To compare postoperative isometric quadriceps strength indices (QI%) and hamstring strength limb symmetry indices (HI%) between partial thickness quadriceps tendon (pQT), full thickness quadriceps tendon (fQT) and bone-patellar-tendon bone (BPTB) autograft ACLR.
Patients with primary ACLR with pQT, fQT or BPTB autograft with documentation of quantitative postoperative strength assessments between 2016-2021 were included. Isometric Biodex data, including quadriceps (QI%) and hamstring (HI%) strength indices (calculated as the percentage of involved to uninvolved limb strength) were collected between 5-8 months and between 9-15 months postoperatively.
In total, 124 and 51 patients had 5-8- and 9-15-month follow-up strength data, respectively. There were no significant differences in the number of concomitant meniscus repairs between the groups (pQT vs. fQT vs. BPTB). No significant differences were detected in median (min-max) QI% between pQT, fQT, and BPTB 5-8 months [87% (44%-130%), 84% (44%-110%), 82% (37%-110%) or 9-15 months [89% (50%-110%), 89% (67%-110%), and 90% (74%-140%)] postoperatively. Similarly, no differences were detected in median HI% between the groups 5-8 months or 9-15 months postoperatively.
The study was unable to detect differences in recovery of quadriceps strength between patients undergoing ACLR with pQT, fQT, and BPTB autografts at 5-8 months and 9-15-months postoperatively.
