Retrospective 36 hips
Comparing DI with arthroscopy findings in juvenile dogs underoing DPO

Low positive correlation bwt synovitis and DI

Question 2

Jenkins VS 2020

retrospective

22 DPO 4 did not

Answer 2

F/U rads 49m later: most hips BVA<10 after DPO
50% of nonsx group BVA>10

Laxity index >1 not contraindication

DPO prevented radiographic OA in med-long term

Question 3

Jenkins VCOT 2023

kinetic and rads of unilateral DPOs in 6 dogs

Answer 3

Untreated hips increased BVA scores, treated reduced scores - not sig result

DPO hips had total pressure index and lameness scores similar to normal hips
