Endoscopic surgery can replace operative procedures. The evolution of arthroscopy leads to realize intra articular surgery more and more complicated. However, any surgical procedure involve some risks, and surgeons have to be prudent in use of new instruments or new technics. These need a radio surgical environment adapted to all surgery.

Clinical and Radiological Outcomes After Lateral Meniscal Allograft Transplantation Through a Medial Arthrotomy: A Minimum 4-Year Follow-up.
Orthop J Sports Med
January 2025
Department of Orthopaedic Surgery, Case Western Reserve University, Cleveland, Ohio, USA.
Background: Previous studies have demonstrated that lateral meniscal allograft transplantation (MAT) through medial arthrotomy showed less extrusion than that of the lateral arthrotomy. However, there is a paucity of literature reporting clinical and radiological outcomes after lateral MAT through the medial arthrotomy.
Hypothesis: Lateral MAT through a medial arthrotomy would show significantly improved clinical scores and minimal joint space narrowing compared with preoperative status.
Radial Tear of the Midbody in Complete Discoid Lateral Meniscus: A Case Report.

To the best of our knowledge, there are no reports on the results of the repair of radial tears of the midbody of the complete discoid lateral meniscus (DLM). A 14-year-old female underwent meniscal replacement with autologous tendon transplantation for early re-tear after repair of the radial tear in the midbody of complete DLM. Two years after the tendon transplantation, there was no effusion or swelling, and the patient was able to exercise completely without symptoms.

Introduction: Despite the good clinical outcomes of osteochondral autograft transplantation (OAT), reports of re-arthroscopic findings after OAT have been limited to short-term, and there are no reports of findings after long-term follow-up. This is the first report that describes re-arthroscopic findings long-term after OAT.
Case Report: A male patient underwent OAT on the lateral femoral condyle (LFC) of the knee and lateral meniscus (LM) repair at the age of 45.
Biomechanical Properties of Meniscal Repair Versus Meniscectomy for Horizontal Meniscal Tears: A Systematic Review.
Am J Sports Med
January 2025
Department of Orthopedic Surgery, Columbia University Irving Medical Center, New York, New York, USA.
Article Synopsis
- Limited biomechanical research explores how horizontal meniscus tears (HMTs), meniscal repair (MR), and meniscectomy affect knee biomechanics, prompting this systematic review to investigate changes in knee contact mechanics following these conditions.
- A total of 6 studies were analyzed, revealing that HMTs increase peak contact pressure (PCP) by 14.2% and decrease contact area (CA) by 7.1%; partial meniscectomies (PM) also raised PCP significantly while reducing CA, and complete meniscectomies (CM) resulted in even higher increases in PCP (54.5%).
- Meniscal repair (MR) showed no significant difference in PCP or CA compared to intact menisci, indicating that it
Varus alignment of the hip and knee 2 years after anterior cruciate ligament injury is associated with medial tibiofemoral osteoarthritis 3 years later.

Purpose: To investigate if hip and knee alignment assessed 2 years after anterior cruciate ligament (ACL) injury is associated with compartment-specific radiographic knee osteoarthritis (OA) 3 years later.
Methods: An exploratory analysis was conducted in the knee ACL, nonsurgical versus surgical treatment (KANON) trial (ISRCTN84752559); 115 subjects with acute ACL injury were assessed at the 2-year follow-up; full-limb images of the injured leg were acquired, and the neck-shaft angle (NSA) and hip-knee-ankle angle (HKA) were measured. At the 5-year follow-up, weight-bearing tibiofemoral and patellofemoral radiographs were obtained.
