4 Essential Ways to Keep Your Knees Healthy and Strong

Healthy knees play an important role in everyday movement, from walking and climbing stairs to exercising and performing routine activities. The knee joint supports much of the body's weight and allows the legs to bend, straighten and move comfortably.

As we age, the knee joint and surrounding structures may undergo natural changes. Factors such as excess body weight, previous injuries, muscle weakness, inactivity and certain medical conditions can also affect knee health.

Although not all knee problems can be prevented, adopting healthy habits can support joint function, strengthen the muscles around the knees and help maintain mobility.

Dr. Naveen Malu, Orthopedic Surgeon, shares four important ways to support healthy knees and reduce the risk of common knee problems.

1. Exercise Regularly to Strengthen Your Knee Joints

Regular physical activity helps maintain the strength and flexibility of the muscles that support the knee joint. Strong quadriceps, hamstrings and calf muscles help stabilise the knee and support everyday movements.

Low-impact exercises can be a suitable option for people who want to stay active while limiting excessive stress on their joints.

Some exercises that may support knee strength include:

• Straight leg raises: Lie on your back with one knee bent and the other leg straight. Slowly lift the straight leg, hold briefly and lower it in a controlled manner.

• Quadriceps strengthening: Sit on a chair and slowly straighten one knee. Hold the position briefly before lowering your leg.

• Hamstring stretches: Gently stretch the muscles at the back of your thigh to improve flexibility.

• Swimming: Water-based exercise allows movement with less weight-bearing stress on the knees.

• Stationary cycling: Cycling at a comfortable resistance can help maintain leg strength and joint movement.

Walking and other low-impact activities may also be beneficial, depending on your joint condition and fitness level.

Start gradually and increase activity according to your comfort. If an exercise causes significant pain or swelling, stop and consult a healthcare professional. People with existing knee conditions or previous injuries should seek guidance before beginning a new exercise programme.

2. Maintain a Healthy Body Weight

Body weight can influence the amount of pressure placed on the knee joints during everyday activities. Excess body weight may increase the mechanical load on the knees and contribute to discomfort, particularly while walking, climbing stairs or standing for long periods.

Maintaining a healthy weight can help reduce stress on the knee joints and may improve symptoms in people with knee osteoarthritis.

A combination of balanced nutrition and regular physical activity can support healthy weight management.

Consider these habits:

• Include vegetables, fruits and whole grains in your daily meals.

• Choose protein sources such as pulses, eggs, fish and lean meats.

• Include healthy fats in appropriate quantities.

• Limit frequent consumption of highly processed foods and sugary drinks.

• Stay physically active according to your ability.

• Follow realistic and sustainable weight-management goals.

Even gradual weight changes may be helpful for people who are overweight. Avoid extreme diets or sudden increases in exercise. A doctor or qualified nutrition professional can help you choose an appropriate approach.

3. Follow a Balanced Diet for Bone and Joint Health

Nutrition is an important part of maintaining healthy bones and supporting overall musculoskeletal health. Your body needs several nutrients to maintain bone strength and normal muscle function.

Some important nutrients include:

Calcium: Calcium supports bone structure and strength. Good dietary sources include milk, curd, cheese, ragi, tofu and certain leafy green vegetables.

Vitamin D: Vitamin D helps the body absorb calcium and supports bone health. It can be obtained through appropriate sunlight exposure and foods such as egg yolks, fatty fish and fortified products. Supplements may be recommended when a deficiency is identified.

Protein: Protein supports muscle maintenance and repair. Include foods such as lentils, beans, dairy products, eggs, fish and lean meat as part of a balanced diet.

Vitamin C: Vitamin C supports collagen formation, which is important for connective tissues. Citrus fruits, guava, tomatoes and bell peppers are useful sources.

Omega-3 fatty acids: These fats are found in foods such as oily fish, walnuts and flaxseeds. Including them as part of a balanced diet supports overall health.

A varied diet that includes different food groups can help meet your nutritional needs. However, no single food or supplement can prevent or cure knee conditions. Nutritional supplements should be taken when appropriate and after discussing them with a healthcare professional.

4. Protect Your Knees During Everyday Activities

Daily habits can influence knee comfort and function. Taking care of your knees during exercise, work and routine activities may help reduce avoidable strain.

Here are some practical measures:

• Use proper exercise techniques: Maintain correct posture and movement while performing strength-training exercises.

• Warm up before activity: Gentle movements prepare the muscles and joints for exercise.

• Wear suitable footwear: Comfortable, supportive footwear can help with stability during walking and physical activity.

• Avoid sudden increases in activity: Increase exercise duration and intensity gradually.

• Take breaks when needed: Avoid remaining in the same position for prolonged periods.

• Use proper lifting techniques: Bend at the hips and knees while keeping the load close to your body, rather than putting unnecessary strain on your joints.

If you participate in sports or physically demanding activities, appropriate training and recovery are important. Do not ignore persistent knee pain, swelling, stiffness or difficulty bearing weight.

When Should You Consult an Orthopedic Surgeon?

Occasional knee discomfort may occur after physical activity. However, persistent or worsening symptoms should be evaluated by an orthopedic surgeon.

Consider seeking medical advice if you experience:

• Repeated knee pain or swelling.

• Stiffness that affects movement.

• Difficulty walking or climbing stairs.

• A feeling that the knee is unstable or gives way.

• Reduced range of motion.

• Pain following a fall or sports injury.

Sudden severe pain, significant swelling, inability to bear weight, visible deformity or a hot, red knee accompanied by fever requires prompt medical assessment.

An orthopedic surgeon may recommend a physical examination and, when necessary, imaging investigations to identify the cause of your symptoms. Treatment depends on the diagnosis and may include physiotherapy, activity modification, medication or other suitable interventions.
