Knees – Comprehensive Guide

Comprehensive Knees Guide

What is Knees?

The knee is a complex hinge joint that connects the thigh bone (femur) to the shin bone (tibia). It is essential for movement and stability, allowing activities like walking, running, and jumping. The knee also includes smaller bones like the patella (kneecap) and fibula, supported by cartilage, ligaments, tendons, and muscles.

Anatomy and Physiology

System: Musculoskeletal System.

• Musculoskeletal System: The knee joint is supported by bones, cartilage, ligaments (e.g., ACL, PCL), tendons, and muscles that provide stability and allow movement.
• Nervous System: Nerves like the femoral and tibial nerves supply the knee for sensation and coordination.

Signs and Symptoms

• Pain: Aching, sharp, or throbbing pain in the knee area.
• Swelling: Fluid buildup causing stiffness or visible enlargement.
• Stiffness: Difficulty bending or straightening the knee.
• Instability: Feeling of the knee giving way during movement.
• Locking: The knee gets stuck in a position and cannot move freely.
• Redness/Warmth: Inflammation or infection-related signs.
• Grinding/Popping: Noises during movement, often from cartilage issues.

Illnesses and Conditions

• Osteoarthritis: Degeneration of joint cartilage causing pain and stiffness.
• Rheumatoid Arthritis: An autoimmune condition leading to inflammation.
• Torn Ligaments (ACL/PCL/MCL): Injury to the ligaments stabilizing the knee.
• Meniscus Tear: Damage to the cartilage cushioning the joint.
• Patellar Tendinitis: Inflammation of the tendon connecting the kneecap to the shin.
• Bursitis: Swelling of the bursae, small fluid-filled sacs around the knee.
• Knee Fractures: Broken bones due to trauma or accidents.
• Runner’s Knee (Patellofemoral Pain Syndrome): Pain due to overuse or misalignment.

Health Issues Causes

General Causes:
Knee health issues arise from injuries, overuse, aging, or underlying medical conditions.

Specific Causes:

• Injuries: Sports accidents, falls, or sudden twisting motions.
• Overuse: Repetitive activities like running or squatting.
• Obesity: Excess weight adding pressure to the knee joint.
• Age-related Wear: Degenerative changes like osteoarthritis.
• Autoimmune Diseases: Conditions like rheumatoid arthritis causing inflammation.

Diagnosis and Checkups

• Physical Examination: Assessing movement, stability, and swelling.
• Imaging Tests: X-rays (for bones), MRI (for soft tissues), or CT scans for detailed visuals.
• Ultrasound: Evaluates soft tissue injuries.
• Arthroscopy: Minimally invasive procedure to examine and treat knee issues.
• Blood Tests: Detect autoimmune or infection-related causes.
• Joint Fluid Analysis: Identifies infection, gout, or inflammation.
