Heterotopic bone formation after posterior cruciate ligament reconstruction using inlay method and posterolateral corner sling with tibia tunnel: report of one case.
We describe one case of posterolateral capsular heterotopic ossification (HO) which needed surgical excision after posterior cruciate ligament (PCL) reconstruction with modified inlay method and posterolateral corner sling with tibia tunnel. She had blunt proximal tibial direct trauma 6 months ago and there were no reports of limb ischemia or a pulse deficit before she was seen at our outpatient clinic. There was neither other site trauma history. Clinical examination and MRI results were consistent with tear of the PCL, posterolateral corner injury showing posterolateral rotatory instability and incomplete peroneal nerve injury which recovered completely. As above mentioned, we operated and she showed range of motion of 0-30 degrees at postoperative 4 months. There was no specific finding on X-ray and we have done arthroscopic adhesiolysis and gained range of motion of 0-120 degrees . But, after 6 months later from initial operation, she showed ankylosis and HO was seen at posterior aspect and we removed it surgically at postoperative 12 months. After that operation, there was no recurrence and she showed range of motion of 0-140 degrees at postoperative 42 months.
