We present a case of a chondral lesion after anterior cruciate ligament (ACL) reconstruction caused by femoral cross-pin breakage and intra-articular migration of the fragment. A 20-year-old man initially underwent ACL reconstruction using a hamstring autograft. The RigidFix bioabsorbable cross-pin (DePuy Mitek) was used for the femoral fixation. The patient returned to a pre-injury level of activity (professional soccer player) 6 months postoperatively. However, 20 months postoperatively, the patient presented with effusion and lateral joint-line pain after practice, without signs of instability in clinical examination. Conservative treatment failed and at re-arthroscopy a chondral lesion of the lateral femoral and tibial condyle was found, which had been caused by the broken femoral cross-pin. The fragment was removed and the symptoms resolved. Orthopaedic surgeons should be aware of this complication when using a bioabsorbable cross-pin for femoral fixation in ACL reconstruction.

Background: Revision anterior cruciate ligament (ACL) reconstruction has been documented to have inferior outcomes compared with primary ACL reconstruction. The reasons why remain unknown.
Purpose: To determine whether surgical factors performed at the time of revision ACL reconstruction can influence a patient's outcome at 6-year follow-up.

Background Anterior cruciate ligament reconstruction (ACLR) is a common operative procedure and many options regarding the type of the selected graft and fixation technique have been described to date. Although many studies have addressed the issue of the optimal femoral fixation device during ACLR with a hamstring tendon (HT) autograft, no clear evidence to indicate one technique over another has been found. Objective The purpose of this study was to compare the long-term postoperative outcomes and complication rates between transfemoral Cross-pin (CP) and Endobutton-Cortical Button (CB) fixation techniques in patients undergoing ACLR with an HT autograft.

Background An anterior cruciate ligament (ACL) tear is one of the most common sports injuries in the knee region. Currently, anatomical ACL reconstruction with quadrupled hamstring tendon autograft and controlled accelerated rehabilitation is a frequently used treatment approach. This study aims to add to the literature the early and mid-term clinical results of the controlled accelerated rehabilitation program we implemented in our clinic to enable patients to return to their daily activities faster after ACL reconstruction.

Article Synopsis
- The study compares the biomechanical stability of two techniques for fixing pediatric supracondylar femur fractures using Kirschner wires (K-wires), focusing on retrograde versus antegrade methods.
- In an experiment with 24 synthetic bone models, the retrograde group exhibited significantly greater strength against varus forces, while both groups showed similar stability in extension strength.
- The findings suggest that while retrograde fixation is better for preventing varus deformities, antegrade fixation may be preferred to lower the risk of septic arthritis post-surgery.
Outcomes of RigidFix Cross Pin Fixation in Femoral and Tibial Tunnel for Anterior Cruciate Ligament Reconstruction.

Article Synopsis
- The study evaluates the effectiveness of RigidFix cross pins fixation for tibial tunnel in anterior cruciate ligament (ACL) reconstruction, comparing two fixation methods over a five-year follow-up period.
- Patients were divided into two groups, with one using RigidFix for both tunnels and the other combining RigidFix with interference screw fixation in the tibial tunnel.
- Results indicated that the group using RigidFix in both tunnels had better postoperative pain scores and functional outcomes at both two and five years compared to the group using mixed fixation methods.
