Physical Therapy for Valgus Knees in a 6 year old

Hello,
I have a 6 yr old patient with knocking knees and valgus. I tested his muscles and non of them are weak, spoke with his Orthopedist and was asked to treat him for a month and find out if therapy is working.
Now i have started giving him Angular traction for his Valgus and his Doctor has advised him to horse ride for his knocking knees, but upon discussing with senior therapists if i should advise a night-splint (KAFO) for continious traction, one of them agreed but the second did not.
if anyone of u could help and share a somewhat similar experiance it would be appreciated!
Thanks

Can you perhaps take a photo from the front,side and behind and upload it for us to see (You just add them as attachments when posting a message). This would give us a better basis on which to provide a comment :)

I will ask the guardians permission and get them ASAP!

Iam sorry guys ... the patient was a no show! I tried to contact the mother but her cell was off .. must have gone out of town!
