Randomized controlled trial of supervised physiotherapy versus a home exercise program after hydrodilatation for the management of primary frozen shoulder.

Hypothesis And Background: Hydrodilatation and physiotherapy are commonly used treatments for primary frozen shoulder. Little is known about the optimal form of physiotherapy. This study reports a randomized controlled trial comparing 2 forms of physiotherapy after hydrodilatation.

Polymerase chain reaction can detect bacterial DNA in aseptically loose total hip arthroplasties.

Identifying low-grade infection in failed total hip arthroplasties is an important but difficult task. This study investigated the ability of the polymerase chain reaction to identify low-grade infection during revision of total hip arthroplasties that failed from aseptic causes. One hundred thirteen specimens from 31 total hip arthroplasties revised for aseptic loosening were compared with 105 control specimens from 28 primary total hip arthroplasties.

Contamination of primary total hip replacements in standard and ultra-clean operating theaters detected by the polymerase chain reaction.

Background: Many organisms that are responsible for low-grade infection after total hip replacement (THR) are not recognized by routine culture.

Patients And Methods: We examined wound contamination during primary total hip replacement performed in standard and ultra-clean operating theaters. 20 THRs were performed in each type of theater.
