Background: The purpose of this study was to clarify the difference in ligamentization between the remnant-preserving (RP) and remnant-sacrificing (RS) techniques in anterior cruciate ligament (ACL) reconstruction using magnetic resonance imaging (MRI).
Methods: A retrospective comparative study was carried out on 98 patients undergoing ACL reconstruction using either an RP (n=56) or RS (n=42) technique. MRI was performed at one of four time points postoperatively, and the signal intensity of the ACL graft was analyzed using the signal to noise quotient (SNQ) ratio and inter-bundle high signal intensity, along with an analysis of the survival rate of remnant tissue.
Results: The mean SNQ ratio of grafted tendons in the RP group was significantly higher than that seen in the RS group in the proximal and middle regions two to four months after surgery (P<0.05) and was significantly lower than that seen in the RS group in all regions at 12 -18months (P<0.05). The inter-bundle high signal intensity was observed more frequently in the RP group (73.7%) at two to four months. Tibial remnants were observed on postoperative MRI regardless of when MRI was conducted.
Conclusion: The ACL graft of the RP group showed higher signal intensity in the early stage and lower signal intensity in the late stage compared to that of the RS group. The ligamentization of grafts in the RP group proceeded more quickly. Preserving the remnant in ACL reconstruction appears to have a positive effect on ligamentization.

Backgrounds: Osteoarthritis (OA) significantly impacts the elderly, leading to disability and decreased quality of life. While hyaluronic acid (HA) and chondroitin sulfate (CS) are recognized for their therapeutic potential in OA, their effects on extracellular matrix (ECM) degradation are not well understood. This study investigates the impact of HA and CS, individually and combined, on ECM degradation in OA and the underlying mechanisms.

Post-traumatic osteoarthritis (PTOA) is a painful joint disease characterized by the degradation of bone, cartilage, and other connective tissues in the joint. PTOA is initiated by trauma to joint-stabilizing tissues, such as the anterior cruciate ligament, medial meniscus, or by intra-articular fractures. In humans, ~50% of joint injuries progress to PTOA, while the rest spontaneously resolve.

Objectives: The primary repair of the anterior cruciate ligament (ACL) has re-emerged as a treatment for acute ruptures. While numerous studies have investigated rehabilitation after ACL reconstruction, few have focused on primary repair. We aimed to describe the rehabilitation protocols for primary ACL repair, and to identify knowledge gaps and differences between primary ACL repair and reconstruction.

Basketball is an intense, fast-paced game that is physically, highly demanding. Certain aspects of the game, such as the quick pivoting and cutting movements, predispose the players to serious knee injuries, including anterior cruciate ligament (ACL) tears. While an ACL tear can be a devastating condition for players, multidisciplinary management of the injury can provide the players with a reasonable chance to return to play at the pre-injury level.

Importance: Patients with arthritis and ruptured cruciate ligaments typically require surgery. Following surgery, it is necessary to improve joint function in early stage.
Objective: This study aimed to investigate the impact of intraoperative intra-articular injection of the ELHLD peptide (L-glutamyl-L-leucyl-L-histidyl-L-leucyl-L-aspartic acid) on postoperative stifle function in patients with medial patella luxation grade 3 and osteoarthritis grade 2 undergoing tibial plateau leveling osteotomy due to anterior cruciate ligament (ACL) rupture.
