We have replaced the anterior cruciate ligament in 92 patients using Dacron prostheses. There were 52 Stryker implants, 25 Leeds-Keio and 15 Proflex. The majority of the patients were active sportsmen. A similar operative technique and postoperative programme was used in each patient. Seventy patients have been re-examined, and a further 9 answered a postal questionnaire. Forty Stryker ligament repairs have been followed up for an average of 28 months; 15 had broken or were otherwise inadequate. Ten patients had symptoms and there were 4 re-operations. Of the Leeds-Keio repairs 20 have been reviewed, of which 7 were either ruptured or mechanically inadequate. Three patients had symptoms and 1 had undergone further operation. Of 14 Proflex ligaments, 1 had failed, but the patient was asymptomatic. The authors consider that the Stryker and Leeds-Keio ligaments should not be used, and that the Proflex prosthesis shows promise but requires long term assessment.
Our results suggested that computer assistance provides a more accurate alignment in TKA. The reduced incision length and hospitalization time appear as two other advantages of this technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
