Summary: The study compared the biomechanical properties of two techniques (TPO and ASA) for repairing posterior medial meniscal root tears (PMMRT). Results showed that the ASA technique demonstrated superior biomechanical properties in terms of contact surface area and restored tibiofemoral contact mechanics to be comparable with the intact knee, while the TPO technique showed significant differences compared with the intact knee.

Summary: Anterior cruciate ligament (ACL) injury and meniscal tear (MT) contribute to the development of post-traumatic osteoarthritis (PTOA), possibly through the activation of complement proteins and infiltration of immune cells in the synovium. This study found that discarded surgical synovial tissue (DSST) from patients undergoing ACL and MT repair had increased presence of complement proteins and immune cells compared to uninjured controls. Specifically, ACL injury led to a greater activation of complement and increased infiltration of mast cells and macrophages compared to MT injury. These findings suggest that complement activation and immune cell infiltration may play a role in the development of PTOA after ACL and MT injuries.

Summary: The study aimed to evaluate the clinical and radiological outcome of posterior lateral meniscus root (PLMR) repair accompanying anterior cruciate ligament (ACL) reconstruction. The results showed high healing rates of PLMR repair and no significant increase in coronal meniscal extrusion following the repair. The healing status of PLMR showed no significant association with meniscal extrusion or patient-reported outcome measures (PROMs), but a greater increase in coronal meniscal extrusion negatively affected the clinical results.

Summary: Surgical repair of meniscus injury aims to alleviate pain, prevent exacerbation of the injury, restore normal knee function, and inhibit accelerated development of post-traumatic osteoarthritis. Current surgical approaches do not eliminate the risk of accelerated PTOA. Innovative strategies utilizing biologics, allografts, and scaffolds are being explored for potential treatments, but the impact on PTOA development is often overlooked.

Summary: Tissue adhesives (TAs), particularly fibrin-based TAs, show promising results for meniscal repair, either as an augmentation or primary repair method for various configurations of meniscal tears. However, there is a lack of high-quality comparative evidence supporting routine use of TAs for meniscal repair and an absence of an ideal TA designed for this purpose, emphasizing the need for further high-quality research to develop new materials and test their suitability for use in meniscal repair.

Summary: This study investigated the histopathologic effects of different treatment options on medial meniscus posterior root tear. The results showed that meniscus root repair can't completely stop the progression of knee osteoarthritis, but it leads to significantly less severe degenerative changes compared to partial meniscectomy and nonoperative treatment.

Summary: Meniscus root tears can lead to altered joint biomechanics and accelerated articular cartilage degeneration, with arthroscopic repair potentially resulting in slower radiological deterioration compared to meniscectomy and nonoperative management. However, age is not a significant predictor of functional outcome in treatment of acute MRTs. Further high-quality studies are needed to better understand optimal management strategies.

Summary: This study discusses the impact of posterior medial meniscus root tears (PMMRTs) on the progression of osteoarthritis (OA) and the consequences of nonanatomic root repairs, finding that the injuries lead to an increase in contact pressure in the medial compartment and a decrease in contact area. Through a case series, it is discovered that nonanatomic repairs can result in meniscal extrusion and symptomatic meniscal extrusion.

Summary: The purpose of this study was to evaluate the potential benefit of meniscus tear repair within 3 weeks after rupture compared with more than 3 weeks after rupture. The results showed that patients who underwent repair within 3 weeks had a significantly lower failure rate (3.3%) compared to those who underwent repair at 3 weeks or more (20.0%). Therefore, early repair of meniscus tears is beneficial and can prevent failure of meniscus repair surgery.

Summary: Patients with medial meniscus ramp lesions undergoing ACLR are more likely to have a higher posterior tibial slope and meniscal slope, as well as bone bruises in both the medial and lateral tibiofemoral compartments. However, bone bruises involving only the lateral compartment are more common in patients without ramp lesions. No significant differences were found in tibial and meniscal slopes between patients with or without ramp lesions undergoing ACLR.

Summary: The study revealed that in ACL-injured patients, a preoperative grade III PS was mainly associated with a higher amount of intra-articular soft-tissue damage and chronicity of the injury. Patients with complete chronic ACL injuries and bimeniscal tears were more likely to have a preoperative grade III PS than their acute counterparts. This suggests that grade III PS may be an early sign of knee decompensation of dynamic rotational knee laxity in chronic ACL-injured knees with bimeniscal lesions.

Summary: An online survey was conducted among elite athletes to assess the impact of COVID-19 vaccination on physical performance. Results showed that 72% of athletes perceived no change, 4% perceived improvement, and 24% perceived a negative impact on physical performance following full vaccination. Factors such as individual sport, longer duration of vaccine reactions, higher level of vaccine reaction, and perceived pressure to get vaccinated were associated with a negative impact on physical performance lasting more than 3 days.

Summary: The surgical management of medial meniscus ramp lesions is challenging. Current repair techniques lack direct visualization of the injured structures, making precise evaluation and anatomical repair difficult. A recently described 2-portal posteromedial approach provides better visualization of the tear and identification of the injured structures.

Summary: The purpose of this review is to provide an overview of recent scientific literature on ramp lesions of the medial meniscus and to summarize the current evidence on their prevalence, classification, biomechanics, surgical techniques, and clinical outcomes. Ramp lesions may be present in about 1 in 5 patients undergoing ACL reconstruction and in almost half of the medial meniscal tears observed in this population. There is no consensus on whether and when ramp lesions should be surgically treated. The subtype, size, and stability of the lesions may influence the decision-making process.

Summary: PCL reconstruction is a technically demanding surgery, and optimal identification of the femoral and tibial anatomical footprints is crucial. Creating a posteromedial portal is recommended to aid in tibial tunnel placement. Adding a second portal could further improve the reconstruction process by enhancing anatomical footprint identification, clearing the stump, and facilitating graft passage.

Summary: Ramp lesions of the medial meniscus and posterior lateral meniscus root tears can occur simultaneously in up to 8% of patients undergoing ACL reconstruction. The prevalence of these complex meniscal tears increases with the severity of the injury. Surgeons have recently shown interest in the posteromedial structures of the ACL-injured knee, which were previously overlooked. However, there is a lack of literature regarding proximal posteromedial capsular lesions, whether isolated or associated with complex meniscal injuries.

Summary: Proximal tibial osteotomy is an effective procedure for symptomatic unicompartmental osteoarthritis and malalignment in active and young adult patients. However, it is associated with various complications such as fractures, delayed or non-healing, neurovascular issues, correction loss, implant-related problems, patellofemoral complaints, biological complications, and limb length changes. Understanding these problems can help reduce their occurrence and improve surgical outcomes.
