    Study Notes

    Female Athletes

    • Females and males have equal rates of injury incidence, but female athletes are more likely to experience structural injuries.
    • Common structural injuries in female athletes include ACL tears, PFS and Patella Subluxation, Spondylolysis and Spondylolisthesis, and Stress Fractures.
    • Hormonal and menstruation factors contribute to Spondylolysis and Spondylolisthesis in females.
    • The knee is particularly vulnerable to injuries in females due to pelvic differences, specifically the Q-Angle.

    Biomechanical Predisposition

    Knee Injuries

    • Females have a higher femoral obliquity (Q-Angle) which increases valgus force, leading to greater stress on medial structures like the MCL, meniscus, and ACL.
    • Female athletes have a smaller intercondylar notch, which can lead to more instability and hypermobility in the knee.
    • Females often have a weaker hamstring to quadriceps strength ratio, leading to decreased recruitment of the hamstrings and overreliance on the quadriceps.
    • Cyclical hormonal fluctuations impact collagen tissue remodeling, potentially degrading tissue during menstruation.

    Skeletal Differences

    Q-Angle

    • The Q-Angle in males is 13%, leading to increased medial tibiofemoral contact.
    • The Q-Angle in females is 18%, leading to increased lateral patellofemoral contact.

    Anterior Cruciate Ligament (ACL)

    • ACL injuries are more common in females, occurring 2-6 times more frequently than in males.
    • Mechanisms of ACL injury include valgus force, hyperextension, internal rotation of the femur, and deceleration.

    PFS and Patella Subluxation

    • Female athletes often have smaller patellas.

    Stress Fractures

    • Predisposing factors to stress fractures include overuse, poor mechanics, low bone density, nutrition deficiencies, and hormonal fluctuations.
    • Societal factors can also contribute, such as the idealization of a thin body, the pressures of working motherhood, and fashion trends like high heels which can contribute to shortened Achilles tendons and Hallux Valgus (toe inward)

    Prevention

    • Strengthening exercises for the legs.
    • Assessment of quadriceps and hamstring strength.
    • Education on posture and biomechanics.

    Hormonal Effects

    • Amenorrhea (lack of menstruation):

      • Primary Amenorrhea: No period by age 16. Stress Fractures are common in primary amenorrhea.
      • Secondary Amenorrhea: A previously regular period that has stopped. Can be pregnancy related.

    • Oligomenorrhea: Irregular menstrual cycle.

    • Anovulation: Not ovulating, leading to low estrogen levels.

    • Short Luteal Phase: The phase responsible for progesterone production after ovulation. A short luteal phase can lead to decreased progesterone levels.

    • Dysmenorrhea: Pain during menstruation, including cramps, nausea, and emotional variability.

    • All of these hormonal irregularities can lead to loss of progesterone and estrogen, resulting in bone degradation.

    Female Athlete Triad (Old)

    • Osteoporosis: Low bone density
    • Disordered Eating: Inadequate nutritional intake
    • Amenorrhea: Lack of menstruation

    RED-S: Relative Energy Deficiency in Sport (New)

    • This syndrome is caused by energy deficiency due to a mismatch between dietary intake and energy expenditure.
    • RED-S is now acknowledged in both males and females.
    • It is especially important for athletes in weight-based sports.
    • RED-S CAT is a concussion evaluation tool.

    The Pregnant Athlete

    • Competition is typically possible up to the 7th month of pregnancy.
    • Pregnant athletes often discontinue after the 3rd month of pregnancy.

    Biomechanical Changes in Pregnancy

    • Increased lordosis and upper spine extension.
    • Approximately 50% of pregnant individuals experience low back or pelvic girdle pain. 25% continue to feel pain after 1 year postpartum.

    Contraindications of Exercises During Pregnancy

    Menopause

    • Occurs between ages 40-60, on average age 52.
    • The ovaries start producing smaller amounts of hormones.

    Bone Health During Menopause

    • Decreased hormone production contributes to bone health degradation, increasing stress fractures and osteoporosis.

