The Oxford Total Meniscal Knee (TMK by Biomet), is a total knee replacement with a multidirectional mobile bearing. As part of the evaluation of the TMK we compared our group of TMK knee replacements with an equivalent cohort of AGC total knee replacements. Patients recruited to AGC trial from 1994 to 2001. 254 AGC knee replacements sequentially recruited in 210 patients. Patients recruited to TMK trial from 2001 to 2007. 221 TMK knee replacements sequentially recruited in 193 patients. Patients prospectively randomised to having uncemented HA coated (HAC) or cemented versions in both groups. Each patient was reviewed pre-operatively, at 6 weeks, 6 months, 1 year and then annually. All AGC & TMK TKR's were assessed clinically using HSS scores and radiographically. TMK group also assessed using AKSS and OKQ scores.Introduction
Methods
Debate continues regarding the relative advantages of ceramic-on-ceramic (CoC) and metal-on-polyethylene (MoP) articulations in total hip arthroplasty (THA). Perceived benefits of CoC include longevity, and low wear - in turn limiting the effects of particulate wear debris. However, CoC bearings cost significantly more, and concern remains over the risk of ceramic fracture; a complication not seen with MoP bearings, which are also cheaper. We electronically randomised 268 consecutive patients undergoing THA to receive either a CoC or MoP articulation. Patients aged over 72 were excluded. In all patients the prosthesis used was an uncemented ABG II (Stryker, USA), implanted by one of the two senior authors (HDA, ABM). Patients were scored preoperatively, and at annual follow-up clinics, using SF36, Visual Analogue (VAS), Merle d'Aubigné (MD) and Oxford Hip (OHS) Scores. Satisfaction levels were also documented.Introduction
