Case ReportsAcetabular augmentation using a second cup during revision hip arthroplasty: an unusual case report.
Acetabular wedge augmentation is a useful technique and is recommended in situations where cup revision is likely to be excessively difficult. Numerous augmentation designs that improve the stability of the hip are now available in the market. ⋯ We report our experience in treating such a case, using an augment cut from a second cup with a follow-up for 30 months. Though there is no substitute for proper preoperative planning, awareness of this procedure is helpful as unexpected problems do arise in revision acetabular surgery.

Comparative StudyImplications of the changing pattern of bacterial infections following total joint replacements.
To retrospectively review the causative organisms isolated from infected hip and knee replacements requiring revision. ⋯ This study found a definite increase in multiple-drug-resistant bacteria isolated from periprosthetic infections around total hip and knee prostheses.

Comparative StudyPost-thrombotic syndrome after total hip or knee arthroplasty: incidence in patients with asymptomatic deep venous thrombosis.
To measure the risk of developing signs of post-thrombotic syndrome 15 to 24 months after total hip or knee arthroplasty in patients with asymptomatic deep venous thrombosis (DVT). ⋯ Patients with above-knee DVT were much more likely to have post-thrombotic syndrome. Despite thromboprophylaxis with low-molecular-weight heparin, asymptomatic DVT is common after total joint arthroplasty and is responsible for the development of post-thrombotic venous insufficiency and post-thrombotic syndrome in a considerable proportion of patients. Once symptomatic or asymptomatic DVT is established, treatment appears incapable of preventing the occurrence of post-thrombotic syndrome, especially in cases of above-knee DVT. Efforts should hence concentrate on combating DVT propagation and improving DVT prevention.
