NCT04234412

Brief Summary

The purpose of this study is to evaluate the clinical results after implantation of human umbilical cord blood-derived mesenchymal stem cells(hUCB-MSCs) and High tibia osteotomy in patients with medial compartment osteoarthritis(MCOA) as well as varus deformity of the knee joint. This study will prospectively evaluate 10 knees after hUCB-MSCs implantation and High Tibial Osteotomy(HTO) in the medial compartment osteoarthritis and varus deformity of the knee joint. Clinical outcomes will be evaluated using the International Knee Documentation committee(IKDC), Visual analogue scale(VAS), Western Ontario and McMaster Universities Arthritis Index(WOMAC), and patients satisfaction with the surgery.

Study Arms (1)

Osteoarthritic knee patients

EXPERIMENTAL

Osteoarthritic Knee of the patients who will be treated wth high tibial osteotomy and implantation of allogenic human umbilical cord blood-derived stem cells.

Procedure: umbilical cord blood stem cell implantation for osteoarthritis treatment

Interventions

The arthroscopic procedure is performed in the supine position after spinal anesthesia. Once the chondral lesion is identified through a standard anteromedial and lateral portal, meniscectomy, meniscal repair, and lateral retinacular release are performed if necessary. microfracture is performed using a microfracture awl. Once both the unstable cartilage and subchondral bone are removed in the lesion area and the sclerotic bone is peeled slightly by using a burr, hole(s) are created for implantation by using a drill bit(diameter 4; depth: 4mm). After implantation is performed in the hole by injecting the mixture of sodium hyaluronate and hUCB-MSCs, it is trimmed to the height of the surrounding articular surface.
