Introduction: The field of cartilage repair continues to advance after cell based and single-stage chondrocyte transplantation technologies. These strategies have been widely used in developed countries, and clinical, histologic and functional outcomes are of special interest.
Objective: To describe evidence of cartilage repair techniques by means of a literature review.
Results And Discussion: Cartilage restoration through osteochondral allografting or autologous chondrocyte implantation (ACI) had proven efficacy, but technical and biologic limitations to these procedures exist. However, newer second-generation and third-generation cell-based technologies are being developed and tested clinically with purposes of decreasing operative morbidity, the ability to use a single-stage approach, and improve the viability and durability of cartilage repair tissue. These techniques can be used for treatment of important chondral defects in young patients and elite athletes, but well-designed randomized clinical trials should be done to confirm the value of these procedures.

Femoroacetabular impingement syndrome (FAIS) is a common condition of the hip that can cause significant damage to the joint, leading to degeneration and osteoarthritis. FAIS constitutes an abnormal and dynamic contact between the femoral head-neck junction and the acetabular rim, resulting from altered bone morphology at one or both sites. Repetitive trauma at the site of impingement generates progressive damage to the acetabular labrum, chondrolabral junction, and articular cartilage.

Intraoperative assessment of labral quality determines arthroscopic repair versus reconstruction for hip labral tear treatment. T2 mapping technology discriminates between healthy and damaged cartilage. This study investigated if T2 mapping magnetic resonance imaging (MRI) can preoperatively predict labral repair versus reconstruction.

Due to its unique structure, articular cartilage has limited self-repair capacity. Microtissues are tiny tissue clusters that can mimic the function of target organs or tissues. Using cells alone for microtissue construction often results in the formation of necrotic cores.

Objective: Osteoarthritis, a degenerative joint disease, requires innovative therapies due to the limited ability of cartilage to regenerate. Since mesenchymal stem cells (MSCs) provide a cell source for chondrogenic cells, we hypothesize that chemicals capable of enhancing the chondrogenic potential of MSCs with transforming growth factor-beta (TGFβ) in vitro may similarly promote chondrogenesis in articular cartilage in vivo.
Design: Chemical compounds that enhance the TGFβ signaling for chondrogenesis were investigated utilizing mesenchymal stem cells derived from human induced pluripotent stem cells.

Background: Full-thickness cartilage defects have a significant impact on the function of joints in young adults, and the treatment of cartilage defects has been a challenge, as cartilage tissue is an avascular tissue. This study aimed to compare the clinical and radiological outcomes of Biphasic Cartilage Repair Implant (BiCRI) and microfracture treatments for knee cartilage defects.
Methods: This randomized controlled clinical trial enrolled patients with symptomatic knee chondral lesions smaller than 3 cm.
