I was diagnosed with OS as a 10 year old, ortho just said to let pain be my guide, take NSAIDs, ice, rest as needed but that I wouldn't cause further harm by pushing through. It never fully went away. I am now well into adulthood and still have a massive OS lump under my knee that causes pain from time to time. It's apparently uncommon but not unheard of for that to happen. I talked to a PT who specializes in treating gymnasts a few years ago and asked about the protocol I followed in childhood and he basically said the advice I received (from a sports ortho) was incorrect and that continuing to train with OS can indeed cause further harm. He said that often gymnasts with OS are experiencing rapid growth but also have various imbalances in muscles that need to be addressed (tight quads are super common in kids with OS), thus the need for PT. I would look into meeting with an ortho who specializes in treating youth athletes specifically and also possibly consider PT. And make sure the protocols are being followed by gymnast and coaches- be specific! It's annoying (for kid & coach) but it's so much better to be patient than keep pushing through and risking something worse.
Totally agree with finding an ortho theat specializes in young athletes and looking into PT.
Lol, I was diagnosed with something similar to OS when I was 8 (although I may have mis-diagnosed since chondromalacia patella usually affects adults whose growth plates had already fused). My ortho's orders was really harsh:
1. No running
2. No sports
3. No gaining weight
4. Do a set of knee exercises that he gave me 3x a day.
I asked how long I had to follow the orders ... I was young ... I asked "How long do I gotta do all of this for?"
He told me FOREVER ... and IF I followed his orders, I wouldn't need a new knee until I was 40 years old.
No clue how I was supposed to follow #3 without breaking #1 and / or #2, lol. I was in 2nd grade. How was I supposed to grow up without gaining weight???
I tried my best to follow directions (but I was a hyperactive child, lol). I was barred from going to recess because I might run or play kickball. In gym class, I was allowed to do (most of) the exercises, but when they played the fun game, I had to do my knee exercises.
The diagnosis was in early November (because I didn't tell my parents my knee hurt until AFTER football season was over).
I made it to Christmas break following the orders (for the most part ... he never said no skipping and no cartwheels, lol). While home on Christmas break, my parents eventually sent me outside to play because I was bouncing off the walls. The first day back to school, my dad came and told my teacher to forget the doctor's orders. He may have (he can't remember) even gone to the office and torn up the order. I was basically going to just let pain be my guide. I am now 48 years old, weigh more than I did in 2nd grade, and still have both of my original knees - I am just lacking cartilage.
