lüll The Lubinus patellofemoral arthroplasty A five- to ten-year prospective study Tauro B; Ackroyd CE; Newman JH; Shah NAJ Bone Joint Surg Br 2001[Jul]; 83 (5): 696-701We present a prospective review of the outcome of 76 Lubinus patellofemoral arthroplasties carried out in 59 patients between 1989 and 1995. At a mean follow-up of 7.5 years, 62 knees in the 48 patients were reviewed; 11 patients (14 knees) had died. None was lost to follow-up. The clinical outcome using the Bristol Knee Scoring system was satisfactory in 45% of the cases. Maltracking of the patella, resulting in lateral tilt, subluxation and polyethylene wear, was the most common complication (32%). Revision surgery was carried out in 21 knees (28%) giving a cumulative survival rate of 65% (confidence interval (CI) 49 to 77) at eight years. The survival rate for revision and moderate pain was 48% (CI 36 to 59) at six years. Progression of arthritis was seen in seven cases (9%). In five of these (6.5%), the symptoms were severe enough to need revision surgery. Due to the high proportion of unsatisfactory results, we have discontinued the use of this prosthesis.|*Knee Prosthesis[MESH]|Aged[MESH]|Aged, 80 and over[MESH]|Female[MESH]|Femur/diagnostic imaging/*surgery[MESH]|Follow-Up Studies[MESH]|Humans[MESH]|Knee Injuries/diagnostic imaging/mortality/*surgery[MESH]|Male[MESH]|Middle Aged[MESH]|Osteoarthritis, Knee/diagnostic imaging/mortality/*surgery[MESH]|Patella/diagnostic imaging/*surgery[MESH]|Postoperative Complications/diagnostic imaging/mortality/*surgery[MESH]|Prosthesis Design[MESH]|Prosthesis Failure[MESH]|Radiography[MESH]|Reoperation[MESH]|Survival Rate[MESH] |