    Male Athlete

    Testosterone

    • Essential for fetal development.
    • Responsible for the development of primary and secondary sex characteristics.
    • Anabolic effects promote muscle growth and development.
    • Promotes and regulates spermatogenesis and maturation of sperm.

    Spermatogenesis

    • The process of generating spermatozoa.
    • Begins around age 13.
    • Occurs in the seminiferous tubules.
    • Testosterone is required for successful spermatogenesis.

    Penile Trauma

    Testicle Trauma

    • Hematocele: Swelling caused by blood collecting in the tunica vaginalis cavity. 50% of hematoceles involve testicular rupture, requiring surgical repair or aspiration.
    • Hydrocele: Swelling in the scrotum due to fluid accumulation in the thin sheath surrounding the testicle. Common in newborns and often resolves on its own. In adults and older boys, hydrocele may result from inflammation or injury.
    • Varicocele: Enlarged veins within the scrotum, similar to varicose veins. Can contribute to low sperm count or decreased sperm quality.
    • Spermatocele: Cystic swelling in the epididymis or testes containing spermatozoa.

    • Type IV: Fracture involving both the physis and metaphysis.
    • Type V: Crushing of the physis with no displacement, potentially causing premature closure.

    Testicular Torsion

    • A medical emergency.
    • The spermatic cord rotates and becomes twisted, cutting off blood supply.
    • Symptoms include swelling, nausea, abdominal pain, and one testicle appearing higher than the other.
    • Requires immediate medical attention, often requiring surgical correction.

    Youth Athletes

    • Young athletes are at risk for various injuries due to the unique features of their growing bodies, including:
      • Bone growth: Epiphyseal plates are weaker than surrounding ligaments and are prone to injury.
      • Mismatched growth: Bone growth outpaces soft tissue growth, leading to muscle-tendon tightness and increased susceptibility to overuse injuries.

    Common Problems in Youth Athletes

    • Epiphyseal Injuries:
      • Type I: Separation of the growth plate.
      • Type II: Fracture with small metaphyseal fragment.
      • Type III: Fracture within the growth plate.
      • Type IV: Fracture involving growth plate and metaphysis.
      • Type V: Crushing of the growth plate with no displacement.

    Female Athletes

    • Female athletes experience similar injury rates to males but have a higher risk of specific injuries.
    • Biomechanical Predisposition:
      • Increased Q-Angle: Creates valgus force on the medial structures of the knee (MCL, meniscus, ACL).
      • Smaller intercondylar notch: Can cause instability and hypermobility in the knee joint.
      • Quad-to-hamstring strength ratio: Imbalance increases stress on the ACL.
      • Hormonal effects: Estrogen and progesterone levels fluctuate during the menstrual cycle, which can affect collagen tissue and bone remodeling.
    • Skeletal Differences: Females have larger Q-angles, smaller intercondylar notches, and a greater susceptibility to ACL injuries compared to males.
    • Stress Fractures: Female athletes are prone to stress fractures due to overuse, poor mechanics, low bone density, hormonal factors, and societal pressures to maintain thinness.

    The Pregnant Athlete

    • Pregnant women can safely participate in exercise until the seventh month.
    • Biomechanical changes: Increased lordosis and upper spine extension can cause low back and pelvic girdle pain.

    • Musculoskeletal System: Decreased muscle mass and strength, increased collagen cross-linking.
    • Neurological Effects: Loss of brain weight and neurons, affecting balance and proprioceptive feedback.
    • Arthritis: Age-related degeneration of articular cartilage, causing pain and stiffness in weight-bearing joints.
      • Osteoarthritis: Most common, with bone-on-bone contact.
      • Inflammatory Arthritis, caused by the body's immune system attacking the joints.
      • Gout, characterized by crystals of uric acid forming in joints.

    Male Athletes

    • Testosterone: Hormone responsible for developing male secondary sex characteristics, promoting spermatogenesis.
    • Penile Trauma: Includes superficial wounds, contusions, lacerations, avulsions, frostbite, penetrating wounds, fractures, and priapism.
    • Testicle Trauma:
      • Hematocele: Accumulation of blood in the tunica vaginalis.
      • Hydrocele: Fluid accumulation in the scrotum.
