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

One-step cartilage repair of full-thickness chondral defects in the knee using an HA-BMAC led to successful long-term clinical outcomes and maintenance of joint junction after a mean follow-up duration of 14 years. Long-term clinical success in active, nonobese patients has been uniformly demonstrated across a wide range of patient ages and lesion types, including cases of multicompartment involvement, treatment of associated conditions, and large or bipolar chondral lesions.
