Patellofemoral arthritis that is due to patellofemoral instability or chronic patellofemoral maltracking can be a difficult treatment problem. Isolated patellofemoral arthroplasty (PFA) is a good option that preserves bone and can more accurately reproduce native kinematics when compared with total knee arthroplasty. Newer PFA designs have demonstrated improved survivorship, although survivorship has not shown equivalence with total knee replacement.

A retrospective chart review at two level 1 trauma centers was completed. Clinical parameters including demographics and comorbidities were evaluated in addition to hospital and clinical data.

Design: Consecutive retrospective case review.
Setting: St.
Objectives: Using a cadaveric 3-part fracture model and cyclic loading protocol, our study objectives were to quantify the stabilizing effect of tension-reducing rotator cuff sutures in terms of fracture displacement across the surgical neck and greater tuberosity compared with a control group in which no sutures were used.
Methods: Six matched pairs of fresh frozen specimens underwent a standardized, 3-part, proximal humerus fracture and were split into 2 groups. The control group had the fracture fixed with a plate and screw construct only while the experimental group had additional suture fixation through the plate to each rotator cuff tendon.
