Three-dimensional (3D) printing is a low-cost, high-efficiency production method, which can reduce the current cost and increase the profitability of skin repair material industry nowadays, and develop products with better performance. The 3D printing technology commonly used in the preparation of skin repair materials includes fused deposition molding technology and 3D bioprinting technology. Fused deposition molding technology has the advantages of simple and light equipment, but insufficient material selection. 3D bioprinting technology has more materials to choose from, but the equipment is cumbersome and expensive. In recent years, research on both technologies has focused on the development and application of materials. This article details the principles of fused deposition modeling and 3D bioprinting, research advances in wound dressings and tissue engineering skin production, and future developments in 3D printing on skin tissue repair, including cosmetic restoration and biomimetic tissue engineering. Also, this review prospects the development of 3D printing technology in skin tissue repairment.

ObjectiveTo explore the effectiveness of keystone flap in repairing skin and soft tissue defects around joint.MethodsBetween March 2013 and December 2017, 10 patients of skin and soft tissue defects around the joint were repaired with keystone flaps. There were 6 males and 4 females. The age ranged from 17 to 72 years, with an average age of 57.5 years. The skin and soft tissue defects located around the joints, including 2 cases of hip joints, 4 cases of knee joints, 3 cases of elbow joints, and 1 case of wrist joint. The cause of skin and soft tissue defects included scar contracture in 3 cases, basal cell carcinoma in 3 cases, squamous-cell carcinoma in 3 cases, and dermatofibrosarcoma protuberant in 1 case. The area of defects ranged from 4 cm×3 cm to 11 cm×11 cm. The keystone flap was designed beside the wound, and the V-shaped flap was designed at the longer side of the fan-shaped flap. The area of flap ranged from 7 cm×3 cm to 35 cm×10 cm. The flap was constantly compressed by vacuum assisted closure after operation for 3-6 days.ResultsPrimary wound healing was achieved and the flaps survived. All patients were followed up 6-24 months (mean, 15 months). The texture and color of flap was similar to the adjacent area. The appearance and function of joint were satisfactory.ConclusionThe keystone flap is a feasible and efficient way to repair the wound around joint. Furthermore, the skin color and texture is similar to the surrounding tissue after healing.
Objective To explore the feasibility and effectiveness of using the superior lateral genicular artery (SLGA) perforator propeller flap to reconstruct soft-tissue defects around the knee joint. Methods Between October 2013 and May 2019, 10 patients underwent repairing of soft-tissue defects around the knee joint using the SLGA perforator propeller flap. There were 6 males and 4 males, with a median age of 34.5 years (range, 6-66 years). Etiologies included radical tumor resection in 4 cases, post-burn scar contracture in 3 cases, post-burn hypertrophic scar in 2 cases, and prothesis exposure after knee arthroplasty in 1 case. Defects located on the lateral knee in 6 cases, proximal lateral leg in 2 cases, popliteal fossa in 1 cases, and infrapatellar region in 1 case. The size of soft-tissue defects was from 6 cm×4 cm to 14 cm×8 cm. The extraction range of the flap was from 10.0 cm×5.5 cm to 23.0 cm×7.0 cm; the length of the perforator pedicle was 2.5-5.0 cm, with an average of 3.65 cm; the flaps were rotated 180°, the large paddle of the propeller flap was used to repair the defect, and the small paddle was used to assist the closure of donor site. Results Blister was observed in the distal 3-cm of one flap and the flap survived after conservative management. All the flaps survived, and the wounds in the donor and recipient areas healed by first intention. There was no vascular crisis, incision dehiscence, infection, or other complications. All 10 patients were followed up 4 to 48 months, with an average of 12.6 months. The color and texture of the flap were similar to those of the recipient area, and there was no need for secondary operation for degreasing and thinning. Scar contracture was corrected; no tumor recurrence was found in tumor patients; the artificial knee joint was preserved, the knee joint flexion and extension activities were good, and all the patient and family members were satisfied with the appearance and function of the lower limbs after operation. Conclusion The SLGA perforator propeller flap surgery is relatively simple without the need of microvascular anastomosis, has the minimal donor-site morbidities, and can provide a compound flap for the repairing of a complex wound. The SLGA perforator propeller flap is one of the optional methods to repair soft-tissue defects around the knee joint.
