Background: Day-case anterior cruciate ligament reconstruction has the potential benefit of reduced hospital stay and reduced cost of care. The goal of this preliminary report was to compare the outcome of day-case arthroscopic anterior cruciate ligament reconstruction with those of in-patient care in terms of pain control and short-term functional outcome.
Materials and methods: This was a prospective comparative study involving patients who had anterior cruciate ligament reconstruction performed in our unit between January 2019 to July 2021 for isolated anterior cruciate ligament rupture. The patients were offered the option of in-patient and day-case anterior cruciate ligament reconstruction. All cases were isolated anterior cruciate ligament ruptures with no other ligament injury.
Results: A total of twenty-one-day case and twenty-five in-patient anterior cruciate ligament reconstruction were managed during the period of the study. The median numeric pain scores at day 2 and 7 in the day case group was 8.0 (IQR=2.0) and 5.0 (IQR= 3.0) respectively and in-patient group was 7.0 (IQR =1.5) and 4.0 (IQR= 2.0) respectively. The international knee documentation score (IKDC) at 6 months in the day case and in-patient groups were 68.6 (IQR= 9.3) and 67.2 (IQR= 25.0) respectively. The Mann-Whitney U test indicated that patients who had ACL reconstruction on in-patient care basis had statistically significant lower visual analogue scale pain scores on the second (z=-2.58, P = 0.01) and seventh (z=-3.41 P = 0.001) post-operative days compared to patients who had ACL reconstruction on day case basis. There was no statistically significant difference in the median IKDC scores of both groups at 6 months. The cost of care in the day case group was 40% lower than those of the in-patient group.
Conclusion: Although the cost of care in the day case group appeared lower as compared to the in-patient group, the day case group had higher post-operative pain scores compared to the in-patient group. Although the post-operative functional scores were similar in both groups, this was not statistically significant.
