Ligamentum teres injury is associated with the articular damage pattern in patients with femoroacetabular impingement.

Purpose: The objective of this study was to investigate the association between ligamentum teres injury and the hip joint cartilage damage pattern in patients with femoroacetabular impingement.

Methods: We compared articular cartilage damage between ligamentum teres-intact and-ruptured hips. Data were collected for 77 consecutive patients with femoroacetabular impingement who underwent hip arthroscopy.

Outcomes of knee arthrodesis following infected total knee arthroplasty: a retrospective analysis of 8 cases.

Background: There is insufficient information regarding patient-based outcomes after knee arthrodesis following infected total knee arthroplasty (TKA). The purpose of this study was to analyze outcomes in patients who underwent knee arthrodesis following infected TKA using clinical and radiographic measurements including a patient-based outcome measuring system.

Methods: We evaluated 8 patients (mean age 72.

Topographical histology of the posterolateral corner of the knee, with special reference to laminar configurations around the popliteus tendon: a study of elderly Japanese and late-stage fetuses.

We investigated the histology of laminar configurations at the posterolateral corners of 40 knees (18 late-stage fetuses, 22 elderly persons). In the fetuses, the deeply located popliteal fascia and the superficially located inferior geniculate vascular sheath were evident in a space between the popliteus tendon (PT) and the biceps femoris and gastrocnemius. Along, and deep to, the popliteal fascia, the popliteus muscle parenchyma developed into both the PT and another dense connective tissue mass.

Does the fabella contribute to the reinforcement of the posterolateral corner of the knee by inducing the development of associated ligaments?

The fabellofibular (FF) and arcuate ligaments are closely colocated at the posterolateral corner of the knee. However, a bony fabella is often absent in Japanese subjects. We investigated these structures morphometrically using 212 knees.

Lateral ligament injury of the ankle and associated articular cartilage degeneration in the talocrural joint: anatomic study using elderly cadavers.

We investigated degenerative changes (DCs) of the articular cartilage using 33 cadaveric talocrural joints with anterior talofibular ligament injuries. The control group (93 normal ankles) were age- and sex-matched with the injury group. The injured ligament carried unusual wavy collagen bundles with hyalinization (or elongation) or rupture with scar.
