as a treatment for osteoarthritis.

Area of Science:

• Orthopedics
• Sports Medicine
• Rehabilitation

Background:

• Osteoarthritis (OA) is a prevalent joint disease, with knee OA being particularly common.
• Exercise plays a vital role in managing OA symptoms and potentially slowing disease progression.
• Current research emphasizes exercise for symptomatic relief, with growing interest in its preventive and disease-modifying roles.

Purpose of the Study:

• To review recent research, clinical applications, and future directions for exercise in osteoarthritis management.
• To focus on knee osteoarthritis due to its high prevalence and research focus.
• To examine exercise prescription for symptomatic relief and its potential role in OA prevention and progression.

Main Methods:

• Systematic review of meta-analyses and relevant studies on exercise and osteoarthritis.
• Analysis of exercise prescription, delivery modes, and patient subgroups.
• Evaluation of emerging research on exercise for OA prevention and progression.

Main Results:

• Meta-analyses confirm exercise is essential for OA management, with benefits enhanced by interventions like weight loss.
• Supervised exercise sessions are more effective for pain reduction than home-based exercises.
• Emerging evidence suggests strength training and hip muscle strengthening may prevent knee OA, especially in women.

Conclusions:

• Future research should identify cost-effective exercise modalities and strategies to improve patient adherence.
• Investigating the role of muscle strength and neuromuscular control in OA prevention and development is crucial.
• Developing and testing novel exercise interventions targeting these factors is a key future direction.
