The discoid lateral meniscus (DLM) is an anatomically abnormal meniscus that covers a greater area of the tibial plateau than the normal meniscus. The DLM is classified into two types: complete (CDLM) and incomplete (ICDLM) types. In this study, we investigated the histological and cell biological characteristics of CDLM and ICDLM. The number of blood vessels, proteoglycan deposition, and collagen distribution were assessed using meniscal tissues. Collagen production was also investigated in CDLM and ICDLM cells. The intercondylar region of the CDLM had a higher number of blood vessels than the inner region of the ICDLM. Safranin O staining density and type II collagen deposition in ICDLM were higher than those in CDLM. Type II collagen-positive cells were higher in ICLDM than in CDLM. CDLM cells showed slender fibroblastic morphology, while ICDLM cells were triangular chondrocytic in shape. This study demonstrated that the intercondylar region of the CDLM showed similar properties to the outer region of the meniscus. The inner region of the ICDLM, on the other hand, differed from the intercondylar region of the CDLM. Our results suggest that the intercondylar region of the CDLM may have a high healing potential like the outer meniscus.

Department of Orthopaedic Surgery, LSU Health Shreveport, Shreveport, LA, USA.
Introduction: Distal femoral cartilage lesions can be treated using osteochondral autograft transfer (OAT). When impacting plugs into a recipient site, the cartilage may fracture. This study aimed to analyze OAT donor regions and impaction energies to identify characteristics that lead to fracture.

Article Synopsis
- Intraarticular knee fractures are significant and need proper treatment for better recovery outcomes, with cleavage fractures being a rare type that involves limited areas of the distal femur without additional complications.
- The article presents two case studies: one of a young adult treated successfully without surgery and another adolescent who required minimal-invasive surgical intervention.
- Both patients achieved excellent healing and returned to full function, with follow-up periods of nine and eleven months showing positive results.
[Refixation of a posterior medial root lesion in combination with centralization by a meniscotibial suture].
Oper Orthop Traumatol
August 2024
Klinik für Orthopädie und Unfallchirurgie, Martin-Luther-Krankenhaus Berlin, Caspar Theyß-Str. 27-31, 14193, Berlin, Deutschland.
Objective: Refixation of a posterior root lesion of the medial meniscus via a tibial drill tunnel and prevention of extrusion using a meniscotibial suture (centralization).
Indications: Posterior root lesion of the medial meniscus.
Contraindications: Grade 4 cartilage damage in the corresponding compartment, uncorrected varus or valgus deformities, symptomatic instabilities, extensive degenerative tears apart from the root region.
Outcomes of Osteochondral Autologous Transplantation with Ipsilateral Lateral Talar Autograft for Medial Osteochondral Lesions of the Talus.

Department of Orthopedic Surgery, Dankook University College of Medicine, Cheonan, Korea.
Background: Osteochondral autologous transplantation (OAT) has been widely used in the treatment of osteochondral lesion of the talus (OLT). Previous studies have reported successful outcomes following the use of osteochondral autogenous grafts from the intercondylar notch of the knee or a non-weight-bearing region of the femoral condyle. However, donor-site morbidity of the knee joint has been observed in several cases.

Background: Distal femur fractures remain treatment challenges with a considerable postoperative non-union rate. Concern remains that surgery may compromise osseous vascularity. This study aimed to determine effects of retrograde femoral intramedullary nailing (RFIN) on distal femur vascularity, and the locations of the middle genicular artery terminal branches in relation to the standard RFIN entry point.
