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 StudyThe effect of total knee arthroplasty on joint movement during functional activities and joint range of motion with particular regard to higher flexion users.
To evaluate active and functional knee excursion of patients before and after total knee arthroplasty (TKA) and to determine whether TKA restores quality of life related to functional activities of daily living. ⋯ Although TKA offers excellent pain relief and contributes to the overall well-being of the patient, these results suggest that it also leads to a reduced range of active and functional motion in the majority of patients. This is associated with a lower-than-normal physical quality of life. The design of implants and rehabilitation programmes should be reconsidered so that better range of motion and quality of life can be achieved for patients.

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.
