Focal chondral lesions in the adolescent population create a particular challenge for orthopedic surgeons, and currently there exists no consensus on proper treatment. Numerous techniques for addressing focal chondral defects are employed in both pediatrics and adults, including fragment excision, debridement and fixation, bone marrow stimulation and microfracture techniques, cell-based options, as well as chondral and osteochondral grafts. Although historical evidence is mixed, recent reports of primary fixation of displaced cartilage fragments have shown favorable results. We present a case of reduction and fixation of a large displaced cartilage lesion in an elite young tennis player. Our results, in addition to other reports mentioned in this manuscript, highlight the importance of considering primary fixation of large chondral lesions when amenable to repair.

One-Step Cartilage Repair of Full-Thickness Knee Chondral Lesions Using a Hyaluronic Acid-Based Scaffold Embedded With Bone Marrow Aspirate Concentrate: Long-term Outcomes After Mean Follow-up Duration of 14 Years.

Background: One-step cell-based techniques of cartilage repair that lead to restoration of durable chondral tissue and long-term maintenance of joint function are cost-effective and ideal for routine use.
Purposes: To examine the long-term clinical outcomes, after a mean follow-up duration of 14 years, of cartilage repair in the knee using a hyaluronic acid-based scaffold in association with bone marrow aspirate concentrate (HA-BMAC) and to evaluate the effect of age, lesion characteristics, and associated treatments on the outcome of this cartilage repair method.
Study Design: Case series; Level of evidence, 4.
Article Synopsis
- The study evaluated the long-term outcomes of knee microfracture procedures, focusing on clinical, radiographic, and patient-reported results after a mean follow-up of 10 years or more.
- Researchers analyzed nine studies involving 727 patients, revealing that 40%-48% experienced osteoarthritis progression, while patient-reported outcomes showed significant improvements post-surgery.
- The return-to-sport rate was low, between 17.2% and 20%, indicating declining clinical outcomes over time, with noticeable variability in definitions of failure and reoperation rates among the studies.
Comparison study on hyaline cartilage versus fibrocartilage formation in a pig model by using 3D-bioprinted hydrogel and hybrid constructs.

Article Synopsis
- Cartilage tissue engineering (CTE) aims to regenerate hyaline cartilage, with this study comparing the formation of hyaline versus fibrocartilage in a pig model using 3D bioprinted constructs (hydrogel and hybrid).
- The constructs were made from a bioink containing alginate and chondrogenic cells, with the hybrid version incorporating polycaprolactone strands for added support under biomechanical stress.
- Results indicated that both constructs improved cartilage formation over time, with hydrogel constructs showing superior results at both one and three months post-implantation compared to hybrid constructs.
Background: Particulated autograft cartilage implantation is a surgical technique that has been previously described for the repair of osteochondral lesions of the talus (OLT). It uses cartilage fragments harvested from the OLT that are minced into 1-2-mm fragments and then immediately reimplanted back into the chondral defect and sealed with fibrin glue during a single-stage surgery. The purpose of this study was to characterize the suitability of these minced cartilage fragments as immediate autograft for the treatment of OLTs.

Recent research shows arthroscopic debridement with preservation of the subchondral bone plate shows superior results compared with microfracture. The results of microfracture can be unpredictable, largely because of the formation of fibrocartilage, which lacks the durability of hyaline cartilage.
