Dr. Natasha Trentacosta is a pediatric and adult sports medicine trained orthopaedic surgeon based in the Los Angeles area. Her unique training allows her to care for athletes of all ages and levels of competition in the prevention and treatment of sports-related and traumatic injuries, utilizing non-operative treatment options such as physical therapy and regenerative medicine techniques as well

as operative interventions when indicated. Her surgical skills and individualized attention aim to help each patient return to the highest possible level of function in sports and life. After growing up in New York City, she attended Brown University with a concentration in Neuroscience. Returning to New York, the summer before entering medical school was spent at an internship at the Women’s Sports Medicine Center of the Hospital of Special Surgery. She went on to medical school at Albert Einstein College of Medicine and completed her residency in orthopaedic surgery at Montefiore Medical Center. She completed specialized training in adult sports medicine at Santa Monica Orthopaedic and Sports Medicine Group, providing sideline and training room medical coverage for local high schools and colleges, and assisting in the care of the LA Galaxy as well as Men’s and Women’s US National Soccer teams. With a strong passion for keeping children active and safe in sports and life, she went on to further training with international leaders in pediatric sports medicine at Boston Children’s Hospital, practicing surgical techniques that are unique to the treatment of the pediatric patient. Not only did she continue caring for local high school athletes, but also had the opportunity to cover the Boston Athletic Association road races, including the Finish line at the Boston Marathon. Returning to Los Angeles, she brings a passion for keeping children and adults active and returning them back to their full potential when injury strikes. Her research interests continue in the pediatric and female athlete, focusing on injuries of shoulder, elbow, hip, and knee.

Most injuries don't happen because an athlete got unlucky. They happen because the body wasn't ready for what the season demanded.⁠
⁠
The weeks before the season starts matter more than people realize. Strength, mobility, and conditioning built now are what protect knees, ankles, and shoulders once games and matches actually begin. Waiting until week one to "get in shape" is how so many of these injuries happen in the first place.⁠
⁠
If your athlete is gearing up for a new season, this is the time to build the foundation, not after the first practice.⁠

People ask me all the time why I did two fellowships instead of one.⁠
⁠
Here’s the real answer: I kept meeting patients who didn’t fit neatly into one box. A 14-year-old with the same ACL tear as the 45-year-old in my next room. A teenage gymnast whose growth plates changed the whole treatment plan.⁠
⁠
I didn’t want to send any of them somewhere else because they were the “wrong age” for my training.⁠
⁠
So I did the extra years. Pediatric and adult sports medicine, back to back. Harder training, but rare enough it’s worth it.⁠
⁠
Now I can treat an athlete from her first sprained ankle at 12 through the joint pain she’s dealing with at 50. No handoff.⁠

Access to sports is not a luxury for children. It is an important part of healthy development.⁠
⁠
When children participate in organized sports, they build strength, coordination, and physical literacy. They also learn how to communicate, manage frustration, work toward a goal, and develop confidence in their own abilities.⁠
⁠
A sports team also provides structure, mentorship, and belonging. A coach may become a trusted adult. A practice field may become one of the first places a child feels capable and connected to a community.⁠
⁠
But access is not equal. Registration fees, equipment costs, transportation, and the rising expense of competitive youth sports can exclude talented, motivated children before they ever get the chance to discover what they can do.⁠
⁠
That is why programs like LA City United FC matter. As part of the PLAYLA initiative, it helps create more equitable access to quality soccer training for young athletes across Los Angeles.⁠
⁠
Talent exists in every neighborhood. Opportunity does not.⁠
⁠
Every child deserves the chance to play, not only because sports can produce great athletes, but because they help build healthier, more confident, more resilient young people.⁠

Muscle loss doesn’t announce itself. It starts earlier than most people think, and by the time it’s noticeable, you’ve already lost ground on bone density, joint stability, balance, and metabolic health.⁠
⁠
The fix is simpler than people expect. Squat, hinge, push, pull, carry, that’s it. Two to three sessions a week is enough to start seeing real change, and you don’t need to start heavy. Just start.⁠ Progress along the way.⁠
⁠
Try picking one movement to add in your routine this week.⁠

Lifting heavy weights does not make you bulky. It makes you durable.⁠
⁠
Strength training builds the kind of resilience that protects your joints, improves your speed, and keeps you moving the way you want for decades. It will make groceries lighter, stairs easier, joints happier, and your body harder to break.⁠
⁠
Train for strength. Train for longevity. Train to keep doing the things you love. ⁠

Hi, I'm Dr. Natasha Trentacosta a board-certified orthopedic surgeon and sports medicine specialist, with dual fellowship training in adult and pediatric sports medicine.⁠
⁠
Rest days aren't a break from training; they're part of it. Muscle repair, tendon adaptation, and injury prevention all happen during recovery, not during the workout itself.⁠
⁠
The athletes I see get hurt most often aren't undertrained. They're under-recovered. Sleep, rest days, nutrition and listening to fatigue are just as much a part of performance as the training itself.⁠
⁠
What's one recovery habit you don't skip?⁠

Summer camp season keeps my office busy.⁠
⁠
Parents remember the sunscreen, water bottles, and extra socks. What is easier to miss is how quickly a growing body can become overloaded by back-to-back days of camp, practice, and little to no recovery.⁠
⁠
I see the same pattern every summer: overuse injuries and young athletes pushing through pain because they do not want to miss out.⁠
⁠
Most of these injuries are preventable—especially when parents know the early warning signs and give kids permission to rest before pain becomes an injury.⁠

The best part of this job isn't the surgery. It's the conversation that happens before it. Grateful for patients who trust me with both.⁠
