Abstract


ABSTRAK

Penyakit Osteochondral Lesion of the Talus (OLT) adalah kelainan pada tulang talus di lapisan subchondral yang berupa lesi osteochondral pada talar dome dengan konsekuensi abnormalitas pada tulang rawan sendi talar. Pasien biasanya datang berobat ke tenaga kesehatan dengan keluhan yang tidak spesifik dan dengan gejala seperti nyeri pada pergelangan kaki, bengkak serta berkurangnya berkurangnya ruang gerak. Penegakan diagnosis bisa dilakukan dengan anamnesis, pemeriksaan fisik dan pemeriksaan penunjang sederhana seperti foto X-ray maupun pemeriksaan penunjang canggih seperti CT-Scan dan MRI. Tatalaksana OLT bervariasi. Tatalaksana pada OLT tergantung dari tahapan lesi, kronisitasnya, dan keluhan simtomatis yang menyertainya. Pasien dengan keluhan simtomatis yang akut dan non-displaced sering diberikan terapi nonoperatif biasanya berupa terapi konservatif dengan imobilisasi. Lesi yang tidak berhasil atau tidak menunjukkan perbaikan dalam keluhan simtomatisnya setelah 3 sampai 6 bulan, serta lesi dengan displacement dapat direncanakan untuk terapi operatif. Ada beberapa macam tehnik operatif yang dapat dilakukan untuk menyembuhkan OLT. Tehnik operatif ini dapat dikategorikan menjadi cartilage repair, cartilage regeneration dan cartilage replacement techniques.

ABSTRACT

Osteochondral Lesion of the Talus (OLT) is an abnormality in the talus bone in the subchondral layer in the form of osteochondral lesions in the talar dome with consequent abnormalities in the talar joint cartilage. Patients usually come to a health care provider with nonspecific complaints and with symptoms such as pain in the ankles, swelling and reduced space for movement. The diagnosis can be made with a history, physical examination and simple investigations such as X-rays and sophisticated investigations such as CT-Scan and MRI. The management of OLT varies. The management of OLT depends on the stage of the lesion, its chronicity, and the accompanying symptomatic complaints. Patients with acute and non-displaced symptomatic complaints are often given nonoperative therapy usually in the form of conservative therapy with immobilization. Lesions that are unsuccessful or show no improvement in symptomatic complaints after 3 to 6 months, and lesions with displacement can be planned for operative therapy. There are several types of operative techniques that can be done to cure OLT. These operative techniques can be categorized into cartilage repair, cartilage regeneration and cartilage replacement techniques.
