Pain and other short- and long-term sequelae of irreparable meniscal tears remain a challenge for the orthopedic community, and there is a genuine need for an approach which will offer patients and surgeons new acceptable treatment options (Gilbert and Ashwood, Trauma 9:189–194, 2007).

Orteq Ltd. (London, UK) has developed a polyurethane scaffold, Actifit® (Welsing et al., Am J Sports Med 36:1978-1989, 2008), for blood vessel ingrowth and meniscal tissue regeneration (Tienen et al., Am J Sports Med 34:64-71, 2006) intended for the treatment of irreparable, painful meniscus tears and meniscal tissue defects. It is available in the medial and lateral configurations (Fig. 1). Criteria for use include an intact meniscal rim and sufficient tissue in the anterior and posterior horns to permit fixation of the scaffold. Other requirements include a well-aligned and stable knee joint, an ICRS classification grade ≤3, a body mass index <35 kg/m2, and the non-presence of systemic disease or infection sequelae (Arnosky andWarren, Am J Sports Med 10:90–95, 1982).
