ReviewBi-cruciate retaining total knee arthroplasty: a systematic literature review of clinical outcomes.
Total knee arthroplasty (TKA) has been shown to have good long-term outcomes and survivorship. Nonetheless, dissatisfied patients are frequently reported in the literature. Bi-cruciate retaining total knee prostheses (BCR TKA) were designed to address the demand for more kinematically functional implants that better reconstruct natural knee kinematics. ⋯ The literature has not shown clear indications and guidelines for the use of BCR implants. The promising results of first generation BCR TKA designs may be optimized through improved implant designs in the future. Further studies are advocated to provide the necessary evidence of second generation BCR TKA designs.

Excellent outcomes after double-locked plating in very low periprosthetic distal femoral fractures.
Very low periprosthetic distal femur fractures (PPDFFs) are rare injuries and often have a relatively high failure rate after single lateral locked plating. The double plating technique yields good outcomes in osteoporotic fractures of the distal femur. To date, there is limited information on double-locked plate fixation of very low PPDFFs. This study aimed to evaluate the outcomes and complications of surgically treated very low PPDFFs using double-locked plate fixation. ⋯ Double locked plating showed excellent radiographic and functional outcomes with few complications in patients with very low PPDFFs. Based on these promising results, we propose the consideration of double-locked plate fixation in the treatment of very low PPDFFs.

Meta AnalysisIncidence of nonunion after surgery of distal femoral fractures using contemporary fixation device: a meta-analysis.
Nonunion is the most frequent cause of reoperation and is associated with high morbidity after distal femur fracture (DFF). We examined the rates of nonunion requiring reoperation after fixation for DFF using a locking compression plate (LCP) or retrograde intramedullary nail (RIMN). ⋯ Approximately 5% of patients who underwent LCP or RIMN fixation developed nonunion. Therefore, LCP and RIMN are effective DFF techniques and mastering one of them is essential.

ReviewLateral retinacular release combined with MPFL reconstruction for patellofemoral instability: a systematic review.
The role of the lateral retinaculum in patellofemoral instability is still debated. Lateral retinacular release (LRR), has been extensively performed in combination with different surgical procedures, including reconstruction of medio-patellofemoral ligament (MPFL). Despite controversial indications, the results from these studies seem promising. The present study conducts a systematic review about current biomechanical and clinical evidence concerning the role of LRR in combination with MPFL reconstruction. We performed a comprehensive literature research, comparing the outcomes of MPFL reconstruction with and without LRR. ⋯ IV, Systematic review.
