C-X-C motif chemokine ligand 12 (CXCL12), often referred to as stromal cell-derived factor 1 (SDF-1), is a crucial factor for musculoskeletal biology. SDF-1 is a powerful chemokine that has been shown to have a significant impact on a variety of physiological functions, including tissue repair, homeostasis maintenance, and embryonic development. SDF-1 plays a dominant role in bone and cartilage metabolism. It directs mesenchymal stem cell migration, controls osteogenesis and chondrogenesis, promotes angiogenesis, and modifies the inflammatory environment. SDF-1 also acts as an inflammatory chemokine during joint inflammation, recruiting inflammatory mediators to act and cause bone and cartilage degradation, thus causing osteoarthritis. Age-related bone loss and osteoporosis is exacerbated by SDF-1, which is elevated in the peripheral circulation due to a phenomenon known as "senescence associated secretory phenotype" of SDF-1. SDF-1 is also implicated in cancer metastasis causing the spread of secondary malignancies. Thus, the aim of this review is to explore the complex methods by which SDF-1 affects the fine equilibrium of bone and cartilage metabolism, providing insight into its importance in both healthy and diseased conditions.

Ochronotic arthropathy: skeletal manifestations and orthopaedic treatment.
EFORT Open Rev
February 2025
Alkaptonuria is an extremely rare disorder of tyrosine metabolism caused by an autosomal recessive enzymatic deficiency of homogentisic acid (HGA) oxidase, causing its accumulation in collagenous structures, especially in hyaline cartilage. It is characterized by a triad of homogentisic aciduria, bluish-black discoloration of connective tissues (ochronosis) and arthropathy of the spine and large weight-bearing joints. Several clinical manifestations were described including coronary and valvular calcification, aortic stenosis, limited chest expansion, and renal, urethral and prostate calculi as well as ocular and cutaneous pigmentation.

ObjectiveAim of this study was to evaluate the 24 months follow-up data of the German Cartilage Registry (KnorpelRegister DGOU, GCR) regarding the influence of body mass index (BMI) on clinical outcomes after surgical osteochondral lesions of the talus (OCT) treatment.DesignA total of 303 patients met the inclusion criteria. Pre- and post-operative Foot and Ankle Outcome Score (FAOS) total scores, subscores, and ΔFAOS were analyzed for most frequent surgical techniques (bone marrow stimulation [BMS], matrix-augmented BMS, matrix-augmented BMS with additional bone grafting) in normal weight group (NW, BMI <30 kg/m, = 228) and obese weight group (OW, BMI ≥30 kg/m, = 75).

Introduction: Costochondral grafting is well-known reconstructive option for the temporomandibular joint. In the upper extremity, non-vascularized costochondral grafts have been used for radial head reconstruction, for osteoarthritis of the trapeziometacarpal joint and proximal pole reconstruction of the scaphoid. Evidence suggests that vascularization of bone grafts lead to a higher union rate and a faster time to union.

Background: Low back pain(LBP) is very common among the population, and intervertebral disc(IVD) degeneration is considered to be the most common cause of LBP, but the pathophysiological process between IVD degeneration and LBP is not very clear. We conducted this study to clarify the interplay between quantitative magnetic resonance imaging (MRI) parameters, including q-Dixon and T2 mapping, and clinical symptomatology in patients with LBP.
Methods: All LBP patients underwent lumbar spine MRI, encompassing q-Dixon and T2 mapping.
