“…Furthermore, although revision of any of the components is the most objective and commonly cited endpoint for the study of joint replacement, it has been criticised for having a low sensitivity for the detection of clinically significant failure. 26 Our study confirms the findings of a previous report that the BOX TAR has an acceptable mid-term survival rate. 2 Patients were found to have a good functional outcome, although additional surgical procedures were sometimes needed.…”

The Bologna-Oxford (BOX) total ankle replacement (TAR) was developed with the aim of achieving satisfactory pain-free movement of the ankle. To date, only one single multicentre study has reported its clinical results. The aim of this study was to conduct an independent review of its mid-term results. We retrospectively reviewed a total of 60 prospectively followed patients in whom 62 BOX TARs had been implanted between 2004 and 2008. We used the American Orthopedic Foot and Ankle Society (AOFAS) score to assess the clinical results. Standardised radiographs taken at the time of final follow-up were analysed by two observers. The overall survival was 91.9% at a mean follow-up of 42.5 months (24 to 71). The mean AOFAS score had improved from 35.1 points (sd 16.6; 4 to 73) pre-operatively to 78.0 (sd 10.7; 57 to 100) at final follow-up (p < 0.01). Tibial radiolucencies < 2 mm in width were seen around 16 TARs. Talar radiolucencies < 2 mm were seen around four TARs. A total of 47 patients (78.3%) were very satisfied or satisfied with the outcome. Five patients required revision for functional limitation or continuing pain.

“…Characteristic radiologic changes associated with the degeneration of cartilage include narrowing of the joint space; subchondral sclerosis; and the appearance of osteophytes, intraarticular osteochondral bodies, bone marrow edema, and subchondral cysts. Although the latter are associated with osteoarthritis, they can develop as primary lesions independent of it [1].…”

“…This high pressure could act not only to force synovial fluid into a subchondral cyst (Crawford et al 1998), but also to disturb the subchondral bone circulation, leading to ischaemia and fibrosis in bone and bone marrow around OA cysts. It has been shown that the intracapsular pressure is higher in hip joints containing loose prosthetic components; this increased pressure may pump wear particles along the bone-implant interface where osteolysis occurs (Robertsson et al 1997).…”
