We describe a special, interesting phenomenon found in the anterior horn of the lateral meniscus (AHLM): most tear patterns in the AHLM are distinctive, with loose fibers in injured region and circumferential fiber bundles were separated. We name it as macerated tear. The goal of this study was to bring forward a new type of meniscal tear in the AHLM and investigate its clinical value.

A Special Tear Pattern of Anterior Horn of the Lateral Meniscus: Macerated Tear.

Long noncoding RNAs serve as novel regulatory molecules involved in various biological processes, but their role in osteoarthritis (OA) remains unknown. Therefore, we aimed to reveal the inflammatory mechanisms regulated by CILinc02 and methylene blue in human osteoarthritic cartilage and to explore the potential functions of CILinc02 and methylene blue in OA. The expression level of CILinc02 in OA cartilage tissues and primary cells was obtained using quantitative reverse transcriptase polymerase chain reaction (qRT-PCR). The cytokines, such as interleukin 1 (IL-1), IL-6, IL-17, tissue inhibitor of metalloproteinase-1 (TIMP-1) and matrix metalloproteinase (MMPs), involved in the degradation of chondrocyte in CILinc02 knockdown OA primary cells, which were treated with methylene blue that were determined by enzyme-linked immunosorbent assay, qRT-PCR and Western blot analysis. The results showed that CILinc02 was overexpressed in osteoarthritic cartilage tissues and in OA primary cells, but methylene blue can inhibit the expression of CILinc02. In addition, overexpression of CILinc02 induced the inflammation and apoptosis in primary OA cells, however, the effect of methylene blue was reversed compared to CILinc02. Meanwhile, methylene blue can regulate the expression of TIMP-1, MMP-1, and MMP-13 proteins, thereby suppressing the degradation of chondrocyte in OA. This evidence indicates that methylene blue can act as an inflammatory inhibitor by targeting CILinc02 to regulate the inflammatory response.

Management of the rotator cuff presents specific challenges to orthopaedic surgeons. Several locking suture methods have been reported but often fail for a number of reasons. We describe a different technique that is easy to perform and inspired by the Chinese knot, an arthroscopic double-locking suture using a footprint ultrasuture anchor. This technique is similar to the suture-bridge structure on the bursal side of the tendon in that it increases tissue grip and stabilizes initial tendon-to-bone fixation. This technique is especially suitable for the patients who have bursal-side partial-thickness or degenerative small- and medium-sized rotator cuff tears.

To bring forward an arthroscopic classification of the popliteomeniscal fascicles of the lateral meniscus (PFLM) tears.

The lateral meniscus is a unique structure of the knee joint, and its anatomy, function, pathological process, and treatment are distinct from those of the medial meniscus. To date, no consensus on the management of lateral meniscal lesions has been published, and clinical decision-making is challenging. To facilitate this, consensus and practice guidelines for lateral meniscal lesions were developed and endorsed by the Chinese Society of Sports Medicine.

Guidelines on the Diagnosis and Treatment of Lateral Meniscal Lesions: A Consensus Statement by the Chinese Society of Sports Medicine.

Discoid lateral meniscus (DLM) is the most common congenital variant of the lateral meniscus, which is prone to degeneration and lesions, and often leads to knee osteoarthritis. At present, there is no consensus on the clinical practice of DLM, and this expert consensus and practice guidelines on DLM was developed and approved by Chinese Society of Sports Medicine according to the Delphi method. Among 32 statements drafted, 14 statements were excluded for redundant information, and 18 statements achieved consensus. This expert consensus focused on the definition, epidemiology, etiology, classification, clinical manifestations, diagnosis, treatment, prognosis, and rehabilitation of DLM. Restoring the normal shape, retaining appropriate width and thickness, and ensuring the stability of the remnant meniscus is critical to sustaining the physiological function of the meniscus and preserving the knee. The partial meniscectomy with or without repair should be the first-line treatment when possible, given that the clinical and radiological long-term outcomes of total or subtotal meniscectomy are worse.

The aim of the study was to investigate the effect of platelet-rich plasma (PRP) on subchondral bone marrow edema (BME) and the level of biomarkers in synovial fluid of the knee osteoarthritis.

To explore the effectiveness and advantages of using Fastpass Scorpion suture passer to stitch the inferior capsulolabral complex in arthroscopic Bankart repair compared with traditional arthroscopic suture shuttle.

In the recent decade, there has been substantial progress in the technologies and philosophies associated with diagnosing and treating anterior cruciate ligament (ACL) injuries in China. The therapeutic efficacy of ACL reconstruction in re-establishing the stability of the knee joint has garnered widespread acknowledgment. However, the path toward standardizing diagnostic and treatment protocols remains to be further developed and refined.

Diagnosis and treatment of anterior cruciate ligament injuries: Consensus of Chinese experts part II: Graft selection and clinical outcome evaluation.

Lesions of the long head of the biceps tendon are commonly associated with shoulder pain and functional impairment. Surgical treatment through tenodesis has proven to be effective, but there is no consensus on the optimal technique. In this study, we present an all-arthroscopic biceps tenodesis technique inspired by the Chinese knot. This technique is relatively simple for experienced arthroscopic surgeons and has a short learning curve. It provides superior gripping strength to the biceps tendon through a double-locking suture loop, restoring its length-tension relationship.
