Surprise Baby: Abdominoplasty Performed During Unknown Pregnancy.

Abdominoplasty is a commonly performed procedure for patients after significant weight loss and in postpregnancy women. Stable weight and completed family planning are critical for optimal outcomes, as pregnancy postabdominoplasty can increase risks for both mother and fetus and potentially compromise aesthetic results. We present the first reported case of a patient undergoing abdominoplasty while unknowingly pregnant.

Total knee arthroplasty without patella resurfacing leads to worse results in patients with patellafemoral osteoarthritis Iwano Stages 3-4: a study based on arthroplasty registry data.

Purpose: To determine whether the preoperative degree of degeneration of the patellofemoral joint really affects the outcome of total knee arthroplasty (TKA) surgery without patella resurfacing and thus to establish a parameter that might serve as a guiding factor to decide whether or not to perform retropatellar resurfacing. It was hypothesized that patients with preoperative mild patellofemoral osteoarthritis (Iwano Stages 0-2) would significantly differ from patients with preoperative severe patellofemoral osteoarthritis (Iwano Stages 3-4) in terms of patient-reported outcome (Hypothesis 1) and revision rates/survival (Hypothesis 2) after TKA without patella resurfacing.

Methods: Application of a retrospective-comparative design on the basis of Arthroplasty Registry data that included patients with primary TKA without patella resurfacing.
