@entity7502 mesh augmentation for complete XXXX after total knee arthroplasty.

@entity1 @entity7502 @entity397 @entity158 @entity121
INTRODUCTION: @entity7502 mesh has previously been shown to be an effective treatment for failed patellar tendon repairs after total knee arthroplasty (TKA), but there have been few reports of this synthetic mesh used in complete @entity397 after TKA. METHODS: We retrospectively reviewed seven consecutive cases in six @entity1 with complete @entity121 tears after TKA who had their @entity121 tendon repaired with suture and @entity7502 mesh augmentation. All but two @entity1 had previously failed primary suture repair. @entity1 outcomes were evaluated using the Knee Society Score. Standardized anterior-posterior (AP), lateral and merchant radiographs were evaluated preoperatively and at final follow-up. RESULTS: Seven knees in six @entity1 were evaluated with a mean follow-up of 34  10 (range 24 to 49months) months. There were only four clinical successes defined as an extensor lag less than 30  . Of the functioning knees at final follow-up (n=5) the overall extensor lag in this group did significantly improve from 50  13   to 20  15   (range 5 to 40  ) (p=.01). Mean postoperative flexion at final follow-up was 115  8  . Mean Knee Society Score for function improved from 20  30 to 45  54 (p=.03) as did the mean Knee Society Score for @entity158 (44  18 vs. 74  78, p=.02). DISCUSSION: @entity7502 mesh offered limited postoperative functional results when used as an augment to the multiply operated knee that sustains a complete @entity397 after TKA, but did allow for significant improvement in postoperative @entity158 outcomes. LEVEL OF EVIDENCE: IV.
