An ACL injury involves damage to the anterior cruciate ligament in the knee, commonly caused by sudden stops, twists, or impacts during sports activities. This injury can lead to knee instability, pain, swelling, and difficulty with movement. Rehabilitation for an ACL injury focuses on reducing pain and swelling, restoring range of motion, and strengthening the muscles around the knee through physical therapy. 

An ankle sprain occurs when the ligaments in the ankle are stretched or torn, often due to an awkward twist or roll of the foot. This injury can cause pain, swelling, bruising, and difficulty bearing weight on the affected foot. Rehabilitation for an ankle sprain focuses on reducing pain and swelling, restoring range of motion, and strengthening the muscles around the ankle through physical therapy.

Cervical whiplash is an injury to the neck caused by a sudden jerking motion, often occurring in car accidents or other trauma. It results in damage to the muscles, ligaments, and tendons in the neck, causing pain, stiffness, headaches, and limited mobility. 

Elbow pain in Little League pitchers, often referred to as Little League elbow, is an overuse injury caused by repetitive throwing motions that stress the growth plates in the elbow. This condition can result in pain, swelling, and reduced throwing ability. Rehabilitation focuses on rest, activity modification, physical therapy to improve arm strength and flexibility, and proper pitching mechanics to prevent further injury and ensure a safe return to play. 

Tennis elbow, or lateral epicondylosis, is a common painful condition that affects the tendons that join the forearm muscles on the outside of the elbow. This condition can cause pain, stiffness, and weakness in the forearm and hand, sometimes accompanied by nerve compression symptoms like numbness or tingling.

Iliotibial band syndrome is a common overuse injury, typically seen in runners and athletes, caused by irritation or inflammation of the iliotibial band, a thick band of tissue that runs along the outside of the thigh. It leads to pain and tenderness on the outer side of the knee or hip, often worsened by repetitive motion.

Shoulder impingement syndrome occurs when the tendons or bursa in the shoulder become compressed or irritated, leading to pain, weakness, and limited range of motion. It is often caused by repetitive overhead movements, inflammation, or structural abnormalities.

Medial and lateral collateral ligament (MCL and LCL) injuries occur when the ligaments on the inner (MCL) or outer (LCL) side of the knee are stretched or torn, often due to sudden twists, impacts, or forceful movements. These injuries lead to pain, swelling, instability, and difficulty with knee movement.

A mild traumatic brain injury is typically caused by a blow or jolt to the head, leading to temporary disruptions in brain function. Symptoms can include headaches, dizziness, memory problems, and difficulty concentrating. Rehabilitation, including physical, cognitive, and psychological therapies, is often essential in helping individuals recover and return to normal activities while managing symptoms and preventing long-term complications. 

Patellofemoral syndrome, also known as "runner's knee," is a condition characterized by pain around the front of the knee, often caused by improper tracking of the patella (kneecap) in the femoral groove. This condition is commonly seen in athletes or individuals who engage in repetitive knee movements. Rehabilitation focuses on reducing pain and inflammation, improving knee alignment, and strengthening the muscles around the knee, more specifically the quadriceps.

Plantar fasciitis is a common cause of heel pain, caused by inflammation of the plantar fascia, a thick band of tissue that runs along the bottom of the foot. This condition typically results in sharp pain, especially with the first steps in the morning or after long periods of standing. Proper footwear, orthotics, and activity modification may be helpful measures to prevent recurrence and relive symptoms.

Proximal and mid-hamstring strains or tendon tears occur when the hamstring muscles, located at the back of the thigh, are overstretched or torn, often due to sudden movements like sprinting or jumping. This injury can cause pain, swelling, bruising, and difficulty with leg movement.

Athletes and individuals who engage in repetitive overhead motions are at increased risk for shoulder tendon and muscle injuries. These injuries often involve the rotator cuff, biceps tendon, or other muscles around the shoulder joint, leading to pain, weakness, and limited range of motion.

Sports concussions are brain injuries that result from a blow to the head. Concussions are most common in boys playing football and girls playing soccer, but any sport can result in concussion. It is important that athletes be seen by a physician after any blow to the head.

Tendinopathy refers to the degeneration or inflammation of a tendon, often caused by overuse or repetitive strain. Also known as tendinitis, this condition can lead to pain, swelling, and reduced function in the affected area, commonly affecting the shoulder, elbow, and wrist.
