Knee Pain and Injuries

Arthritis

Arthritis is a term used to describe a group of degenerative and inflammatory conditions primarily impacting the knee joint. These conditions often result in pain, stiffness and decreased range of motion.

• Gout and pseudogout: These conditions result from the deposition of urate crystals (gout) or calcium pyrophosphate crystals (pseudogout) in the knee joint, leading to sudden, intense pain, inflammation and swelling.
• Osteoarthritis: The most common type of arthritis, osteoarthritis, occurs as the protective cartilage in the knee gradually wears down over time. It's often linked to aging, joint overuse or previous injuries, leading to pain, swelling and joint instability.
• Rheumatoid arthritis: Unlike osteoarthritis, rheumatoid arthritis is an autoimmune disease where the body's immune system mistakenly attacks the synovium, the membrane lining the knee joint. It causes pain, inflammation and eventually joint deformity.
• Septic arthritis: Septic arthritis is when the knee joint becomes infected. It is an emergency characterized by severe pain, swelling, fever and limited mobility.

Injuries

Knee injuries are often the result of traumatic events or overuse, and they can cause acute or chronic pain.

• Bursitis: Inflammation of the bursae, the small sacs filled with fluid that cushion the knee joint, can lead to pain, swelling and limited range of motion.
• Dislocated kneecap: A dislocated kneecap can cause sudden, intense pain and instability, potentially leading to ligament damage or cartilage injury.
• Fractures: Broken bones around the knee can be extremely painful and may require surgery for optimal healing.
• Ligament tears: Injuries to ligaments like the Anterior Cruciate Ligament (ACL), Medial Collateral Ligament (MCL), Lateral Collateral Ligament (LCL), and Posterior Cruciate Ligament (PCL) can cause intense pain, instability and difficulty with weight-bearing.
• Meniscus tears: Tears often occur when the C-shaped cartilage in the knee gets damaged, resulting in sharp, localized pain, especially when twisting or squatting.

Overuse

Overuse injuries often develop gradually due to repetitive stress on the knee joint.

• Iliotibial band syndrome: Often experienced by runners and cyclists, it causes outer knee pain due to friction between the iliotibial (IT) band and the knee joint.
• Nerve compression: Conditions like sciatica can cause pain to radiate into the knee, leading to discomfort and reduced mobility.
• Obesity: Excess body weight puts added stress on the knee joint, increasing the risk of chronic pain and potentially accelerating the development of arthritis.
• Osgood-Schlatter Disease: Primarily affecting adolescents, Osgood-Schlatter Disease results in pain just below the kneecap, where the patellar tendon attaches to the shinbone due to irritation around the growth plate.
• Runner's knee: Patellofemoral pain syndrome, also known as runner's knee, causes dull, aching pain around the kneecap, particularly when going up or down stairs, squatting or sitting for extended periods.
• Swollen and inflamed tendons: Swollen tendons that connect muscles to bones can cause tendonitis, a pain in the knee during certain activities.

Understanding the specific cause of your knee pain is the first step toward effective management and treatment. If you're experiencing persistent knee pain, don't hesitate to consult a healthcare professional, such as an orthopedic specialist, who can perform a comprehensive evaluation, diagnose and create a personalized treatment plan tailored to your unique needs. Early intervention is key to maintaining the health and function of your knee joint.

Home remedies for knee pain

Effective at-home strategies to manage and alleviate knee discomfort can include:

• Rest and activity modification: Giving your knee adequate rest and modifying activities can significantly reduce the strain on the joint to promote recovery.
• RICE method: The rest, ice, compression and elevation protocol can help minimize pain and inflammation. Cold compresses can reduce swelling, while elevation facilitates fluid drainage from the affected area.
• Medications: Over-the-counter pain relievers, such as nonsteroidal anti-inflammatory drugs (NSAIDs), can relieve mild to moderate knee pain. In cases of more severe pain or inflammation, prescription medications may be recommended.
• Orthotics: Shoe inserts or braces can provide extra support and help correct alignment issues, reducing knee joint stress.
• Weight management: Maintaining a healthy body weight is key in reducing knee pain, particularly in cases of knee osteoarthritis. Shedding excess weight reduces the mechanical load on the knee, which lessens pain and improves function.

Minimally invasive knee treatments

Non-surgical interventions that offer effective solutions for various knee problems include:

• Arthroscopy: Arthroscopy is a minimally invasive procedure that uses a small camera (arthroscope) to visualize and treat various knee issues. It's often used to repair damaged cartilage or ligaments.
• Cortisone injections: These injections contain a potent anti-inflammatory corticosteroid that can provide temporary pain relief by reducing inflammation within the knee joint.
• Joint aspiration: In cases of excess synovial fluid (the liquid between joints), aspiration (draining the fluid) is performed to alleviate pain and reduce swelling to aid the diagnosis and management of the condition.
• Physical therapy: Tailored physical therapy exercises and stretches under the guidance of a physical therapist can enhance knee strength, flexibility and overall joint function.
• Platelet-rich plasma (PRP) therapy: PRP is a minimally invasive procedure that harnesses the body's natural healing properties by injecting a concentrated solution of platelets into the knee, promoting tissue repair and aiding in pain relief.
• Viscosupplementation: This non-surgical approach involves injecting a lubricating substance (hyaluronic acid) into the knee joint to reduce pain and improve mobility, especially in cases of knee osteoarthritis.

Surgery for knee pain

When conservative methods prove insufficient, surgical interventions like these can offer more definitive solutions:

• Cartilage repair: Many procedures aim to restore or replace damaged cartilage within the knee, promoting smoother joint movement and reduced pain.
• Kneecap replacement: Partial or complete replacement of the kneecap (patella) is an option for those with severe patellofemoral pain or damage.
• Ligament reconstruction: Surgical repair or replacement of damaged knee ligaments, often required after injuries like ACL tears, restores stability and function.
• Meniscus repair or removal: Addressing tears, damage or degeneration of the meniscus (the cartilage that acts as a cushion in the knee) is vital for improved joint function.
• Partial or total knee replacement: These surgical options involve replacing either the entire knee joint (a total knee replacement) or just one part (a partial knee replacement) with artificial components. These procedures are highly effective for those with severe arthritis, providing lasting pain relief and improved joint function.
