- The role of psychological processes in team sports has been studied extensively. The chapter focuses on the psychological factors that are unique to basketball. These factors include the following: (a) free throw shooting—examining the role of gaze behavior in enhancing shooting percentages, (b) “the hot hand”—the underlying mechanisms leading to a “hot streak,” (c) clutch performance under pressure—why some players choke in critical game situations while others flourish, and (d) team decision-making—team performance as a unit which operates with optimal coordination and communication. This chapter consists of research findings and theoretical insights to capture the mechanisms leading to enhanced psychological skills and expert performance. Furthermore, this chapter provides guidelines for improving performance by transferring the knowledge gained from research to the applied domain. General psychological skills such as preperformance routine, decision-making, and attention are examined throughout the chapter. A final summary of findings including limitations in the current literature and future directions to enhance the domain are provided.

- Currently both autograft and allograft tissues are available for reconstruction of posterior cruciate, collateral and multi-ligament knee injuries. Decision-making is based on a complex interplay between anatomical structures, functional bundles and varying biomechanical requirements. Despite theoretically better biological healing and reduced risk of disease transmission autografts are associated with donor site morbidity as well as being limited by size and quantity. The use of allografts eliminates donor-site morbidity but raises cost and issues of clinical effectiveness. The purpose of this paper is to review current concepts and evidence for the use of allografts in primary posterior cruciate, collateral and multi-ligament reconstructions.A narrative review of the relevant literature was conducted for PCL, collateral ligament and multi-ligament knee reconstruction. Studies were identified using a targeted and systematic search with focus on recent comparative studies and all clinical systematic reviews and meta-analyses. The rationale and principles of management underpinning the role of allograft tissue were identified and the clinical and functional outcomes were analysed. Finally, the position of postoperative physiotherapy and rehabilitation was identified.The review demonstrated paucity in high quality and up-to-date results addressing the issue especially on collaterals and multi-ligament reconstructions. There was no significant evidence of superiority of a graft type over another for PCL reconstruction. Contemporary principles in the management of posterolateral corner, MCL and multi-ligament injuries support the use of allograft tissue.The present review demonstrates equivalent clinical results with the use of autografts or allografts. It remains, however, difficult to generate a conclusive evidence-based approach due to the paucity of high-level research. When confronted by the need for combined reconstructions with multiple grafts, preservation of synergistic muscles, and adapted postoperative rehabilitation; the current evidence does offer support for the use of allograft tissue.IV.
