Prevention of pseudo-patella baja during total knee arthroplasty.

Purpose: Pseudo-patella baja (PPB) is a surgical complication that can arise from total knee arthroplasty and occurs when the patella tendon is not shortened but the level of the femorotibial joint line is elevated. The goal of this study was to assess the performance of a technique specifically designed to prevent the occurrence of PPB and its radiological results.

Methods: Ninety-nine patients undergoing total knee arthroplasty were included.

Association between TLR1 polymorphisms and alopecia areata.

Toll-like receptors (TLRs) may contribute to the process of autoimmune attacks on hair follicles. To investigate whether the TLR1 gene polymorphisms are associated with the development and clinical features of alopecia areata (AA), a case-control comparison of two single nucleotide polymorphisms (SNPs) (rs4833095, Asn248Ser and rs5743557, -414C > T) of TLR1 were studied in 239 AA patients and 248 controls. Using multiple logistic regression model, odds ratios, 95% confidence intervals and corresponding p values were estimated.

Easy identification of mechanical axis during total knee arthroplasty.

Purpose: We devised an intraoperatively identifiable mechanical axis (IIMA) as a reference of alignment in total knee arthroplasty (TKA).

Materials And Methods: Between February 2010 and January 2011, primary TKAs were consecutively performed on 672 patients (1007 knees) using an IIMA as a reference in the coronal plane.

Results: The alignment of the lower extremity improved from a mean of 11.

Soft Tissue Balancing of Varus Arthritic Knee in Minimally Invasive Surgery Total Knee Arthroplasty: Comparison between Posterior Oblique Ligament Release and Superficial MCL Release.

Purpose: To assess proper soft tissue balancing of the varus arthritic knee between posterior oblique ligament (POL) release group and superficial medial collateral ligament (SMCL) release group.

Materials And Methods: This retrospective study was performed on 186 patients who underwent minimally invasive surgery (MIS) total knee arthroplasty (TKA) from January 2011 to December 2011. Eighty-three patients were in the group of SMCL release and 103 patients were in the POL release group.
