Maintaining Healthy Knee Joints: A Comprehensive Guide

How Load is Distributed on the Joints of the Supporting Limbs

The joints of the supporting limbs, particularly the knee joints, bear a significant portion of the body’s weight. The knee is a complex hinge joint that absorbs shock and allows for movement. When standing, walking, or running, the load on the knee can be up to 1.5 times the body weight, and this can increase to 3-4 times during activities like stair climbing or jumping. Proper alignment and muscle strength are crucial to distribute this load evenly and prevent undue stress on any part of the knee.

What You Need to Know About Knee Joints

The knee joint is one of the largest and most complex joints in the body. It connects the thigh bone (femur) to the shin bone (tibia) and includes the patella (kneecap). The joint is cushioned by cartilage and synovial fluid, which reduces friction and absorbs shock. Ligaments and tendons provide stability and support. Common issues affecting the knee include arthritis, meniscus tears, ligament injuries, and tendonitis.

Tips for Maintaining Healthy Knee Joints

1. Maintain a Healthy Weight: Excess weight increases stress on the knee joints.
2. Stay Active: Regular exercise strengthens the muscles around the knee and improves flexibility.
3. Use Proper Technique: Ensure proper form during physical activities to avoid injury.
4. Wear Supportive Footwear: Good shoes provide proper alignment and shock absorption.
5. Avoid Prolonged Inactivity: Sitting for long periods can lead to stiffness and weakness.

Prevalence of Knee Problems

Approximately 25% of adults experience knee pain, with the prevalence increasing with age. Knee problems are more common in women than men, and risk factors include obesity, previous injuries, and certain occupations or sports.
