Is Previously Implanted Osteosynthesis Material an Obstacle for the Use of Customized Guides?: A Case Report.

Case: We present the case of a 46-year-old patient with asymmetric deformity in the posterior tibial slope after previous high tibial osteotomy surgeries with the presence of a medial osteotomy plate. A customized cutting guide was designed to fit on the plate to perform a single surgery and avoid possible soft-tissue complications after multiple surgeries.

Conclusions: The presence of a previous internal fixation device may affect the manufacture of 3-dimensional cutting guides.

Obesity and Meniscal Transplant Failure: A Retrospective Cohort Study.

The purpose of this study was to analyze the effect of obesity and other clinical factors on the outcome of meniscal allograft transplantation (MAT) with transosseous fixation. A retrospective cohort study was performed on patients who underwent a MAT between 2002 and 2017. All the participants had a minimum follow-up period of 24 months.

Extensor Mechanism Allograft in Osteosarcoma of the Patella: A Case Report.

Case: A 24-year-old female diagnosed with fibroblastic osteosarcoma of the patella underwent a total patellectomy and surgical reconstruction with a large bone-tendon allograft of the extensor mechanism and adjuvant chemotherapy. At 5 years' postoperative, the patient has adequate disease control and excellent joint function.

Conclusions: Reconstruction with an extensor mechanism allograft is an appropriate alternative for patients with malignant patella tumors without tumor contamination of the joint, allowing for satisfactory knee function and disease control.
