Randomized Controlled Trial Comparative Study Clinical Trial
The use of cold compression dressings after total knee replacement: a randomized controlled trial.
This prospective, controlled study compared cold compressive dressings with wool and crepe in the postoperative management of patients undergoing total knee replacement (TKR). Forty TKR patients were assessed for blood loss, pain, swelling, and range of motion. ⋯ Mean opiate requirements were lower in the cold compression group (0.57 versus 0.71 mg/kg/48 hours). The cold compression device appeared to reduce blood loss and pain following TKR.

Randomized Controlled Trial Clinical Trial
The medial trivector approach in total knee arthroplasty.
This study compares the clinical results of the medial trivector approach to the standard parapatellar approach in primary total knee arthroplasty. Ten patients undergoing simultaneous bilateral total knee arthroplasty were included in this study. Right and left knees were randomized for a standard medial parapatellar arthrotomy or a medial trivector approach. ⋯ Subjectively, patients reported less discomfort and more strength in the knees having undergone a medial trivector approach. The medial trivector approach may enhance postoperative recovery without adversely affecting the quadriceps function following total knee arthroplasty. The medial trivector approach to the knee does not weaken quadriceps muscle function or adversely affect clinical results of total knee arthroplasty.
