Actionable Insights

1. Strengthen Gluteus Medius/Minimus

Prioritize strengthening the gluteus medius and minimus (hip abductors) from an early age, as these muscles are crucial for preventing numerous lower extremity injuries, including hip fractures and ACL tears, and their strength will naturally degenerate over time.

2. Avoid Inactivity for Cartilage

Engage in appropriate activity to maintain cartilage health, as inactivity is detrimental and significantly depresses the cartilage matrix content.

3. Maintain Good Mechanical Alignment

Strive to maintain good mechanical alignment of the lower extremity, where a plumb line from the hip to the ankle passes through the center of the knee, as misalignment significantly increases the risk of knee degeneration.

4. Lose Weight for Knee Health

Losing even a small amount of weight, such as five pounds, can significantly reduce the load on your knees (e.g., seven times body weight when squatting), potentially delaying or eliminating the need for knee replacement surgery.

5. Engage in Neuromuscular Training

Prioritize neuromuscular training to improve coordination and proprioception, helping to prevent lower extremity injuries by enhancing the body’s ability to react dynamically and recover from unexpected movements.

6. Improve Hip Flexor Flexibility

Actively work on hip flexor flexibility, especially if you sit frequently, as tightness in this muscle group can create imbalances affecting antagonistic muscles like the gluteus maximus and hamstrings.

7. Incorporate Daily Jumping/Plyometrics

Integrate a daily jumping routine, such as jumping rope, into your warm-up to maintain elasticity in the lower body and improve neuromuscular control, which can help prevent injuries.

8. Early Hip Dysplasia Screening

Ensure pediatricians perform thorough hip exams on newborns and consider requesting an ultrasound for better quantification, especially if there are risk factors like breech birth, as early intervention with a brace can prevent future arthritis.

9. Rapid Mobilization Post-Hip Fracture

For elderly patients with hip fractures, immediate surgical intervention and rapid mobilization are critical, as non-operative treatment is a ‘death sentence’ and hospitalization alone can be catastrophic, leading to a 15-30% one-year mortality rate.

10. Optimize Pre-Surgery for Hip Fracture

Implement a team approach, including geriatric specialists, to medically optimize elderly hip fracture patients before surgery, ideally within 48 hours, to ensure they can safely undergo the procedure and improve outcomes.

11. Groin Pain: Stop Running

If an endurance athlete experiences groin pain, immediately stop running and seek medical evaluation to rule out a femoral neck stress fracture, which can have severe consequences if untreated.

12. Surgery for Tension Stress Fracture

Tension-sided femoral neck stress fractures often require surgical pinning to prevent displacement and severe complications like avascular necrosis, leading to a quicker recovery compared to prolonged non-weight-bearing.

13. Rest for Compression Stress Fracture

For compression-sided femoral neck stress fractures, use crutches until pain-free with weight-bearing, then gradually reintroduce exercises and physical therapy over six to eight weeks for healing.

14. Fluoroquinolones: Stop if Pain

If taking fluoroquinolone antibiotics (e.g., Cipro, Levoquin) and experiencing any pain, immediately stop activity and rest, as these medications can increase the risk of Achilles tendon rupture, sometimes even after a single dose.

15. Address Energy Deficiency for Healing

If experiencing recurrent stress fractures or poor healing, investigate potential relative energy deficiency (e.g., female athlete triad), consulting an endocrinologist and checking vitamin D levels, as undernourishment can severely impair bone health.

16. Avoid Contact Sports Post-Replacement

After total hip or knee replacement, avoid contact sports due to the high risk of catastrophic injury (e.g., stress risers above implants), though activities like skiing or tennis may be permissible depending on individual recovery and risk tolerance.

17. Beware ‘Stem Cell Therapy’ Claims

Be highly skeptical of clinics offering ‘stem cell therapy’ for orthopedic issues, as currently, no such therapies are approved by the FDA in the United States for these conditions, and claims of pluripotent cells becoming new cartilage or tendon are not supported.

18. Choose Surgeon Who Listens

When choosing a surgeon, prioritize someone who actively listens, makes eye contact, and does not rush you, as good rapport and communication are crucial for effective care.

19. Inquire Surgeon’s Specific Outcomes

When considering surgery, ask your surgeon for their personal complication rates (e.g., wound infection, reoperation, persistent pain) and their plan for troubleshooting if expected outcomes are not met, as this reflects their competence and ability to manage potential issues.

