Summary
Kalix subtalar arthroereisis effectively treated stage II posterior tibial tendon dysfunction, significantly improving patient outcomes and reducing pain. This surgical technique offers a viable alternative to traditional bone procedures.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Reconstruction
Background:
- Stage II posterior tibial tendon dysfunction presents a significant clinical challenge.
- Current treatment options for this condition have limitations.
Purpose of the Study:
- To evaluate the preliminary outcomes of Kalix subtalar arthroereisis in the sinus tarsi for stage II posterior tibial tendon dysfunction.
- To assess the efficacy and safety of this novel surgical approach.
Main Methods:
- Twenty-one patients with stage II posterior tibial dysfunction underwent surgical treatment.
- Procedures included tendon repair and implantation of a Kalix endorthesis in the sinus tarsi.
- Clinical evaluation utilized the America Orthopaedic Foot and Ankle Society (AOFAS) hindfoot-ankle score.
Main Results:
- Significant improvement in AOFAS scores from 47.2 preoperatively to 81.6 postoperatively.
- Marked reduction in pain, with AOFAS pain subscale improving from 16.3 to 31.6.
- High patient satisfaction (17/19) and willingness to repeat the procedure.
Conclusions:
- Kalix subtalar arthroereisis is a promising alternative to bone surgery for stage II posterior tibial dysfunction.
- The procedure offers effective correction and pain relief.
- Further research may explore optimal endorthesis sizing to minimize complications.
