Dislocation of the knee is a serious injury which can have long-term adverse effects which may impair the patient’s return to physical employment and recreational activity. Vascular disruption and injury to the common peroneal nerve are not unusual and will ...

This month we highlight developmental dysplasia of the hip. The entity is one known since the beginning of recorded history, although until relatively recently it was known in the English language as congenital dislocation of the hip. Our Classic this month reproduces an article published in 1891 by AM Phelps describing a patient with an unusual congenital anterior dislocation of the hip and al...

Because of demographic changes, ever greater demands are made of knee replacement systems by patients and surgeons. To meet these demands, knee joint systems with increased flexion are currently being marketed. The main hypothesis of the present study was to evaluate the functional outcome of a high flexion TKA in amid-term follow up. 75 consecutive patients (29 men and 46 women) who had primar...

Atlanto-axial dislocation IS an uncommon condition. It is usually secondary to trauma, infection (tuberculous and non-tuberculous atlas and axis) and rheumatoid arthritis. Other uncommon causes reported include retropharyngeal abscess, malignant deposits, ankylosing spondylitis (Sorin, et al, 1979). Congenital atlanto-axial dislocation is rare. Wadia (1967) first drew attention to its relative ...

Superior patellar dislocation is a very rare pathology, which happens in middle age. We report a case of spontaneous superior patellar dislocation, which occurred at 30 years of age. Differential diagnosis is patellar tendon rupture, which could be reliably excluded by clinical examination and radiographs. Reduction manoeuvres should be tried with diluted intra-articular local anaesthetic for h...

Acute traumatic patellar dislocation is a common injury in the active and young adult populations. MRI of the knee is recommended in all patients who present with acute patellar dislocation. Numerous operative and non-operative methods have been described to treat the injuries; however, the ideal management of the acute traumatic patellar dislocation in young adults is still in debate. This art...

Congenital proximal radioulnar synostosis (PRUS) is a rare congenital anomaly where the radius and ulna are fused at the proximal portion which can cause the rotation of the forearm to be restricted (Fig.1). Bilateral pronation ankylosis over sixty degrees can restrict the patient’s daily activities. According to the position of the radius head in x-ray, PRUS is classified into three types, pos...

Purpose The purpose of this study was to evaluate the efficacy of unicompartmental knee arthroplasty (UKA) in young active Asian patients by analyzing clinical outcomes, complications and survival rates. Materials and Methods Eighty-two knees were evaluated with a minimum follow-up of 5 years after Oxford phase 3 UKA in patients less than 60 years of age at the time of surgery. Their mean age...
