Postoperative Infection After Anterior Cruciate Ligament Reconstruction.

ABSTRACT:

Context

Infection after anterior cruciate ligament reconstruction (ACLR) is uncommon; if it occurs, it can lead to disastrous complications.

Objective

To analyze post-ACLR infections and identify related complications to provide the most effective treatment protocol.

Study design

Clinical review.

Level of evidence

Level 4.

Results

Among approximately 1850 ACLRs performed by a single surgeon over the past 20 years, 7 cases of post-ACLR infection were identified (incidence, 0.37%). Five patients presenting with low-severity infection were successfully treated without any complication or residual functional disability. The remaining 2 patients, although successfully treated, presented with minor residual limitations. From a literature review, 16 studies including 246 cases of infection were reported among 35,795 ACLRs, making the rate of infection 0.68% (range, 0.14%-2.6%).

Conclusion

With proper treatment protocols, post-ACLR infection is rare but can compromise outcomes.

Project description:PurposeTo compare postoperative pain scores and opioid use between patients undergoing a standard arthroscopic anterior cruciate ligament reconstruction (ACLR) using hamstring autograft with those undergoing a suture repair augmented with an extracellular matrix scaffold (bridge-enhanced ACL repair) performed through an arthrotomy and to determine factors predictive of postoperative opioid use and levels of overprescription.MethodsA nonrandomized controlled trial was conducted with 20 patients (10 ACLR, 10 bridge-enhanced ACL repair), aged 18 to 35 years. All surgeries were performed by a single surgeon. A pain medication log was provided to patients on discharge. No regional anesthesia was performed. Pain scores via a visual analog pain scale were recorded at each visit. Correlations between preoperative and intraoperative characteristics and postoperative opioid use were determined.ResultsThe total morphine-equivalent dose ranged from 30 to 309 mg (4-42 pills oxycodone) for the ACLR group and 75 to 254 mg (10-34 pills oxycodone) for the bridge-enhanced ACL repair group. The average opioid use per day was 35.8 mg for the patients undergoing bridge-enhanced ACL repair and 44.2 mg for patients undergoing ACLR (P = .29). Pain scores at time points up to 2 years postoperatively were not significantly different between the 2 groups. Across both groups, the average oversupply of oxycodone was 46 pills per patient, a greater than 70% unused opiate rate. Preoperative body mass index and preoperative Knee Injury and Osteoarthritis Outcome Scores pain score were predictive of greater postoperative opioid use per day, whereas age, concurrent meniscal repair, and operative time were not.ConclusionsTotal overall opiate intake was not different between the patients undergoing bridge-enhanced ACL repair through an arthrotomy and those undergoing arthroscopic ACLR. Both groups had similar pain scores from 2 weeks to 2 years postoperatively. Greater body mass index and greater preoperative pain (lower Knee Injury and Osteoarthritis Outcome Scores pain score) correlated with greater postoperative opioid use per day. There was an overprescription of opioids across all patients.Level of evidenceLevel III, case control study (therapeutic).