20. Ask About Surgery Alternatives

Always ask your surgeon about alternatives to surgery and why a surgical approach is recommended over non-operative options; a non-defensive, clear explanation indicates a good surgeon.

21. Plan for Conservative Treatment Failure

Always ensure your doctor outlines a clear plan for what to do if conservative treatments (e.g., physical therapy for an ankle sprain) do not yield improvement within a specified timeframe, as this indicates a thorough approach to your care.

22. Biologics are Symptom Modifying

Understand that current orthopedic biologics (like PRP) primarily act as symptom-modifying treatments, reducing pain rather than regenerating tissue, which can be valuable given the limited effective non-surgical options for conditions like arthritis.

23. PRP for Knee Arthritis

Platelet-rich plasma (PRP) therapy shows promising data as a symptom-modifying treatment for knee arthritis, potentially more effective than cortisone over a year, making it a worthwhile option to explore with a physician.

24. Combine HA and PRP for Knee Arthritis

Consider a combined injection of hyaluronic acid (HA) and platelet-rich plasma (PRP) for knee arthritis, as studies suggest this combination may be more effective at reducing symptoms than either treatment alone.

25. PRP for Tennis Elbow

Platelet-rich plasma (PRP) therapy shows good evidence of efficacy for treating tennis elbow, making it a viable treatment option to discuss with a physician.

26. PRP for Gluteus Medius Tears

Platelet-rich plasma (PRP) therapy appears to work ‘pretty decently’ for gluteus medius tears, offering a potential treatment option.

27. Thorough Diagnosis for Heel Pain

If experiencing heel pain, seek a comprehensive, step-by-step diagnostic approach from a physician, as causes can range from plantar fasciitis and stress fractures to nerve compression or even referred pain from a disc herniation.

28. Prehab Before ACL Reconstruction

Undertake prehabilitation (prehab) before ACL reconstruction surgery to prepare the body, understand long-term implications, and reduce the risk of re-injury, ensuring a smoother recovery process.

29. Quiet Knee Before ACL Surgery

If undergoing ACL reconstruction, consider waiting until the initial inflammation has subsided and the knee is ‘quiet’ (feeling almost normal) before surgery, as this can lead to a better surgical experience.

30. Patellar Tendon Graft for ACL

For young, highly active individuals participating in high-risk sports, the patellar tendon graft is considered the ‘gold standard’ for ACL reconstruction due to its superior strength and lower re-rupture risk, despite a potentially harder early recovery and kneeling pain.

31. Hamstring Graft for Kneeling/Yoga

If you frequently kneel, garden, or practice yoga, discuss using a hamstring tendon graft for ACL reconstruction, as it avoids the kneeling pain associated with patellar tendon grafts, allowing for a more tailored recovery.

32. Allograft for Older, Less Active

If you are over 34 and participate in lower-risk recreational activities (e.g., hiking, not high-level sports), an allograft for ACL reconstruction may be a reasonable option due to easier initial recovery, despite a higher re-rupture risk compared to autografts.

33. Strengthen Quads for Knee Pain

For patellofemoral syndrome (anterior knee pain), engage in quadriceps strengthening exercises, often through physical therapy, to improve kneecap gliding and reduce symptoms.

34. BFR for Quad Strengthening

Consider using blood flow restriction (BFR) training for quadriceps strengthening, especially when higher loads are painful or contraindicated, as it can achieve similar muscle benefits with lower mechanical stress.

35. Conservative Ankle Sprain Treatment

For most ankle sprains, conservative treatment, including strengthening the peroneal muscles, is the initial approach, as the majority of individuals will recover without surgery.

36. MRI for Persistent Ankle Pain

If an ankle sprain is not recovering after conservative treatment, seek an MRI to assess for potential cartilage or bone injury, which may require further intervention.

37. Bunion Surgery for Pain Only

Only consider bunion surgery if the condition causes significant pain or crowds out other toes, as the recovery can be difficult, and it’s not recommended if you are comfortable in your shoes and pain-free.

38. Maintain Calf Flexibility

Ensure good flexibility in both the gastrocnemius and soleus muscles to help prevent Achilles tendon issues and other lower extremity problems.
