Knee

The knee is a complex joint that connects the thigh bone (femur) to the shin bone (tibia). It is a critical component in our ability to perform everyday activities such as walking, running, jumping, and squatting. The knee comprises various structures, including bones, cartilage, muscles, tendons, and ligaments, which work together to provide stability and movement.

Knee Anatomy

1. Bones: The knee joint involves three bones: the femur, tibia, and patella (kneecap). These bones are essential for movement and support.
2. Cartilage: The knee contains two types of cartilage: articular cartilage, which covers the ends of the bones and allows them to glide smoothly, and the meniscus, which acts as a shock absorber between the femur and tibia.
3. Muscles and Tendons: Muscles around the knee provide strength and movement, while tendons connect these muscles to the bones.
4. Ligaments: Four main ligaments stabilize the knee: the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL).

Common Knee Conditions and Injuries

Knee pain is a widespread issue affecting people of all ages. It can result from trauma, overuse, or underlying medical conditions. Here are some prevalent causes of knee pain:

1. Traumatic Injuries:
   • ACL Tears: Often occur during sports involving sudden stops or changes in direction.
   • Meniscus Tears: Result from twisting or rotating the knee while bearing weight.
   • Knee Fractures: Breaks in the knee bones can occur from falls or direct blows.
   • Sprains and Strains: two common types of soft tissue injuries that can affect the knee.  Sprains affect the ligaments in the knee, while strains affect the muscles and tendons.  Both injuries can cause pain, welling and instability, but the specific tissues involved are different.
     • • Sprain: A sprain refers to an injury to the ligaments, which are the strong, fibrous tissues that connect bones to each other at joints. In the knee, this often involves damage to ligaments such as the ACL (anterior cruciate ligament), MCL (medial collateral ligament), or LCL (lateral collateral ligament). Sprains occur when these ligaments are overstretched or torn, typically due to sudden twisting motions, direct impacts, or awkward landings.
       • Strain: A strain involves injury to the muscles or tendons, which are the tissues that connect muscles to bones. In the knee, strains can affect muscles such as the quadriceps, hamstrings, or the tendons that support knee movement. Strains occur when the muscles or tendons are overstretched or torn, often due to overuse, sudden movements, or heavy lifting.
   • Subluxation or Dislocation: When the bones of the knee are forced out of alignment.
2. Medical Conditions:
   • Osteoarthritis: Degeneration of joint cartilage and underlying bone.
   • Rheumatoid Arthritis: An autoimmune disorder affecting the joints.
   • Gout: A form of arthritis caused by the accumulation of uric acid crystals.
   • Bursitis: Inflammation of the bursae, the small fluid-filled sacs that cushion the knee.
   • Bone Chips:
   • Osgood-Schlatter disease:
   • Osteochondritis dissecans:
   • Infected knee replacement:
   • Failed knee replacement:
3. Overuse Injuries:
   • Iliotibial Band Syndrome: Caused by repetitive friction of the iliotibial band over the outer knee.
   • Runner’s Knee: Pain around the kneecap often due to overuse.
   • Tendonitis (or Tendinitis): Inflammation or irritation of a tendon.
   • Chronic Knee Pain:  commonly associated with overuse of the knee during activities that involve running or jumping. In addition, trauma or injury may lead to chronic knee pain.
   • Cartilage Wear and Tear:

Symptoms of Knee Problems

Patients with knee issues may experience a range of symptoms, including:

• Pain and swelling
• Stiffness and reduced range of motion
• Weakness or instability
• Crunching or popping noises
• Inability to fully bend or straighten the knee

Diagnosis and Treatment Options

At Golden State Orthopedics & Spine (GSOS), we adopt a multi-faceted approach to diagnosing and treating knee conditions. Our award-winning medical doctors utilize advanced diagnostic tools and techniques to accurately assess knee problems.

Diagnostic Procedures

1. Physical Examination: Evaluating the knee’s range of motion, stability, and strength.
2. Imaging Tests: X-rays, MRI, and CT scans provide detailed images of the knee’s internal structures.
3. Arthroscopy: A minimally invasive procedure that allows doctors to view the inside of the knee joint using a small camera.

Prevention of Knee Injuries

Preventing knee injuries involves a combination of lifestyle adjustments and proper training techniques. Here are some tips to help reduce the risk of knee injuries:

1. Strengthening Exercises: Engaging in exercises that strengthen the muscles around the knee can provide better support and stability. Focus on quadriceps, hamstrings, and calf muscles.
2. Flexibility: Incorporating stretching exercises into your routine can improve flexibility and reduce the risk of injuries. Yoga and Pilates are excellent options for enhancing flexibility.
3. Proper Footwear: Wearing shoes that provide adequate support and cushioning can help absorb shock and reduce stress on the knees.
4. Warm-Up and Cool-Down: Always warm up before engaging in physical activities and cool down afterward. This helps prepare your muscles and joints for exercise and reduces the risk of injury.
5. Avoid Overuse: Gradually increase the intensity and duration of your activities to avoid overloading the knee joint. Listen to your body and take breaks when needed.

Living with Knee Pain

Living with knee pain can be challenging, but there are ways to manage symptoms and improve your quality of life. Here are some strategies:

1. Weight Management: Maintaining a healthy weight can reduce the stress on your knees and alleviate pain. Aim for a balanced diet and regular exercise.
2. Activity Modification: Adjusting your activities to avoid those that exacerbate knee pain can help manage symptoms. Low-impact exercises such as swimming and cycling are good alternatives.
3. Pain Management: Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can help manage pain and inflammation. Consult your doctor before taking any medication.
4. Assistive Devices: Using canes or crutches can help reduce the load on your knee and provide support during movement.
