Anterior cruciate ligament (ACL) injury is the common ligamentous injury of the knees. An ACL reconstruction is the procedure that has been proven to improve knee stability and functional outcomes and may prevent the osteoarthritic changes and subsequent meniscal injuries. The ACL reconstruction techniques have been developed in various ways. Anatomical single-bundle ACL reconstruction with remnant augmentation technique is the optimal reconstruction procedure. It may improve the clinical outcomes of biological healing, preserve the proprioceptive function, and has shown less tibial tunnel widening postoperatively. This chapter presents the step-by-step technique of an anatomical single-bundle ACL reconstruction, indication and contraindication for surgery, the preferred graft choice, fixation methods, pearls and pitfalls of the procedure, and postoperative rehabilitation. The review of literatures about the remnant preserving ACL reconstruction is also discussed in this chapter.

Internal snapping hip syndrome or coxa saltans interna results from the iliopsoas tendon snapping over the superior pubic ramus, iliopectineal eminence, anterior hip joint, femoral head or the lesser trochanter. This condition occurs in either the native hip or a prosthetic hip joint. Conservative management is the mainstay treatment, but iliopsoas release continues to be the definitive treatment in patients with failed conservative measures. The arthroscopic iliopsoas release from the central or peripheral compartment is useful in the management of internal snapping syndrome and may have less hip flexion strength deficits postoperatively as compared to the releasing from the lesser trochanteric level. Endoscopic iliopsoas release at the lesser trochanter level is the preferred operative treatment option for internal snapping patients who have undergone a total hip replacement.
