Types of OSD

After valuable research, I have realized that there are two types of people who get OSD.

1) Teenagers who are affected by growth spurts

2) Teenagers with weak quadriceps

Of course, both factors could be in play.

In the first category, the tibial tubercle has not fused with the tibial yet leading to pain and swelling.

In the second category, the weak quadriceps cause the pressure exerted to be transferred to the patella tendon. This is turn causes the tibial tubercle displacement.
