Surgery

In the intricate field of arthroscopic surgery, clear visualization of the operational field is the cornerstone of a successful procedure. A groundbreaking study recently published in the esteemed Journal of ISAKOS has shed light on an innovative technique that significantly improves intraoperative visualization during one of the most common orthopedic procedures: arthroscopic rotator cuff repair.

The study, conducted by a team led by Dr. Tsvetan T. Tsenkov of the Medical University – Sofia, Department of Orthopaedics and Traumatology, along with his peers Dochka D. Tzoneva and Nikolay N. Dimitrov, presents a case-control analysis of diluted epinephrine injections at the portal site and their impacts on surgical visibility and outcomes.

In a significant advancement for the orthopedic surgery realm, a study published on January 11, 2024, in the Journal of ISAKOS (DOI: 10.1016/j.jisako.2024.01.007) has revealed that epinephrine injections administered at portal sites can effectively enhance intraoperative visualization during arthroscopic rotator cuff repair procedures. This breakthrough has the potential to revolutionize the approach to one of the most frequently performed surgeries in orthopedics.

The research, which hails from the distinguished Medical University – Sofia, Bulgaria, aimed to assess whether portal-site injections of a 1:200,000 epinephrine solution could provide a clearer view of the surgical field, thereby facilitating a more precise and efficient repair process for partial-thickness supraspinatus tears—a common and debilitating shoulder injury.

A cohort of 221 patients with an average age of 58.4 years was methodically selected and subjected to consecutive numbering before being split into two groups—a control group and an intervention group. Each patient with an odd number received the epinephrine injections. Executed by one surgeon, this meticulous approach added an extra layer of consistency to the study’s results.

The outcome was a resounding success according to the Johnson’s visibility classification, with the intervention group achieving satisfactory visibility in an impressive 80% of cases compared to 62% in the control group. This not only denotes an astonishing 18% improvement but also traverses the threshold of statistical significance with a p-value of 0.003.

Determined to substantiate their findings, the researchers employed another measure: a surgeon-specific 5-point ordinal Likert scale (LS). Again, the intervention group demonstrated superior results, exhibiting a marked reduction in incidents of worsened visibility, thus bolstering the already compelling evidence of the efficacy of epinephrine injections in enhancing surgical visualization.

Surprisingly, despite the apprehensions that such an addition could prolong the duration of surgery, the researchers found no statistically significant increase in operative time. Patients in the control group underwent surgery for an average of 82.2 minutes, while those in the intervention group were subjected to an averagely shorter duration of 80.9 minutes. This negligible difference, with a p-value of 0.056, underscores that the integration of epinephrine injections does not adversely affect operative timelines.

Reassuringly, the study also confirmed the safety of the intervention, as no injection-associated complications were recorded among the participants. This revelation is critical as it ensures that the benefits of improved visibility are not offset by other unforeseen surgical risks.

Granted a Level 3 case-control study status, the article underscores the importance of consistent innovation in surgical practices, especially in enhancing the visualization of the operative field. Improved visualization not only aids the surgeon in performing a precise and effective repair but also potentially reduces the risks of complications associated with poor visibility, such as iatrogenic damage to surrounding tissues.

The study’s lead author, Dr. Tsvetan T. Tsenkov, is a renowned figure in orthopedic and sports medicine. The Department of Orthopaedics and Traumatology at the Medical University – Sofia is well-regarded for its advancements in medical research, and this study serves as a testament to its commitment to elevating patient care standards.

Complementing Dr. Tsenkov’s expertise, Dochka D. Tzoneva from the Department of Anesthesia and Intensive Care, and Nikolay N. Dimitrov from the Department of Orthopaedics and Traumatology, provided invaluable insights into the anesthesia implications and the broader orthopedic impact of these findings, respectively.

The article, copyrighted © 2024 by Elsevier Inc., is a beacon of innovation marking a transformative moment in arthroscopic surgery. By incorporating a simple, cost-effective, and safe method into routine rotator cuff repair surgeries, surgeons can now optimize their view of the operative field without extending the overall surgery time.

This study has set the stage for more extensive trials and potential adoption into standard practice, marking an exciting development for surgeons and patients alike. Arthroscopic rotator cuff repair is a widespread procedure, often required to restore function and relieve pain in patients with shoulder injuries.

Given the implications of this research, industry professionals and medical institutions are poised to consider the inclusion of diluted epinephrine injections into their surgical protocols. As the medical community continues to refine and adopt such visionary practices, patients worldwide stand to benefit from enhanced surgical outcomes with quicker recovery trajectories.
