Total Knee Arthroplasty in an Adult with Neglected Patellar Dislocation: A Case Report

Both operative and non-operative intervention can be utilized in the treatment of neglected patellar dislocation in adults. Operative interventionsinclude patellectomy, lateral retinacular release, medial retinacular augmentation using tendon transfer, and distal realignment. Neglected patellar dislocation has been rarely reported in adults. We report a case of neglected patellar dislocation with degenerative osteoarthritis in a 56-year-old male patient who underwent total knee arthroplasty combined with lateral retinacular release, medial retinacular augmentation, and anteromedial transfer of the tibial tubercle for distal realignment.

Deep Vein Thrombosis in May-Thurner Syndrome Patient after Operative Treatment of Acute Cauda Equina Syndrome: A Case Report / 대한척추외과학회지

May-Thurner syndrome, compression of the left common iliac vein by the right common iliac artery, or intimal hypertrophy of the vein resulting from chronic pulsatile force of the right common iliac artery, may results in deep vein thrombosis on the left lower extremity. A patient presented to our facility with deep vein thrombosis caused by May-Thurner syndrome, and showed post-operative fever, pain, and tenderness over the left leg, showing severe lumbar disc herniation with acute cauda equina syndrome. This syndrome should be considered as one of the causes of deep vein thrombosis in the left lower extremity.
