Summary
Unicondylar knee arthroplasty offers a good solution for early knee compartment degeneration. This minimally invasive surgery shows excellent mid-term results, improving function and reducing pain for patients.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Context:
- Minimally invasive techniques for unicondylar knee prostheses are gaining interest.
- Indications include single compartment arthrosis in patients over 50, under 80kg, with minor axis deviations and intact ligaments.
Purpose:
- To present mid-term postoperative results of the Repicci unicondylar knee prosthesis.
- To evaluate the effectiveness of unicondylar knee arthroplasty for medial compartment arthrosis.
Summary:
- 25 patients (26 knees) with varus deformity and medial compartment arthrosis (Ahlback type 1-4) underwent implantation.
- Average follow-up was 31.8 months, showing good axial correction (6.2 degrees), 118-degree flexion, and minimal extension lag.
- Knee Society scores improved significantly (knee: 60 to 86.8; functional: 30.9 to 71.1), with pain reduction (VAS: 6.8 to 2).
Impact:
- Unicondylar knee arthroplasty is a viable option for early degenerative knee changes.
- The procedure demonstrates advantages over other treatment options, suggesting increased future use.
