Arthroscopic Bone Grafting of Deep Acetabular Cysts Using a Curved Delivery Device

Acetabular intraosseous cysts are frequently encountered in patients with dysplasia or femoroacetabular impingement. Small cysts are typically addressed by removing the cyst lining and stimulating healing via microfracture or abrasion chondroplasty. In contrast, larger cysts involving 1-3 cm3 frequently require additional fortification with bone graft material to facilitate osseous ingrowth and cyst healing. Previous arthroscopic reports have described the use of rim trimming to access the extra-articular side of the cyst, with subsequent use of straight metal cannulas for delivery of bone graft material. The downsides of this technique include the requirement for rim trimming, which may be ill advised in patients with normal coverage or dysplasia, as well as the creation of a second breach in the cyst wall, precluding pressurization of the bone graft material. We describe an arthroscopic technique using a curved delivery device allowing for deeper penetration into the cyst cavity through the articular side and greater delivery of bone graft material

All-Arthroscopic Ligamentum Teres Reconstruction With Graft Fixation at the Femoral Head-Neck Junction

Ligamentum teres (LT) tears are increasingly being recognized as a source of pain and dysfunction in the hip. Although debridement for partial tears of the LT has long been established as the standard of care with good pain relief, reconstruction has been successfully performed in select patients to address concerns of persistent symptomatic instability. The current technique for femoral tunnel preparation carries the added morbidity of open dissection in the peritrochanteric space, an unnecessarily long tunnel with excessive bone removal, and a need for a very long graft due to distal fixation at the lateral femoral cortex. To address these shortcomings, we present a technique for arthroscopic femoral tunnel drilling at the level of the head-neck junction, allowing for an all-arthroscopic LT reconstruction
