Knee Pain Causes

Knee Pain Causes: An In-Depth Guide from a Physiotherapist's Perspective

Knee pain is a common complaint that can significantly impact your daily life. Understanding the causes of knee pain is crucial for effective treatment and prevention. This guide explores various knee pain causes and provides insights from a physiotherapist's perspective.

Common Causes of Knee Pain

Knee pain can stem from a variety of sources, ranging from acute injuries to chronic conditions. Let's explore some common causes:

Ligament Injuries

Ligament injuries are a significant cause of knee pain. These injuries often occur during sports or high-impact activities.

• ACL Injury: The Anterior Cruciate Ligament (ACL) is crucial for knee stability. ACL injuries can result from sudden stops or changes in direction. Symptoms include pain, swelling, and instability. Treatment often involves surgery and rehabilitation.
• PCL Injury: The Posterior Cruciate Ligament (PCL) can be injured in direct trauma to the knee. This injury also leads to pain and swelling, with treatment options ranging from physical therapy to surgery.
• MCL and LCL Sprains: Medial Collateral Ligament (MCL) and Lateral Collateral Ligament (LCL) sprains result from direct blows to the knee. These injuries cause pain and instability, often requiring rest, bracing, and physiotherapy.

Meniscus Injuries

Meniscus tears are another common knee injury. The meniscus is a cartilage that cushions the knee joint.

• Meniscus Tear: This injury often occurs from twisting or rotating the knee while bearing weight. Symptoms include pain, swelling, and difficulty moving the knee. Treatment options vary based on the tear's severity, ranging from rest and physiotherapy to surgery.
• Discoid Meniscus: This congenital condition results in an abnormally shaped meniscus, leading to pain and instability. Treatment may involve surgery to reshape or remove the meniscus.

Kneecap Pain

Several conditions can cause pain in the kneecap area, affecting your ability to perform daily activities.

• Chondromalacia Patella: Also known as "runner's knee," this condition involves the softening and breakdown of the cartilage on the underside of the kneecap. It causes pain and swelling, particularly when walking up stairs or sitting for long periods.
• Patellar Tendinopathy: Also called "jumper's knee," this condition results from overuse, causing pain at the front of the knee. Treatment typically includes rest, physiotherapy, and strengthening exercises.
• Patellofemoral Pain Syndrome: This condition involves pain around the kneecap, often resulting from overuse or misalignment. Treatment includes rest, physiotherapy to improve the patellar tracking, and proper footwear.

Knee Arthritis

Arthritis is a leading cause of knee pain, particularly in older adults. It causes inflammation and stiffness in the joints.

• Knee Osteoarthritis: This degenerative condition involves the wearing down of cartilage, leading to pain and swelling. Treatment includes physiotherapy, medication, and sometimes surgery.
• Rheumatoid Arthritis: This autoimmune condition causes inflammation in the knee joints. It requires medical management and physiotherapy to manage symptoms.

Knee Tendon Injuries

Tendon injuries can result from overuse or sudden, high-impact activities.

• Patellar Tendinopathy: This injury involves the patellar tendon, causing pain below the kneecap. Treatment includes rest, physiotherapy, and strengthening exercises.
• Quadriceps Tendinopathy: This condition affects the tendon connecting the quadriceps muscles to the knee, leading to pain above the kneecap.

Muscle Injuries

Muscle strains and related conditions are common knee pain causes, especially among athletes and active individuals.

• Hamstring Strain: This injury involves the muscles at the back of the thigh. It causes pain, swelling, and difficulty bending the knee. Treatment includes rest, ice, and physiotherapy.
• ITB Syndrome: The Iliotibial Band (ITB) can become tight and inflamed, leading to pain on the outer side of the knee. Stretching and physiotherapy are essential for recovery.

Knee Bursitis

Inflammation of the bursae, small fluid-filled sacs around the knee, can cause significant pain.

• Knee bursitis: Suprapatella bursitis is a common knee bursitis.
• Pes Anserine Bursitis: This condition involves inflammation of the bursa located on the inner side of the knee. It causes pain and swelling, with treatment focusing on reducing inflammation through rest, ice, and physiotherapy.

Children’s Knee Conditions

Young athletes can experience specific knee conditions related to growth and activity levels.

• Osgood Schlatter’s Disease: This condition involves inflammation of the area just below the kneecap where the tendon from the kneecap attaches to the shinbone. It causes pain and swelling, especially during activities.
• Sinding Larsen Johansson Syndrome: This condition affects the growth plate at the bottom of the kneecap, leading to pain and swelling.

Other Knee-Related Conditions

Various other conditions can lead to knee pain, necessitating a broad understanding of potential causes.

• Runner’s Knee: This condition involves pain around the kneecap, often resulting from overuse or misalignment. Treatment includes rest, physiotherapy, and proper footwear.
• Plica Syndrome: Inflammation of the plica, a fold in the knee lining, can cause pain and swelling. Physiotherapy and anti-inflammatory medications are common treatments.

What to Do?

If you're experiencing knee pain, seeking professional advice from a physiotherapist is essential. They can provide a personalised assessment and treatment plan to address your specific needs. Early intervention can significantly improve your outcomes and help you return to a pain-free, active lifestyle.

Conclusion

Understanding the causes of knee pain is the first step towards effective treatment. By addressing the root cause, you can find relief and prevent future issues. Consult a physiotherapist to develop a tailored plan for your knee health.
