Proper femoral component placement plays a key role in the success of a total knee replacement (TKR). Controversy exists on which technique should be used to ensure proper femoral component placement. This two-part study compares gap balancing (GB) and measured resection (MR) techniques used in TKR, investigating femoral component position and early clinical outcomes. Femoral component position was analyzed in 95 consecutive knees that underwent primary TKR. Both GB and MR cutting blocks from the same knee system were sequentially placed on the operative knee, marking the pin sits. A standardized photograph (Figure) was taken prior to making final femoral cuts. Relative rotation was determined based on measurements made from a commercially available software. Clinical comparison was made using 50 consecutive GB patients and 50 consecutive MR patients. Clinical outcome measures were Knee Society Scores (KSS), knee range of motion (ROM), functional ROM (FROM), tourniquet time, and patients having manipulations under anesthesia (MUA).Background

Periprosthetic joint infection (PJI) is a devastating complication and interest exists in finding lower cost alternatives to current management strategies. Current strategies include a two-stage revision with placement of an antibiotic spacer and delayed placement of a new arthroplasty implant. This study aimed to show that biofilm residue can be reliably eradicated on infected implants, safely allowing re-implantation in a spacer. Strains of Background
