160 degree angle. The purpose of this study is to evaluate the clinical result of the LPS MobileFlex knee.MATERIALS AND METHODS .From January 1999 to February 200, 1043 (one thousand and forty three) surgeries wereperformed on patients treated for advanced osteoarthritis. All the surgeries were carried out bythe same surgeon. The majority of the patients had bilateral total knee replacementssimultaneously .Mobile and fixed implants were used. Pre-operative ranges of motion weredocumented on lateral x-ray. Patients were considered to have full flexion if they were able toflex the knee to at least 140 degree and sit on the ground with calf touching thigh for at leastone minute. Data were processed at University of DundeeRESULTS67% obtained full flexion as defined above. The majority of the cases with full flexion hadfull movement pre-operatively; except for 63 cases .Average range of motion was much betterthan University of Dundee data base. Complications included; 2 cases of peroneal nerve palsy,three of dislocation, and two of infection, a case of rupture of MCL ligament, a case of intraoperativetibial plateau fracture, 2of supracondylar femur fracture and 4 patella clunckCONCLUSIONThe LPS Flex Implant had a similar complication rate to those reported by other series. Therewas no complication that could be specifically attributed to deep flexion. However it should bestressed that this exceptional result has to do mainly with careful patient selection.Friday, October 8, 2010, 8:40-9:30Session A11: Knee Arthroplasty in the Middle EastINTRODUCTIONClinical Experience With Mobile Lps Flex Implant*Ibrahim Gado - American Hospital - Dubai, UAE*Email: ibrahim.gado@yahoo.comThe majority of implants available in the market today were designed to allow for a flexion upto 130 degree angle.
