Knee Pain: Understanding the Causes and Treatment

The human knee, the largest and most intricate joint in the body, bears substantial daily loads. Consequently, knee pain ranks among the most prevalent joint issues.

Probable Causes behind Severe Knee Pain and Possible Treatments Available

While injuries from activities like running are common, knee pain can also arise from over ten different conditions. This article delves into the primary sources of knee pain and methods for managing it.

What Makes Knees So Vulnerable?

The knee joint is one of the human body’s most extensive and intricate joints. It is pivotal in facilitating movement – encompassing walking, running, and jumping. This joint endures immense strain, particularly during walking, where it bears the entire body’s weight.

Moreover, the knee’s susceptibility becomes apparent in modern sports. A range of contemporary athletic activities can aggressively impact the knee joints. The primary culprits contributing to knee joint damage are:

Running
Jumping
Powerlifting
Boxing, fighting
Skiing

It’s worth noting that even in the absence of overt damage, the knee’s articular structures, most commonly the meniscus, can undergo micro traumatization. For instance, running on hard surfaces can lead to degenerative alterations in the knee’s articular structures.

Common Contributors to Knee Pain

Pain in the knee joint can be caused by a number of pathological processes – inflammation of the joints and ligaments, tissue wear, systemic autoimmune or metabolic disorders.

Sports-Related Injuries

Sports injuries are frequent occurrences among athletes. Ligament tears in the knee joint often accompany sudden knee pain. Activities such as running, jumping, and cycling can lead to “runner’s knee” or friction syndrome inside the joint.

This syndrome, characterized by patella pain, results from excessive stress, injury, leg bone conditions, or muscle weakness. While some athletes resort to a knee compression sleeve and pain relievers, it’s crucial to seek medical advice to prevent potential exacerbation.

Joint Conditions

Several joint-related conditions can trigger knee pain:

Rheumatism: A painful condition typically affecting one knee at a time, prevalent among teenagers and individuals recently recovering from streptococcal infections.
Reactive arthritis: Inflammation striking people aged 25-35, causing internal, external, anterior, posterior, or bottom knee pain, often accompanied by swelling and redness.
Reiter’s syndrome: Symptoms mirroring reactive arthritis, with additional urethritis and intestinal issues.
Osteoarthritis: Affecting the elderly, it brings aching knee pain exacerbated by weather changes, occurring at night and while walking.
Osgood-Schlatter’s disease: Pain during bending, stair climbing, and squats.
Rheumatoid arthritis: Autoimmune condition featuring significant swelling and unbearable front-of-knee pain, especially at night.
Bursitis: Inflammatory knee processes marked by swelling, intensified at night and with strenuous activities.
Gout: Linked to an imbalanced diet, excessive junk food, and alcohol consumption, causing persistent, achy patella pain.

Internal Pathologies

Knee pain may result from internal organ issues in the lumbar or sacral region, leading to referred pain. In this scenario, knee joint palpation or movement won’t elicit pain, but discomfort could heighten with changes in body position or spinal load.

A comprehensive examination is necessary for accurate diagnosis.

Psychosomatic Influences

Psychosomatic factors like stress, anxiety, and nervous tension can cause muscle and joint tension, including knee pain. Emotional reactions like depression and anxiety disorders could affect the nervous system, inducing discomfort and pain.

Notably, psychosomatic pain doesn’t rule out physical damage, so seeking medical consultation is always a good idea.

Deciphering Pain Origins by Location and Nature

Pain localisation (under, above, inner, outer, central, or posterior knee) and its nature during specific actions can hint at the underlying cause. For instance:

Intense pain beneath the knee could stem from inflamed ligaments connecting the lower leg and kneecap.
Outer or inner pain suggests lateral ligament or meniscus damage.
Acute knee pain unrelated to injury might signify chronic pathology exacerbation, infectious inflammation, or rheumatism development.
Fluctuating pain might point to muscle, ligament overexertion, cartilage or tendon inflammation, biomechanical imbalances, or incorrect body positions.

