Purpose: To biomechanically evaluate a flat posterior cruciate ligament (PCL) reconstruction utilizing rectangular femoral bone tunnels.
Methods: Eight fresh-frozen human knee specimens were tested in a six-degrees-of-freedom robotic test setup. In each testing step, a force-controlled test protocol was performed, including 89 N posterior tibial translation (PTT) in neutral, internal and external rotation, from 0 to 90° of flexion.
Article Synopsis
- - The case report discusses a new treatment for chronic knee pain, particularly when other therapies have failed, highlighting a patient who underwent MRI-assisted chemical neurolysis targeting the genicular nerve.
- - A 62-year-old man experienced significant pain relief for four months after the procedure, suggesting that this method could be an effective option for those with persistent knee pain.
- - Despite promising results, further research, including controlled trials, is needed to fully assess the safety and effectiveness of this treatment before it can be commonly used in clinical practice.
Article Synopsis
- Injuries to the knee's ligaments, especially the superficial medial collateral ligament (sMCL), can make the knee move too much in certain ways, which isn't good.
- The study aimed to see if a special surgery could help fix these knee movement problems by reconstructing the injured ligaments.
- After testing on knee samples, they found that the surgery successfully restored the knee’s movements to normal levels, just like a healthy knee.
Purpose: To compare patient-reported outcomes measurements and subsequent surgical interventions in patients treated with anterior cruciate ligament reconstruction (ACLR) using either quadriceps tendon autograft with a patellar bone block (bQT) or soft tissue only (sQT).
Methods: All ACLRs performed between January 2010 and March 2022 were prospectively followed for 24 months and retrospectively evaluated. All primary ACLRs with full 24 months of follow-up data, without any previous surgery or any additional ligamentous interventions, were matched for major ACL risk factors, including sex, age, Tegner activity level [TAL], pivoting sports, and concomitant injuries.
Isometry of anteromedial reconstructions mimicking the deep medial collateral ligament depends on the femoral insertion.

Article Synopsis
- This study investigates how the deep medial collateral ligament (dMCL) and potential anteromedial (AM) reconstructions change in length during knee flexion to improve understanding of anteromedial rotatory instability (AMRI).
- Using cadaveric knee specimens, researchers measured length changes in the dMCL and simulated AM reconstructions by marking insertion points and testing with a kinematic rig at varying degrees of knee flexion.
- Results showed that the length changes of the dMCL parts differed during flexion, and the effectiveness of AM reconstructions was primarily affected by the femoral attachment position, suggesting that surgeons should prioritize positioning in the posterior aspect for better control of AMRI.
