Failure rates of metal-on-metal hip resurfacings: analysis of data from the National Joint Registry for England and Wales Smith AJ, et al. Lancet. 2012 Oct 1. pii: S0140-6736(12)60989-1. doi: 10.1016/S0140-6736(12)60989-1. A total of 31,932 resurfacings were identified from the National Joint Registry for England and Wales. During the same period, 434,560 primary total hip replacements were performed. In women, resurfacing resulted in worse implant survival than conventional THR, regardless of head size. In men with smaller femoral heads, resurfacing resulted in poor implant survival. Thus, hip resurfacing resulted in similar implant survivorship to other surgical options in men with large femoral heads and inferior implant survivorship in other patients, particularly women. Meniscal and chondral injuries associated with pediatric anterior cruciate ligament tears: relationship of treatment time and patient-specific factors. Dumont, et al. Am J Sports Med. 2012 Sep;40(9):2128–33. Epub 2012 Jun 22. 408 patients under the age of 19 years underwent surgery for ACL reconstruction. 370 had a primary ACL reconstruction with required data for inclusion in the study. 208 were male and 162 female. 241 patients were treated less than 150 days from injury and 129 more than 150 days from injury. 160 had medial meniscal tears (43.2%), 209 had lateral meniscal tears (56.5%). Chondral injury was significantly associated with meniscal tear in the same compartment, being more common medially than laterally. Patients over 15 years had a higher rate of medial meniscal tear and weight above 65 kg was associated with a higher rate of meniscal tears. Medial meniscal tears were encountered at a higher rate when treated more than 150 days after injury and were independently associated with increased age and weight. Does carpal tunnel release provide long-term relief in patients with hemodialysis associated carpal tunnel syndrome? Kang HO, et al. CORR 2012 470, 2561–2565. The study group comprised 36 patients on hemodialysis with carpal tunnel syndrome (CTS) and 54 with idiopathic CTS treated by carpal tunnel release. The patients were matched by age, gender and symptom severity. In the short term, the hemodialysis group unlikeFailure rates of metal-on-metal hip resurfacings: analysis of data from the National Joint Registry for England and Wales Smith AJ, et al.
