Initial conservative treatment of osteochondral fracture of the patella following first-time patellar dislocation Whereas, some of the patients with large OCFs (five patients with OCFs of the inferomedial facet involving central ridge) had finally failed of conservative treatment due to recurrent patellar dislocation episodes during conservative treatment protocol. OCD usually causes pain during and after sports. Osteochondral fracture When the five patients with the large OCFs involving the central ridge were included in the outcome analysis of redislocation rate (all of the five patients were regarded as redislocation cases of group 1), the intergroup difference of redislocation rate was also insignificant (p = 0.108).

Lee BJ, Christino MA, Daniels AH, Hulstyn MJ, Eberson CP. Lastly, there was demographic difference in limb alignment between groups 1 and 2, but it is unclear what effect this would have on successful nonoperative management.
