Abstract
The effective repair of bone defects has long been a major challenge in clinical practice. Currently, research efforts mostly focus on achieving sufficiently good bone repair, with little attention paid to achieving both good and fast repair. However, achieving highly efficient (H-efficient) bone repair, which is both good and fast, can shorten the treatment cycle and facilitate rapid patient recovery. Therefore, the development of a H-efficient bone repair material is of significant importance. This study incorporated the previously developed osteoinductive photothermal agent (PTA) BPICT into printing paste to prepare a near-infrared (NIR)-responsive BPICT scaffold. Subsequently, the effects of photothermal therapy (PTT) on bone repair and drug release were assessed in vitro. To further validate the H-efficient bone repair properties of the BPICT scaffold, the scaffold was implanted into bone defects and its ability to promote bone repair in vivo was evaluated through radiology and histopathological analysis. The results indicated that compared to scaffolds containing only Icaritin (ICT), the BPICT scaffold can achieve PTT to promote bone repair through NIR irradiation, while also enabling the controlled release of ICT from the scaffold to enhance bone repair. Within the same observation period, the BPICT scaffold achieves more efficient bone repair than the ICT scaffold, significantly shortening the bone repair cycle while ensuring the effectiveness of bone repair. Therefore, the NIR-responsive scaffold based on PTT-mediated controlled release of bone growth factors represents a feasible solution for promoting H-efficient bone repair in the area of bone defects.

Abstract
Photothermal therapy is a promising approach to cancer treatment. The energy generated by the photothermal effect can effectively inhibit the growth of cancer cells without harming normal tissues, while the right amount of heat can also promote cell proliferation and accelerate tissue regeneration. Various nanomaterials have recently been used as photothermal agents (PTAs). The photothermal composite scaffolds can be obtained by introducing PTAs into bone tissue engineering (BTE) scaffolds, which produces a photothermal effect that can be used to ablate bone cancer with subsequent further use of the scaffold as a support to repair the bone defects created by ablation of osteosarcoma. Osteosarcoma is the most common among primary bone malignancies. However, a review of the efficacy of different types of photothermal composite scaffolds in osteosarcoma is lacking. This article first introduces the common PTAs, BTE materials, and preparation methods and then systematically summarizes the development of photothermal composite scaffolds. It would provide a useful reference for the combination of tumor therapy and tissue engineering in bone tumor-related diseases and complex diseases. It will also be valuable for advancing the clinical applications of photothermal composite scaffolds.

Abstract
Malignant bone tumors are characterized by severe disability rate, mortality rate, and heavy recurrence rate owing to the complex pathogenesis and insidious disease progression, which seriously affect the terminal quality of patients' lives. Photothermal therapy (PTT) has emerged as an attractive adjunctive treatment offering prominent hyperthermal therapeutic effects to enhance the effectiveness of surgical treatment and avoid recurrence. Simultaneously, various advanced biomaterials with photothermal capacity are currently created to address malignant bone tumors, performing distinctive biological functions, including nanomaterials, bioceramics (BC), polymers, and hydrogels et al. Furthermore, PTT-related combination therapeutic strategies can provide more significant curative benefits by reducing drug toxicity, improving tumor-killing efficiency, stimulating anti-cancer immunity, and improving immune sensitivity relative to monotherapy, even in complex tumor microenvironments (TME). This review summarizes the current advanced biomaterials applicable in PTT and relevant combination therapies on malignant bone tumors for the first time. The multiple choices of advanced biomaterials, treatment methods, and new prospects for future research in treating malignant bone tumors with PTT are generalized to provide guidance.
