OVERVIEW Chapter synopsis Osteonecrosis (ON) of the knee is a condition that can rapidly lead to end-stage osteoarthritis. It can be classified as primary, secondary, or post-arthroscopic. Surgical options include arthroscopy, core decompression, osteochondral grafting, re-alignment osteotomies, and prosthetic arthroplasty.…
OVERVIEW Chapter synopsis Osteochondritis dissecans (OCD) is a pathologic process that results in the detachment of subchondral bone and its overlying articular cartilage from the underlying bone. Several options are available to treat adult OCD, including debridement, drilling, loose body…
Overview Chapter synopsis Efforts should be made to preserve the meniscus, but if this is not possible, meniscus regeneration with biologic or synthetic scaffolds may be an option. Multicenter clinical trials and reports have demonstrated new tissue formation and fewer…
OVERVIEW Chapter synopsis In this chapter, the different options for meniscus substitution are discussed and elaborated. Specific attention is paid to the important differences in indication and surgical technique. Although a number of these therapeutic options have already proven their…
OVERVIEW Chapter synopsis Arthroscopic meniscal allograft transplantation (MAT) has the potential to relieve pain and increase knee function within a subset of patients with non-functional menisci or after subtotal or total meniscectomy. The arthroscopic bone plug technique allows a surgeon…
OVERVIEW Chapter synopsis Meniscal allografts have been shown to provide subjective benefits in symptomatic patients after meniscectomy. Various surgical techniques have been described, but basic science studies have shown that maintenance of the horn attachments with bone may provide superior…
OVERVIEW Chapter synopsis This chapter summarizes the indications, technique, and results of meniscal allograft transplantation with the bridge-in-slot technique for the treatment of symptomatic meniscal deficiency. Important points Meniscal transplants are indicated for symptomatic compartment overload caused by total or…
OVERVIEW Chapter synopsis Meniscal root tears result in a dysfunctional meniscus that is associated with rapid degenerative changes within the compartment due to increased stress on the cartilage and bone. Repair of meniscal root tears in the appropriate clinical setting…
OVERVIEW Chapter synopsis All-inside meniscal repair offers many advantages over traditional inside-out or outside-in meniscal repairs. Benefits include decreased operative times, avoidance of the risks associated with secondary incisions, and ease of use of the implants. Implant designs have evolved…
OVERVIEW Chapter synopsis The outside-in technique of meniscus repair is useful for treating tears amenable to repair within the anterior horn and body. As our understanding of the biomechanical consequences of meniscal deficiency has improved, a detailed understanding of this…
