Objectives: (1) To compare the postoperative outcomes in patient who underwent multifilament knee reconstruction (MLKR) with or without internal brace augmentation and (2) To examine potential differences in outcomes of patients with different access to postoperative rehabilitation following MLKR. Methods: Adult patients sustaining a multifilament knee injury (MLKI) from 2007 to 2020 who were surgically treated by a single surgeon were retrospectively identified and invited to participate. Patients with incomplete follow up data were excluded. Data recorded included patient demographics, intraoperative procedure performed (with versus without use of internal brace), patient access to rehabilitation after surgery (limited versus full access) and postoperative patient reported outcomes. The last included the Multiligament Quality of Life Questionnaire (MLQOL), PROMIS Computer Adaptive Testing (CAT) for Physical Function, Mobility, and Pain Interference, and the Lysholm Knee Questionnaire. Descriptive statistics were conducted using STATA. Comparison of the postoperative outcomes was performed between patients who received or did not receive internal brace during MLKR and those who had limited versus full access to postoperative rehabilitation, using descriptive statistics (STATA). The level of statistical significance was set at Results: A total of 85 (15 females,70 males) patients met the inclusion criteria. Of those, 62 patients (13 females, 49 males underwent MLKR without internal brace augmentation (NIB group) and 23 patients (2 females, 11 males) underwent MLKR with internal brace augmentation (IB group). Patient age and BMI were similar between the IB and NIB groups (Table 1). The mean follow-up time was 5.2+/-0.6 years on the NIB group and 1.5+/-0.1 years in the IB group (pConclusions: Internal bracing augmentation did not result in significant improvement of postoperative outcomes in patients undergoing MLKR, compared to the traditional technique without the use of internal brace, at short-term follow up. Postoperative rehabilitation is critical in patients who undergo MLKR, as patients with limited access to may experience worse outcomes at short term follow up in comparison to those who have full access to rehabilitation services. The socioeconomic status of the MLKR candidates should be examined preoperatively, and efforts should be made to grant these patients access to postoperative rehabilitation in order to optimize their clinical outcomes. |
