2. Knee pain

   • causes
     • Injuries
       • ACL injury
       • Fractures
       • Torn meniscus
       • Knee bursitis
       • Patellar tendinitis
     • Mechanical Pain
       • Loose body
       • Iliotibial band syndrome
       • Dislocated kneecap
       • Hip or foot pain
     • Arthritis
       • Osteoarthritis
         • chronic disease characterized by progressive degeneration, destruction, and loss of articular cartilage.
           • Primary
             • in the elderly without an obvious cause
           • Secondary
             • Affects joints damaged by another disease
               • Pathology
                 • Progression
                   • Prognosis
                     • Unpredictable
                     • Depends on joint affected and progression
                     • 40% of old OA patients have x-ray evidence revealing significant OA in their hips and knees
                     • less than 5% will undergo joint replacement surgery.
         • Risk Factors

             • Injury/Surgery
             • Occupation
             • Physical Activity
             • Mechanical factors

             • Diet
         • common clinical features
           • Pain, dull and deep seated
           • Stiffness of joints,
           • Crepitus, a sound elicited by the opposing joint surfaces
           • Swelling and effusion
           • Heberden nodes involving the finger joints
         • Complications
           • Chondrolysis
           • Osteonecrosis
           • Stress fractures
           • Loss of ability
           • Hemorrhage within the joint
           • Infection
           • Compression of vertebral artery
           • Osteophyte pressing on the esophagus
           • Atrophy
           • Baker’s Cyst (popliteal cysts)
         • Treatment and management
           • Non- pharmacological treatment
             • Life style
             • Exercise
             • Aids and appliances
             • Patient education
             • Heat and cold
             • Weight loss
           • pharmacological treatment
             • Glucosamine is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids
               • It is in the fluid that is around joints.
                 • Can be given to:
                   • Relief the pain within 4-8 weeks NSAIDS “ibuprofen” within
                   • Improve joint function
                   • Slow breakdown of joints
           • Surgery
             • knee Joint replacement
               • surgery to replace a knee joint with a man-made joint. The artificial joint is called a prosthesis.
