We have reviewed 105 Liverpool Mark II knee replacements in 71 patients to assess survival and long-term results. Assessment was both clinical and radiological, using a modification of the British Orthopaedic Association knee function assessment chart, and analysis was by the survivorship method as advocated by Tew and Waugh. The follow-up period was between 13 and 113 months with 42 prostheses being in situ for over six years. Eight knees (7.6%) have been revised or arthrodesed because of infection or loosening, giving a cumulative success rate of 89% after seven years based on prosthesis survival alone. Of the remaining knees, 71.1% were either free of pain or caused only minimal pain. The cumulative success rate as judged by the stricter criteria of the prosthesis being in situ and causing little or no pain suggested a 50% survival between 73 and 96 months. Most patients (77.3%) were enthusiastic or satisfied with their results. Complications included deep wound infection (8.6%), and loosening which needed further surgery (11.4%).

One hundred and three sequential Stanmore knee replacements were reviewed retrospectively on two occasions with a maximal follow-up period of nine years three months. This knee prosthesis, which is hinged, was successful in alleviating pain, stabilising an unstable knee and modestly increasing the arc of flexion. Walking capacity was increased and flexion contractures were reduced. There were seven cases of infection and four of fracture around the prosthesis. All these proved difficult to treat and two knees with both fracture and infection needed amputation. Eight knees were revised for aseptic loosening and a further 14 were found to have radiological signs of loosening. The results have been analysed by the methods advocated by Tew and Waugh and give a cumulative success rate of 80 per cent at seven years, provided success is judged solely by whether the prosthesis is still in situ. The role of the Stanmore knee as a primary arthroplasty is discussed.
