One of the greatest challenges nowadays facing orthopaedic surgeons around the world is the problem of articular cartilage defects and their treatment. The autologous matrix-induced chondrogenesis technique is based on 2 elements-drilling into bones and matrix application. The purpose of this article is to present the surgical technique of arthroscopic treatment of chondral or osteochondral defects in the ankle using the autologous matrix-induced chondrogenesis technique.

Chondral and osteochondral lesions of the knee in skeletally immature patients, can result in serious long-term sequelae, such as early knee arthrosis. While there is an abundance of studies concerning chondral repair techniques, there have been relatively few studies that have examined outcomes following cartilage repair in skeletally immature patients. Therefore, we planned to answer the following question: does the AMIC® technique result in positive outcomes for the repair of cartilage lesions in the knee in adolescent patients ? Our hypothesis was that the AMIC® technique improves outcomes for skeletally immature patients with an ICRS stage III or IV osteochondral lesion two year after the surgery.

Isolated patellar chondromalacia in patients with patella alta and no history of patellar subluxations or dislocations is associated with a supratrochlear rim at the entrance to the femoral trochlea. This technical note outlines an arthroscopic technique called supratrochlear rim resection, which proposes a line of treatment that addresses not only symptoms (patellar cartilage defect) but also a suspected biomechanical reason (supratrochlear rim). The proposed technique combines resection of the supratrochlear rim with a modification of autologous matrix-induced chondrogenesis cartilage reconstruction on the femoral side at the location of the resected rim, as well as on the patellar defect.

Background: Knee femoral chondral pathology is frequently encountered during knee arthroscopies. Based on previous studies, the unaddressed, painful, poor knee function progresses into arthritis. Addressing this scenario with a simple, less invasive arthroscopic procedure may provide a simple solution for this cohort of patients.

The treatment of osteochondritis dissecans of the knee has always been a challenge for orthopedic surgeons. We present a case report of a 38-year-old male with severe right knee pain after suffering from an indirect trauma and axial rotation of the knee, limiting knee functionality and impeding his ability to walk, with a diagnosis of osteochondritis dissecans in the trochlea of the knee, who underwent arthroscopic treatment with matrix-induced autologous chondrocyte implantation (MACI). After the surgery, a physical therapy protocol for MACI was implemented, and magnetic resonance images with cartilage mapping were used to evaluate the recovery of the lesion.

Chondral and osteochondral defects of the knee are painful and disabling in the short term, can lead to accelerated osteoarthritis in the long term, and have relatively poor healing potential. Although many cartilage restoration procedures exist for focal cartilage defects, matrix-induced autologous chondrocyte implantation (MACI) for the appropriate patient has evolved as a reliable technique with encouraging long-term outcomes. Despite the reported favorable outcomes, there remains a relative dearth of literature on the use of MACI with autologous bone graft.
