Introduction
Total knee arthroplasty (TKA) is one of the most successful orthopedic procedures. This study compares minimally invasive vs conventional approaches in elderly patients.
Materials and Methods
Prospective randomized controlled trial of 156 patients aged ≥65 years.
Results
MIS group showed reduced blood loss (280ml vs 420ml) and shorter hospital stay (3.2 vs 4.8 days). Key outcomes are summarised in the table below.
| Outcome | MIS Group | Conventional Group | p-value |
|---|---|---|---|
| Blood loss (ml) | 280 ± 45 | 420 ± 62 | <0.001 |
| Hospital stay (days) | 3.2 ± 0.8 | 4.8 ± 1.2 | <0.001 |
| KSS at 6 months | 88 ± 6 | 86 ± 7 | 0.12 |
| Complication rate (%) | 4.2 | 5.8 | 0.45 |
Conclusion
Minimally invasive TKA offers measurable advantages in early recovery for elderly patients.
