Summary
Total knee arthroplasty (TKA) in post-traumatic osteoarthritis patients yields poorer functional outcomes and higher complication rates compared to degenerative osteoarthritis. This highlights the need for tailored treatment strategies for post-traumatic knee conditions.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Post-traumatic osteoarthritis (PTOA) presents unique challenges for total knee arthroplasty (TKA).
- Comparing TKA outcomes in PTOA versus degenerative osteoarthritis (DOA) is crucial for optimizing patient care.
Purpose of the Study:
- To analyze and compare the clinical and radiological outcomes of TKA in patients with PTOA versus DOA.
- To evaluate complication rates and revision surgery requirements in both patient groups.
Main Methods:
- A cohort of 43 patients with PTOA underwent TKA and were evaluated clinically and radiologically.
- Outcomes were assessed using Oxford Knee Score (OKS), Knee Society Scores (KSS), and Visual Analogue Scale (VAS).
- A matched-pair selection of DOA patients undergoing TKA served as the control group for comparison.
Main Results:
- TKA in PTOA patients resulted in significantly lower OKS and KSS scores compared to DOA patients.
- PTOA patients experienced higher complication rates (44.7%) and revision surgery rates (0.7 operations/knee) than DOA patients (21.1%, 0.3 operations/knee).
- Preoperative valgus malalignment greater than 10° in PTOA patients was associated with an increased revision rate (1.4 operations/knee).
Conclusions:
- TKA for PTOA leads to inferior functional outcomes and a higher incidence of complications and revisions compared to TKA for DOA.
- The heterogeneous nature of PTOA and associated anatomical abnormalities necessitate individualized treatment approaches.
- Surgical strategies for TKA in PTOA should be carefully tailored to patient-specific requirements and pathoanatomy.
