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: 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: 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: The study aims to determine the relationship between the severity of tear gap resulting from MMPR tear and medial meniscal extrusion, cartilage, bone, and ligament lesions on MRI. The study found that patients with wider tear gap had higher medial meniscal extrusion and higher grade of medial femoral condylar chondromalacia. Therefore, determining the tear gap size in MRI evaluation of root ligament tears is important in predicting internal derangement of the knee joint.

Summary: The effect of coronal plane alignment on the outcomes of repairs of the medial meniscus root is still uncertain. Increased preoperative varus alignment is associated with higher failure rates and lower patient-reported outcomes after isolated repair of the medial meniscus root.

Summary: Material and microstructural properties of meniscus roots were measured using mechanical testing and quantitative polarized light imaging. The study found that anterior roots have larger moduli and higher average DoLP values compared to posterior roots. Posterior roots have higher standard deviation angle of polarization. Lateral roots have greater moduli values compared to medial roots.

Summary: This study aimed to compare the impact of root tears (RTs) and nonroot tears (NRTs) on knee osteoarthritis (OA) and identify factors associated with radiographic worsening of OA in knees with RTs. The study found that RTs were associated with the development and progression of OA, especially in knees without pre-existing OA.

Summary: Medial meniscus posterior root repair significantly reduces rates of radiographic OA progression and conversion to TKA at >60-month follow-up. These findings suggest consideration of repair of MMPRTs for improved outcomes when degenerative changes are not severe.

Summary: This study reviewed the complications and adverse events after isolated medial meniscus posterior root (MMPR) repair. The overall incidence of complications was 9.7%, with the most common being progressive degenerative changes within the knee. Repair failures occurred in 3% of patients.

Summary: This study evaluates the effect of age on joint survivorship after arthroscopic partial meniscectomy for degenerative medial meniscus tears. The results suggest that age itself does not significantly affect joint survival, but other factors related to cartilage status and meniscal tear pattern have a greater impact. For older patients, arthroscopic treatment can still be a viable option if performed with caution.

Summary: The study compared the surgical outcomes of arthroscopic transtibial pullout repair of MMRT based on the degree of lower extremity varus alignment. There were no significant differences in surgical outcomes between the groups in subjective and objective aspects, and both groups showed overall degenerative changes in the knee without differing progression rates.

Summary: This study aimed to identify risk factors for osteoarthritis progression after conservative treatments for isolated medial meniscus posterior root tear (MMPRT). The results showed that age and meniscal extrusion were determining factors of osteoarthritis progression, and the risk decreased when the patient's age was over 63.5 years.

Summary: The study described a non-anatomic arthroscopic all-inside repair technique for medial meniscus posterior root tears in middle-aged and older patients, showing good clinical outcomes and structural healing. The method was effective in treating MMPRTs in this patient population as an alternative to the transtibial pullout repair technique.

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: A new classification system for foot MPPP in young children based on IOA findings was proposed in this study, dividing MPPP into 2 major types (type A and type B) and further into 4 subtypes based on the shape of the PIP joint. This classification system helped determine excisional level and side during surgery, with excellent interobserver reliability.

Summary: This study investigated the clinico-radiological factors associated with future surgical treatment in patients with pediatric flexible flatfoot (FFF) who first visited the orthopedic clinic before the age of 10 years. The study found that unilateral involvement, older age, smaller calcaneal pitch angle, and higher talo-first metatarsal malalignment were high-risk factors for pediatric FFF surgery.

Summary: This study is the first to statistically prove that the difference between TT-TG in MRI and CT originates from the different degrees of knee flexion. Imaging is recommended to be performed with the knee flexed at least 10 degrees for more reliable measurements.

Summary: This study investigated ten previously healthy male patients who had undergone surgical treatment for Ogden type IV tibial tuberosity fractures. The fractures resulted from jump-landings and the leading cause for surgery was unacceptable angular deformity. Entrapped periosteum on the anteromedial side of the proximal tibial physis was the primary obstacle in achieving adequate reduction, which was successfully achieved through surgery. All patients reached skeletal maturity within 2 postoperative years with no significant deformities or functional deficits.

Summary: The study found that pediatric orthopaedic surgery (POS) diseases have high admission rates in tertiary hospitals, while adult orthopaedic surgery (AOS) diseases have low rates. Due to the current classification criteria leading to underestimation of POS diseases in terms of severity, tertiary hospitals may intentionally reduce admissions of children with POS diseases, potentially impacting their access to professional care.
