Satisfactory patient-reported outcomes at 5 years following primary repair with suture tape augmentation for proximal anterior cruciate ligament tears.

PURPOSE: An enhanced understanding of anterior cruciate ligament (ACL) healing and advancements in arthroscopic instrumentation has resulted in a renewed interest in ACL repair. Augmentation of a ligament repair with suture tape reinforces the ligament and acts as a secondary stabilizer. This study assesses the 5-year patient-reported outcomes of primary repair with suture tape augmentation for proximal ACL tears. METHODS: Thirty-seven consecutive patients undergoing ACL repair with suture tape augmentation for an acute proximal rupture were prospectively followed up for a minimum of 5 years. Patients with midsubstance and distal ruptures, poor ACL tissue quality, retracted ACL remnants and multiligament injuries were excluded. Patient-reported outcome measures were collated using the Knee Injury and Osteoarthritis Outcomes Score (KOOS), Visual Analogue Pain Scale (VAS-pain), Veterans RAND 12-Item Health Survey (VR-12) and the Marx Activity Scale. Patients with a re-rupture were identified. RESULTS: Three patients were lost to follow-up leaving 34 patients in the final analysis (91.9%). The mean KOOS at 5 years was 88.5 (SD 13.8) which improved significantly from 48.7 (SD 18.3) preoperatively (p < 0.01). The VAS score improved from 2.3 (SD 1.7) to 1.0 (SD 1.5) and the VR-12 score improved from 35.9 (SD 10.3) to 52.4 (SD 5.9) at 5 years (p < 0.01). However, the Marx activity scale decreased from 12.4 (SD 3.4) pre-injury to 7.3 (SD 5.2) at 5 years (p = 0.02). Six patients had a re-rupture (17.6%) and have since undergone a conventional ACL reconstruction for their revision surgery with no issues since then. These patients were found to be younger and have higher initial Marx activity scores than the rest of the cohort (p < 0.05). CONCLUSION: Primary repair with suture tape augmentation for proximal ACL tears demonstrates satisfactory outcomes in 28 patients (82.4%) at 5-year follow-up. Six patients sustained a re-rupture and have no ongoing problems following treatment with a conventional ACL reconstruction. These patients were significantly younger and had higher initial Marx activity scores. LEVEL OF EVIDENCE: Level IV.

Combined Anterior Cruciate Ligament Repair and Anterolateral Ligament Internal Brace Augmentation: Minimum 2-Year Patient-Reported Outcome Measures.

BACKGROUND: The anterolateral ligament (ALL) contributes to anterolateral rotational stability of the knee. Internal bracing of the anterior cruciate ligament (ACL) and ALL reinforces the ligaments and encourages natural healing by protecting both during the healing phase and supporting early mobilization. PURPOSE/HYPOTHESIS: To assess the 2-year patient-reported outcomes of combined ACL repair and ALL internal brace augmentation. We hypothesized that significant improvements in outcomes would be seen. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 43 consecutive patients with acute proximal ACL ruptures were prospectively evaluated for a minimum of 2 years. The mean age at the time of surgery was 25.7 years (range, 13-56 years). Indications for the combined ACL/ALL procedure were associated Segond fractures, grade 3 pivot shift, or high levels of sporting activity. Patients with chronic ruptures or with multiligament injuries were excluded. The Knee injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) for pain, Veterans RAND 12-Item Health Survey (VR-12), and Marx activity scale were collected preoperatively and at 12 and 24 months postoperatively. Patients with any postoperative complications were identified at the time of this analysis. RESULTS: The mean follow-up period was 44.8 months. Five patients were lost to follow-up, leaving 38 patients (88.4%) in the final analysis. The mean KOOS for Pain, Symptoms, Activities of Daily Living, Sport/Recreation, and Quality of Life improved from a respective 64.9, 58.6, 75.0, 33.7, and 28.9 preoperatively to 91.1, 81.8, 96.1, 82.8, and 74.3 at the 2-year follow-up (P < .0001). The mean WOMAC scores for pain, stiffness, and function improved from 77.5, 65.3, and 75.0 preoperatively to 94.6, 88.6, and 96.0 at the 2-year follow-up (P < .0001). The VAS pain score improved from 3.4 preoperatively to 0.7 at the 2-year follow-up, and the VR-12 physical score improved from 34.4 preoperatively to 52.7 at the 2-year follow-up (P < .0001 for both ). However, the Marx activity score decreased from 13.3 preinjury to 10.6 at the 2-year follow-up (P = .01). Two patients (5.3%) sustained a rerupture. CONCLUSION: Combined ACL repair and ALL internal brace augmentation demonstrated excellent outcomes in 94.7% of the study patients. Based on our experience with this cohort as well as our isolated ACL repair data, we suggest that high-risk patients with ACL ruptures have an additional ALL procedure to provide rotational stability.

Vancomycin-soaked wrapping of harvested hamstring tendons during anterior cruciate ligament reconstruction. A review of the 'vancomycin wrap'.

The practice of 'vancomycin wrapping' of harvested hamstring autografts during Anterior Cruciate Ligament Reconstruction (ACLR) surgery has gathered recent interest. This practice involves the wrapping of harvested grafts in a vancomycin-soaked swab during the preparatory phase. Different techniques are observed, and a small number of studies have shown that pre-soaking hamstring ACLR grafts in this manner dramatically reduces the post-surgical infection rate compared with standard intravenous antibiotic prophylaxis alone. However, the literature surrounding this practice is surprisingly limited and thus the basis and rationale of the 'vancomycin wrap' has established itself largely without question. The exact popularity of this practice is difficult to establish but there has been increasing disclosure of its efficacy in reducing post-operative infection in ACLR since 2012. We provide a synopsis of the current literature surrounding vancomycin and its use in 'wraps' in ACLR to help apprise the surgeon of the nature of infection in ACLR, the rationale for vancomycin, whilst considering evidence to support alternatives and discussing potential ramifications for future practice.
