We treated 17 knees in 15 patients with severe ligament derangement and dislocation by open repair and reconstruction. We assessed the competence of all structures thought to be important for stability by clinical examination, MRI interpretation, and surgery. Our findings showed that in these polytrauma patients clinical examination was not an accurate predictor of the extent or site of soft-ti...

Congenital lateral dislocation of the patella is a rare condition caused by displacement of the extensor mechanism of the knee, which occurs before or shortly after birth (Malkin 1932). The patella is small and cannot be replaced in its normal position except by operation. This type of dislocation differs from recurrent or habitual dislocation of the patella, which occurs during childhood or ad...

BACKGROUND Congenital dislocation of the knee (CDK) is a very rare condition that comprises a spectrum of deformities from subluxation to complete dislocation. The incidence of CDK is estimated at 1 per 100,000 live births, which is 1% of the incidence of developmental dysplasia of the hip (DDH). Moreover, 40-100% of patients with CDK have additional musculoskeletal anomalies, the most common b...

INTRODUCTION Reduced intrauterine space gives rise to 'packaging disorder' which may involve joint dislocations or contractures. We present an unique case where mutiple joints were dislocated involving left congenital knee dislocation (CDK), bilateral congenital hip dislocation (CDH) and congenital talipes equino varus (CTEV)deformities. CASE REPORT A preterm baby boy born to mother with diag...

PURPOSE To analyze the causes and types of complications after unicompartmental knee arthroplasty (UKA) and determine proper prevention and treatment methods. MATERIALS AND METHODS A total of 1,576 UKAs were performed for osteoarthritis of the knee from January 2002 to December 2014 at one institution. We analyzed complications after UKA retrospectively and investigated proper methods of trea...

Chronic patellar dislocation is a rare condition where the patella remains dislocated throughout knee range of motion during flexion and extension. In adults, the delayed presentation of this condition is often due to symptoms caused by the onset of severe secondary osteoarthritis. To the authors' knowledge, all of the cases reported in the literature have been treated by patellofemoral or tota...
