Ball and Socket, Pivot, and Gliding: Keeping Your Female Hinges Healthy Joanna Wilson, D.O. HerCare at ADC
Famously Bad Posture
High Heels and Posture
Posture To Prevent Muscle Spasms
Sources of Joint Pain Muscle Ligaments Cartilage Tendon Bursa Bone Fascia
Cartilage No blood supply Oxygen and nutrient delivery and waste removal is done by compression Made up of four substances: collagen, proteoglycans, water, and chondrocytes:
Cartilage Collagen: Key component of cartilage; provides cartilage with its strength; creates a framework that houses the other components of cartilage Proteoglycans: Combination of protein and sugar, which trap water in cartilage; woven around and through collagen, allowing cartilage to change shape when compressed Water: Healthy cartilage contains more than 70% water; shock absorber and lubricates and nourishes the cartilage. Chondrocytes: Cells produce new collagen and proteoglycans in cartilage; release enzymes which help break down and dispose of aging collagen and proteoglycans
Sex Differences in Cartilage Cartilage thickness and volume are greater in boys and men vs girls and women Women lose cartilage from their tibia (the larger bone between the knee and ankle) at 4x the rate of men, and they lose cartilage from the kneecap at 3x the rate Greater cartilage loss in women than in men began at age 40 and increased with age
Osteoarthritis Has Active Inflammation
Osteoarthritis Risk Factors Excessive loading High BMI Previous knee injury Age Genetics Sex
Female vs Male Hips
Osteoarthritis Risk: Overweight Goal BMI is <25 to reduce OA in the population by up to 53%
Obesity-related pathways Accumulation of fat in muscle which reduces muscle mass and strength Instability of joint Reduced impact absorption at joint by muscles Altered gait patterns Misalignment of joint
Osteoarthritis Risk: Excessive Loading Kneeling, squatting Pes Planus, Pronation of foot, Q-angle Land and turn movements
Osteoarthritis: Previous Knee Injury Ligament tears, meniscal injuries, and fractures involving the articular surface
Anterior Cruciate Ligament (ACL) Injuries up to 10x more common in women – Relatively smaller diameter, relative hamstring weakness, sex hormone variations Due to deceleration with landing and pivoting – 5%/year risk at collegiate level in volleyball, basketball, and soccer Can cause chronic instability and osteoarthritis later
Joint Changes and Hormones Increased laxity during ovulatory and luteal phases Increased collagen turnover during follicular phase Highest likelihood of ACL injuries during menses Variations of hormone levels and receptors in target tissues during peri and post menopause – Hormone blockers and hormone replacement affect joint pain
Prevention of ACL Injuries ACL –tear prevention programs: Proprioceptive and neuromuscular training programs Awareness of reduced joint position sense during menses
Anterior Knee Pain (Patellofemoral Pain) Twice as common in women Due to: – Relative weakness of quadricep – Delayed firing of vastus medialis obliqus – Increased q angle
Treatment of Patellar Syndrome PT: strengthen medial thigh muscles and hip external rotators, strengthen quadriceps Taping of patella Arch supports
Bursitis Inflammation of the sac filled with lubricating fluid which separates joint structures
Common Bursitis Locations
Sprain Inflamed ligament
Tendonitis Tendon connects to bone and behaves as an elastic strip Inflammation can occur
Enthesopathy Inflammation where a ligament or tendon attaches to a bone causes calcium deposits Spurs develop
Challenges in Supplement Research Content variability (amount, quality) Judging endpoints Quality of study Number of participants
Nutritional Recommendations Fruits and vegetables for antioxidants (esp Vitamin C) High calcium diet for bone strength and muscle function Vitamin D for bone strength and balance High quality protein for muscle strength
Exercise To Promote Joint Health Allow compressive movement of cartilage Increase bone strength Tightens and thickens ligaments Secure joint tracking with strong, balanced muscle traction
Hamstring Curl Stand with the front of your thighs against a surface (a table or wall). Flex one knee up as far as is comfortable. Hold for seconds, then lower slowly. If possible, do not touch the floor between repetitions. (Ankle weights will increase the intensity.) Do 1-3 sets with repetitions each. Remember to rest in between sets.
Bent-Leg Raises Sitting in a chair, straighten one leg in the air (without locking the knee). Hold for about one minute. Bend your knee to lower the leg about halfway to the floor. Hold for 30 seconds. Return to starting position. Work up to 4 reps on each leg.
Abductor Raise Lie on your side, propped on one elbow. The leg on the floor bent, the other straight. Slowly lift the top leg, hold for seconds, then lower. (Ankle weights will increase the intensity). Do 1-3 sets with repetitions each. Remember to rest in between sets.
Step-Ups Stand in front of a step, like a sturdy bench or stairs, about two feet high (or less if necessary). Step up onto the support, straighten your knees fully (without locking them) and step down. Maintain a steady pace. If you are comfortable with your balance, pump your arms while doing this exercise. Start with 1 minute, slowly building your time.exercise
Wall Slide Leaning with your back against a wall, bend your knees 30°, sliding down the wall, then straighten up again. Move slowly and smoothly, using your hands on the wall for balance. Keep feet and legs parallel, and do not allow knees to go out over the toes. Repeat times.
Stationary Bike Biking is a good way to increase strength and range of motion. Make sure you have the right positioning of the legs. At the bottom of the pedal stroke, the bend in the knee should be 15 degrees. Start with 10 minutes and slowly increase your time.
Sex-Differences in Running Recreational, habitual exercise was not associated with knee osteoarthritis Elite female runners were more likely than male to develop knee OA Some studies report a higher risk of hip osteoarthritis in men with high or moderate levels of physical activity
The Best: Water Aerobics
Starting Exercise Increase intensity and novel movements with caution Cross train Low-impact repetition is best Listen to your joints Improve range of motion, flexibility, and balance
To Wrap It Up… Avoiding obesity and maintaining good posture limits joint dysfunction Topical and oral supplements may be helpful, but quality studies do not exist to confirm benefit Varying your daily low-impact exercise puts healthy stress on your joints
