Naturally occurring high-Mr hyaluronan, bound to the surface of nanoliposomes (denoted targeted hyaluronan liposomes, or tHA-LIP), is a candidate for active targeting to tumors, many of which overexpress the hyaluronan receptors CD44 and RHAMM. The surface-bound hyaluronan also provides a hydrophilic coat that, similar to polyethylene glycol, may promote long-term circulation. We recently repor...

OBJECTIVE To assess the incidence of total hip arthroplasty (THA) in osteoarthritic patients who were treated by arthroscopic debridement and to evaluate factors that might influence the time interval from the first hip arthroscopy to THA. DESIGN Retrospective clinical series METHODS Follow-up data and surgical reports were retrieved from 564 records of osteoarthritic patients that have had...

In the title compound, C(6)H(6)N(2)O(3)·C(8)H(8)O(4), the 2-amino-4-nitro-phenol (ANP) and 1-(2,4,6-trihy-droxy-phen-yl)ethanone (THA) mol-ecules are both nearly planar, with r.m.s. deviations of 0.0630 and 0.0313 Å, respectively. The angle between the least-squares planes of THA and ANP is 48.99 (2)°. In THA, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, ...

Metal-on-metal (MOM) hip articulations represent a potential alternative to conventional metal-on-polyethylene total hip arthroplasty (THA). We performed a systematic review of the peer-reviewed literature in search of studies comparing MOM with conventional primary THA with regard to functional outcomes, radiographic outcomes, and complication rates. Four Level I randomized controlled trials r...

We surveyed 343 young women with 420 total hip arthroplasties (THAs) regarding pregnancy and childbirth after THA. The mean age at surgery was 35 years (18 to 45). The mean length of follow-up after the initial arthroplasty was 16 years (6 to 27). Of these 343 women, 47 (13.7%) had a successful pregnancy after their primary THA. The first baby after a THA was delivered vaginally in 30 patients ...

BACKGROUND The aims of this study were to assess patients' preoperative expectations of the outcome of total hip or knee arthroplasty (THA/TKA) regarding specific aspects of functioning and to determine to what extent each expectation was fulfilled after 1 year. METHODS This was a prospective cohort study. Preoperative expectations and their fulfillment after 1 year were measured with the Hos...
