Summary
This study found that not using post-operative closed-suction drains in unicompartmental knee replacement (UKR) surgery leads to fewer complications and lower costs. Drain usage in UKR offered no significant benefits for patient recovery or outcomes.
Area of Science:
- Orthopedic Surgery
- Surgical Innovation
- Patient Outcomes
Background:
- Unicompartmental knee replacement (UKR) is a common procedure.
- The necessity of post-operative closed-suction drains in UKR remains debated.
- Optimizing post-operative care pathways is crucial for patient recovery and resource management.
Purpose of the Study:
- To evaluate the efficacy and impact of post-operative closed-suction drains in UKR.
- To compare outcomes between UKR patients with and without drains.
- To assess the influence of drain usage on pain, complications, and cost.
Main Methods:
- Prospective randomized trial involving 78 patients undergoing UKR.
- Patients were divided into two groups: Group A (no drain) and Group B (with drain).
- Groups were matched for age, sex, and pre-operative hemoglobin levels.
Main Results:
- Group A (no drain) showed lower day-one analgesic requirements.
- Smaller knee circumference and fewer local wound complications were observed in Group A.
- No significant differences in post-operative pain, range of motion, or hospital stay were found between groups.
Conclusions:
- Avoiding post-operative closed-suction drains in UKR does not negatively impact patient outcomes.
- Drain usage in UKR increases procedural costs without providing significant clinical advantages.
- The findings support the omission of drains in UKR to improve efficiency and reduce expenses.
