Minimally invasive total knee arthroplasty is a relatively new technique. There are limited clinical data on outcomes in patients having this procedure. We report the incidence of lateral release of the patella during total knee arthroplasty performed by one surgeon in 106 consecutive knees.

Unlabelled: Minimal-incision total knee arthroplasty can be considered part of the continuum from traditional extensile exposures to the quadriceps-sparing approach. We did this study to identify preoperative variables that predict which patients are amenable to a mini-incision and mini-arthrotomy technique, and to compare early outcomes in these patients versus patients in whom a standard approach was required. A consecutive series of 118 primary total knee arthroplasties were evaluated.

Mini-incision total knee arthroplasty can be accomplished through versions of exposures used in standard total knee arthroplasty. Modifications of the medial parapatellar, subvastus, and midvastus approaches are presented, and potential advantages and disadvantages of each approach are reviewed. When making the transition to smaller incisions and arthrotomies, the medial parapatellar seems to be the most versatile.

Interest is growing in blood conservation and avoidance of transfusion in patients undergoing orthopedic surgery, especially in the field of joint replacement. Several methods have proven successful in reducing intraoperative blood loss, which can translate into lessened allogeneic and autologous transfusion requirements. Available techniques include acute normovolemic hemodilution, hypotensive anesthesia, intraoperative blood salvage, specialized cautery, topical hemostatic agents, and pharmacologic agents given in the perioperative period.

Seventeen amputations (in 14 children) with established overgrowth were treated by capping of the residual limb with a polytetrafluoroethylene (PTFE) felt pad. Average age at the time of the procedure was 7 years 10 months. Mean follow-up was 4 years 9 months.

Background: Fracture-healing slows with age. While six-week-old rats regain normal bone biomechanics at four weeks after a fracture, one-year-old rats require more than twenty-six weeks. The objective of this study was to examine the possible role of altered mRNA gene expression in this delayed union.

The best method for processing allograft bone to prevent disease transmission without compromising its biomechanical function is not yet determined. We evaluated the biomechanical effects of processing bulk allograft bone segments with negative-pressure washing. Specimens were prepared from matched pairs of adult cadaveric femurs.
