Bilateral Patella Dislocation after Total Knee Arthroplasty: A Report of Two Cases and a Review of the Literature

Total Knee Arthroplasty in Severe Unstable Knee: Case-Report and Literature Review

  Multiplanar or global laxity in arthritic knee is rare , most of this patients have neuromuscular disorder (post poliomyelitis , spinal dystrophy) or history of knee trauma. Ligament insufficiency and severe bone loss is significant in this patient. The estimated prevalence for the concurrence of charcot marie-tooth (CMT) with myasthenia gravis (MG) suggests an extremely rare event. We have p...

Does a Previous High Tibial Osteotomy (HTO) Influence the Long-term Function or Survival of a Total Knee Arthroplasty (TKA)?

 High tibial osteotomy (HTO) is a well established technique for the treatment of medial osteoarthritis ofthe knee with varus malalignment. The outcome of total knee arthroplasty (TKA) after HTO remains uncertain.The aim of this paper is to revise the literature with the aim of answering the following question: Does a previous (HTO)influence the long-term function or survival of a TKA?. The sea...

Giant cell tumor of patella: A case report and review of literature

Objective: Patella is a sesamoid bone which develops in the quadriceps tendon. It is an uncommon site for neoplasms. The most common primary tumors which involve patella are benign. These include chondroblastoma, giant cell tumor (GCT) and aneurysmal bone cyst. Malignant lesions are less common in patella. These encompass metastasis, osteosarcoma and hemangioendothelioma. The most common compla...

Medial patellofemoral ligament reconstruction for patellar dislocation due to rupture of the medial structures after total knee arthroplasty: a case report and review of the literature.

Patellar dislocation is a well-recognized major complication after total knee arthroplasty (TKA). Treatment of this injury is determined according to the cause of the dislocation. In particular, proximal realignment, distal realignment, and lateral retinaculum release are options if patellar instability is not caused by prosthetic malposition. Here we report a case of patellar dislocation follo...
