1. Joint Injuries

2. Today’s Agenda • Shoulder Joint Injuries • Knee Joint Injuries • Ankle Joint Injuries

3. Shoulder Joint Injuries Bicep Tendinitis • It is an overuse injury • This happens when the biceps brachii has not been given enough rest when it has been overused or overloaded • Symptoms include pain on the proximal end of the biceps which make flexion of the shoulder and elbow painful

4. Shoulder Joint Injuries Shoulder Separation • It is tearing of the acromioclavicular ligament • These injuries occur from a direct fall on the shoulder Shoulder Dislocations • This occurs when the humerus “pops out” of the glenoid fossa • This occurs from a hit or fall resulting a tear to the glenohumeral ligaments and joint capsule

5. Shoulder Joint Injuries Rotator Cuff Tears • It involves one or all four muscles of the rotator cuff: supraspinatus, infraspinatus, teres minor and subscapularis • When a tendon is torn, one or all of these muscles are affected • When a tear occurs, it hard to abduct and laterally or medially rotate the shoulder

6. Knee Joint Injuries Knee ligament tears • Most common involve “blows” to the lateral side of the knee, typically knee damage will result to the medial side • The first tissue to tear is the joint capsule • Depending on the severity of the injury damage to the medial collateral ligament, the medial meniscus and anterior cruciate ligament (ACL) will occur

7. Knee Joint Injuries Knee Ligament Tears • Q-angle may contribute to the predisposition of ACL tears • Proper stretching and strengthening will decrease the chance of injury

8. Knee Joint Injuries Osgoode - Schlatter Syndrome • Affects the epiphyseal plate of the tibial tuberosity • It is known as growing pains for a child • The growth plates can inflamed and irritated if overused or overloaded • Symptoms of this syndrome are swelling and discomfort

9. Knee Joint Injuries Patellofemoral Syndrome • Gradual onset of anterior knee pain/pain around the patella • Overuse, overloading and misuse of the patellofemoral joint will set off pain in the knee • The pain is aggravated by sports such as running, volleyball and basketball

10. Ankle Joint Injuries Inversion Sprains • It is commonly known as “rolling over on your ankle” or “twisted ankle” • It is most unstable during plantar flexion • This injury occurs when you jump in the air, or plant hard to change your direction causing the ankle to be inverted past the joint’s normal range of movement

11. Ankle Joint Injuries Eversion Sprains • It is a rare injury • Occurs to the deltoid ligament • This ligament is so strong, that only tears the tip of the medial malleolus • Pott’s Fracture • A force on the medial side of ankle causing the deltoid ligament to rip off the tip of the medial malleolus; and a break of the fibula
