Composite coatings composed of carbonated calcium deficient hydroxyapatite (CDHA) and polylactic acid (PLA) were deposited on a PLA substrate surface via electrospraying. The operation parameters, structural properties, bioactivity, cell adhesion, and growth capability of as-fabricated PLA/CDHA coatings were investigated. The composite coating showed good biocompatibility and bioactivity. The deposited coating was also applied as a carrier to assist alendronate sodium (AS) local release. AS, an approved bisphosphonate drug used for the treatment of osteoporosis, was incorporated into a composite coating matrix via coelectrospraying. Its release behavior showed a long-term sustained release. This approach can be a potential coating technique for the surface modification of biopolymer implants.

3D printing is an additive manufacturing (AM) technology that has developed rapidly in the past decades due to its advantages, such as freedom of design, mass customization, waste minimization, and the ability to manufacture complex structures, as well as fast prototyping. Various materials are used in 3D printing, including metals, polymers, ceramics, concrete, and their composites. The polymer's easy processing makes it stands out among many materials. As a thermoplastic polymer, polylactic acid (PLA) received more attention as an effective biomedical material due to its proven biodegradation and biocompatibility. Herein, the development of 3D-printing technology is summarized and various applications of 3D-printed PLA and their composites in orthopedics are introduced. Furthermore, the current limitations and future opportunities in 3D printing are also discussed to help guide the 3D-printing development and improve 3D-printing strategies in orthopedic.

Background Anterior cruciate ligament (ACL) tears are frequently treated with surgical reconstruction with grafts, frequently patella tendon or hamstrings. Interference screws are often used to secure the graft in bone tunnels in the femur and tibia. This review examines whether bioabsorbable interference screws give better results than metal interference screws when used for graft fixation in ACL reconstruction. Objectives To assess the effects (benefits and harms) of bioabsorbable versus metallic interference screws for graft fixation in ACL reconstruction. Search methods We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, CENTRAL (the Cochrane Library), MEDLINE, Embase, LILACS, trial registers and reference lists of articles. Date of search: January 2016. Selection criteria We included randomised controlled trials and quasi-randomised trials comparing bioabsorbable with metallic interferences screws in ACL reconstruction. The main outcomes sought were subjective-rated knee function, failure of treatment, and activity level. Data collection and analysis At least two review authors selected eligible trials, independently assessed risk of bias, and cross-checked data. Data were pooled whenever relevant and possible. Requests for further information were sent to the original study authors. Main results We included 12 trials (11 randomised and one quasi-randomised) involving a total of 944 participants, and reporting follow-up results for 774. Participants in the 12 trials underwent ACL reconstruction with either hamstring tendon grafts (five trials) or patellar tendon grafts (seven trials). Trials participants were randomly allocated to bioabsorbable or metallic interference screws for graft fixation in Bioabsorbable versus metallic interference screws for graft fixation in anterior cruciate ligament reconstruction (Review)
