We analyzed treatment results of 34 (35 medial femoral condyles) patients divided
into 2 groups: Group I - 7 patients with juvenile OD (active growth), Group II - 28
adults with OD (no growth). At the time where surgery was performed, mean age of
Group I patients was 14-17, Group II - 18-34. Average history of symptoms before
surgery was 22 months for juvenile OD and 55 months for adult OD. Patients with
grade III and IV OD underwent deep arthroscopic transchondral tunneling of the
lesion (27); patients with intact joint surface (grade I and II) underwent retrograde
tunneling of lesion (8). Mean follow-up period was 6,8±0,8 years for juvenile OD and
8,0±0,7 years for adult OD. Clinical effect of treatment was evaluated on Hughstone
Scale and on the basis of standard biplanar X-ray images. Excellent clinical results
(6; 85,7%) were reported only in Group I patients with juvenile OD. In Group II (adult
OD), good results were reported in 22 (78,6%) cases, while in other 6 (21,4%) cases
it was satisfactory. Analysis of treatment results proved that differential approach to
the choice of subchondral bone perforation method produced excellent and good
long-term results in 87,5% of cases with grade I and II OD and in 77,8% of cases
with grade III and IV of this disease. In treatment of osteochondritis dissecans of
femoral condyles, stage- and age-dependent differential approach to the choice of
method of subchondral bone perforation in the lesion.
