Case ReportsReverse gracilis muscle flap: an alternative means of skin coverage for recurrent infection after TKA.
Poor wound-healing and skin necrosis are serious but not unusual complications after total knee arthroplasty, and when skin or soft tissue necrosis occurs, reconstructions in the knee area need thin, pliable, tough skin flaps. ⋯ This case suggests that the indications for a reverse gracilis muscle flap could be broadened when other flaps are not available for knee prosthesis coverage.

TKA outcomes after prior bone and soft tissue knee surgery.
Bone surgery around the knee joint could represent a more traumatic prior surgical procedure compared to soft tissue knee surgery and may predispose to differing postoperative total knee arthroplasty (TKA) outcomes. The objective of this study was to analyse the postoperative results as well as complications and failures in two groups of patients that had undergone knee surgery prior to primary TKA (bone surgery and soft tissue surgery) when compared to the no prior surgery group. ⋯ This study confirms that prior knee surgery could be considered a clinical condition predisposed to higher postoperative complication rate in primary TKA compared to the no prior surgery group. After analysing the three study groups, group C showed a higher rate of postoperative local complications and lower IKS knee scores, while the group B showed the poorest postoperative mean values of knee flexion as well as the need for extended surgical approach (TTO approach) was more prevalent in this study group. However, statistical analysis did not reveal a direct correlation between the type of prior knee surgery and TKA failures.

Decreased ratios of lateral to medial patellofemoral forces and pressures after lateral retinacular release and gender knees in total knee arthroplasty.
To demonstrate that lateral to medial patellofemoral force and pressure ratios could be a surrogate marker of retinacular tension and patellar tracking. ⋯ Use of lateral to medial patellofemoral force ratios as a surrogate objective marker for patellar tracking was validated in this study by decreasing ratios observed after lateral release in TKA and with gender-specific implants.