Regardless of the scenario, the most prudent approach entails consulting a medical professional. The self-treatment may include full immobilisation of the affected limb, including the joint, and administration of a cold compress. Then you need to see a doctor for further instructions.

Seeking Relief: Treating Knee Pain

Knee pain is treated according to its underlying cause. Medical professionals might suggest physical therapy, braces, targeted knee joint exercises, and non-steroidal anti-inflammatory drugs for pain relief.

In severe cases, cortisone injections, antibiotics, antirheumatic drugs, and tailored osteoporosis treatments could be administered.

In instances of significant injuries, surgical interventions might be necessary:

Meniscal damage: If joint mobility becomes restricted and conventional treatment methods prove ineffective, the affected region might need to be excised, or the meniscus segments sutured together. This approach is often advised for individuals actively participating in sports, particularly those in their youth.
Cartilage damage: The capacity to regenerate cartilage tissue in adults and the elderly is limited. Consequently, in cases involving joint deterioration, interventions that stimulate restoration or substitute damaged tissue segments are recommended.
Ligament impairment: Surgical intervention is deemed necessary when knee joint stability is compromised, thereby impacting the individual’s ability to walk or engage in sports activities.
Patella dislocation: Surgical treatment becomes imperative if the potential for re-injury exists or if the joint’s anatomical attributes necessitate such intervention.
Infectious inflammation: Drainage procedures may be required for some inflammatory conditions necessitating fluid removal.
Joint replacement: Replacement surgery may be considered in select cases where other interventions prove inadequate.

Preventing Knee Pain: Embracing a Healthy Lifestyle

Making certain adjustments to your lifestyle can significantly contribute to preventing knee pain and maintaining overall joint health. Here are some lifestyle changes to consider:

Maintain a healthy weight: Excess body weight places additional stress on the knees. By maintaining a healthy weight, you can minimise knee joint pressure.
Stay active and exercise regularly: Engage in low-impact exercises such as swimming, walking, and cycling. They can help strengthen muscles that support the knee joint and improve joint flexibility.
Warm-up and cool down: Always warm up before exercising to get your muscles and joints ready for movement. Cooling down after exercise can aid in preventing stiffness and soreness.
Invest in quality footwear: Choose shoes with good arch support and cushioning, especially if you’re engaging in activities that involve impact on the knees.
Practise good posture: Maintain proper posture while standing, sitting, and walking. Proper alignment can reduce unnecessary strain on the knees.
Avoid prolonged sitting: If you have a sedentary job, take breaks to stand, stretch, and move around to prevent stiffness.
Incorporate strength training: By strengthening quadriceps and hamstrings (muscles around the knee joint), you can improve joint stability and reduce injury risks.
Stretch regularly: Incorporate regular stretching into your routine to improve flexibility and maintain a full range of motion in your joints.
Stay hydrated: Drinking enough water helps maintain joint lubrication and overall joint health.
Include Omega-3s: Omega-3 fatty acids have anti-inflammatory properties that can benefit joint health.
Manage stress: Stress and tension can lead to muscle tightness and affect joint health. Relaxation techniques like deep breathing, meditation, and yoga can help manage stress.
Listen to your body: Pay attention to any discomfort or pain in your knees. If you experience persistent pain, it’s important to rest and consult a healthcare professional.
Maintain a balanced diet: Include more fruits, vegetables, whole grains, and lean proteins in your diet. Adequate nutrition supports overall joint health.
Avoid overexertion: Know your limits and avoid pushing yourself too hard during exercise or physical activities.
Regular check-ups: Make regular appointments with your healthcare provider to monitor joint function and address any concerns.

By adopting these lifestyle changes, you can take proactive steps to prevent knee pain, improve joint health, and enhance your overall wellbeing. However, when pain occurs, consulting a medical professional remains the most prudent course of action for effective diagnosis and personalized treatment.
