Summary
Mini-incisions in total hip arthroplasty (THA) reduced operative time and blood loss, particularly with posterior approaches. However, long-term outcomes and complications showed no significant difference compared to standard incisions, necessitating further high-quality research.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
Background:
- Total hip arthroplasty (THA) is a common procedure for hip joint issues.
- Surgical approach and incision size are critical factors influencing operative outcomes.
Purpose of the Study:
- To compare operative outcomes between mini-incisions and standard incisions in total hip arthroplasty.
- To evaluate the impact of surgical approach and trial quality on outcomes.
Main Methods:
- Systematic review and meta-analysis of 12 randomized or quasi-randomized controlled trials (RCTs/qRCTs) published between 1996 and 2008.
- Subgroup and sensitivity analyses were conducted based on surgical approach, trial quality, and follow-up duration.
Main Results:
- Mini-incisions significantly reduced operative time and blood loss, especially with posterior or posterolateral approaches.
- No significant differences in postoperative complications, Harris hip scores, or most radiographic results were observed between mini and standard incisions.
- Cup anteversion showed a difference between the groups.
Conclusions:
- Mini-incisions in THA demonstrate comparable short-term outcomes to standard incisions, with benefits in reduced operative time and blood loss for specific approaches.
- Further high-quality studies with longer follow-up are required to definitively assess the long-term efficacy and safety of mini-incisions in THA.
