Background:
Treatment of symptomatic osteochondral lesions(OCL) of the
talus is challenging. Different treatment modalities exist. Little is known about
long term outcome after Osteochondral Autograft transfer system (OATS)
Purpose / Aim of Study:
Retrospective long term follow up after OATS in the
talus
Materials and Methods:
Twentynine patients (30 feet) were operated with
OATS in the talus at the Hessingpark-Clinic 2004-2009. 15 patients (16 feet)
were available for follow up and clinical control. All patients had been followed
regularly with MRI and AOFAS score pre- and post operatively. 10 patients were
available for a new MRI. Health related quality of life (HRQL) was assessed by
using the SF-36 questionnaire for all patients.
Findings / Results:
Clinical and radiological follow up time 7,95 ( 5,9-11,6)
and 7,69 (5,9-11,2) years. Average patient age 47,2 years (18,6-69,3). OATS
donor site: Femur condyle 13, anterior Talus 3. Fourteen medial, 2 lateral OCL
lesions. OCL lesion size: average 132 (49-242) mm2. Average AOFAS score
preoperatively 62, 1 year postoperatively 71,0 and 8 years post operatively
86,3. Magnetic resonance of cartilage repair tissue (Mocart) score 3 mths post
op 82,3 and 8 years post op 52,3. The physical component summary score
(PCS) of SF-36 showed no significant difference compared to Danish norm
population using one sample T-test, same age. (87,33 and 87,69) No corre-
lation between cystic lesions in the OATS and AOFAS scores. No radiological
breakdown of OATS. No reoperations. One patient had pesistent knee pain after
OATS.
Conclusions:
Long term clinical evaluation of OATS in the talus indicates a high
patient satisfaction and a radiologically good long term integration and qual-
ity of the Osteochondral cylinders. No correlation between AOFAS score and
Mocart score. Knee pain can be a persistent problem for patients after OATS.
