Femoroacetabular Impingement

Explanation of Diagnosis

Femoroacetabular impingement (FAI) means the hip bones and joint surfaces do not move smoothly with certain hip positions. This can happen when there is extra bone shape on the femur (ball) and/or acetabulum (socket), which can cause the joint to “pinch” during bending, twisting, or reaching your hip into a flexed position. Over time, that repeated pinching can irritate the labrum and joint lining, leading to pain and stiffness. Common symptoms include groin pain, pain with sitting or getting in/out of a car, a catching or clicking sensation, and reduced hip motion.

Specific Work Modifications

• Change your workstation so you can avoid long periods of deep hip bending; try a chair that keeps your hips level with or slightly above your knees.
• Take position breaks every 30 to 45 minutes to stand, walk briefly, and let your hip reset to a more neutral angle.
• Limit activities that require repeated squatting, kneeling, or climbing stairs while holding loads close to your body.
• When you must sit, keep your knees from pulling far up toward your chest and avoid crossing your legs on the affected side.
• If you work at a desk, use a footrest or switch between sitting and standing every 30 to 60 minutes.
• If you use a vehicle for work, adjust the seat so you are not forced into deep hip flexion for long drives.

Specific Activity Modifications

• Avoid sports or drills that repeatedly load the hip in deep flexion, such as deep squats, lunges, hill sprints, and cutting/pivoting.
• Temporarily reduce running, jumping, or high-impact workouts if they trigger groin pain or catching.
• Choose lower-irritation options like level walking, stationary cycling with low resistance, or swimming with a neutral hip position.
• Use shorter strides and a more upright posture during walking or treadmill use to reduce hip pinch positions.
• During stretching, stop well before you feel sharp pinching in the groin; aim for gentle tension only.
• If you notice “catching” during a specific motion (such as getting out of a chair), modify the technique and reduce range until symptoms calm.

Recommended Supplements

• Omega-3 fish oil, about 1,000 mg per day of combined EPA/DHA, may help support overall inflammation balance.
• Vitamin D3, commonly 1,000 to 2,000 IU daily, can be helpful if your level is low for bone and muscle support.
• Curcumin (turmeric extract), commonly 500 to 1,000 mg once or twice daily, may help some people with joint comfort.
• Glucosamine sulfate, commonly 1,500 mg daily, may support cartilage-related symptoms in some individuals.

Recommended Nutrition and Hydration

Diet Recommendations

• Aim for a Mediterranean-style pattern with vegetables, fruit, beans, whole grains, olive oil, nuts, and lean proteins.
• Include omega-3-rich foods such as salmon, sardines, chia, or ground flax a few times per week if you can.
• Choose high-fiber foods and adequate protein at each meal to support tissue repair and muscle strength.
• Limit excess added sugars and highly processed foods, especially if you notice flare-ups after them.

Hydration Tips

• Drink regularly through the day so your urine is typically light yellow, especially if you’re exercising or in heat.
• If you sweat a lot, include electrolytes via foods (soups, fruits, yogurt) or an electrolyte drink as needed rather than relying on water only.

Home Exercise Prescription

Perform these exercises about 4 to 5 days per week, with gentle effort and no sharp pinching.

1. Supine glute bridge: Lie on your back with knees bent; tighten your glutes and lift your hips until your shoulders to knees form a mostly straight line; hold briefly, then lower slowly; do 2 sets of 8 to 12 reps.
2. Clamshells: Lie on your side with knees bent and feet together; keep your pelvis stable and slowly open the top knee without pain; pause, then return; do 2 sets of 10 to 15 reps per side.
3. Side-lying hip abduction: Lie on your side and lift the top leg slightly upward (toes pointing forward) without twisting your hip; control the lowering; do 2 sets of 8 to 12 reps per side.
4. Gentle hip flexor stretch (pain-free): Stand near a wall or use a chair for balance; step one leg back and tuck the pelvis slightly (glutes gently tightened) until you feel mild front-of-hip stretch; keep it below any pinching level; hold 30 to 45 seconds per side, 2 rounds.
5. Figure-4 glute stretch: Lie on your back, cross the ankle of one leg over the opposite knee, then gently pull the uncrossed thigh toward you until you feel a mild stretch in the buttock; do 2 rounds of 20 to 30 seconds per side.
6. If any exercise reproduces sharp groin pinching, catching that worsens, or sudden increase in pain, stop that movement and scale back the range.
