Case: A 13-year-old adolescent boy and a 12-year-old girl, with torn anterior cruciate ligament (ACL) and increased posterior tibial slopes (PTS) of 17° and 19°, underwent transphyseal anterior tibial hemiepiphysiodesis and ACL reconstruction using a quadriceps autograft. Epiphysiodesis plates were removed after epiphyseal closure in the girl and after 12 months in the boy. Follow-up at 12 and 15 months showed Tegner and Lysholm scores of 4 and 100, with PTS reduced to 8° and 9°.

Recent findings suggest a slight but significant reduction of the medial proximal tibial angle (MPTA) resulting in a varus knee where the sagittal osteotomy plane is based on a total of two guide wires defining the osteotomy wedge without respecting the frontal plane. We hypothesize that the placement of a total of four guide wires intraoperatively can reduce the influence on the MPTA.

Previous research indicates that in posterior cruciate ligament (PCL) reconstruction the laxity is affected by the tibial slope (TS). However, there is currently no literature evaluating the impact of TS on surgical outcome in combined reconstruction of PLC/PCL.

- This study evaluated the effectiveness of two ACL restoration techniques—repair with internal bracing (ACLIB) and reconstruction with autograft (ACLR)—in treating acute knee dislocations, highlighting ACLR as offering better stability, especially at 12 months post-surgery.
- A total of 20 patients were included, and outcomes were assessed through patient-reported measurements and stress tests, showing ACLR had significantly lower tibial translation compared to ACLIB at the 24-month follow-up.
- Both techniques produced good patient satisfaction scores, but knee stiffness was a common complication, which was effectively treated with early arthroscopic procedures.
Purpose: To characterize and compare the quality of regenerative cartilage tissue (ReCT) after conventional minced cartilage (CMC) and arthroscopic minced cartilage (AMC), in terms of cell viability, gene expression, and matrix synthesis and to investigate the influence of different shaver types.
Methods: Chondral tissue was harvested from the knees of 8 porcine donors. Porcine specimens were euthanized one day before harvest.
