Summary

Osteotomy can effectively correct post-traumatic lower extremity deformities, offering significant pain relief, especially for extraarticular malunions. This procedure can also aid future total knee replacement in select arthritis cases.

Area of Science:

  • Orthopedic surgery
  • Trauma reconstruction
  • Limb deformity correction

Background:

  • Osteotomies for post-traumatic lower extremity deformities are complex and less understood than those for congenital conditions.
  • This study investigates the outcomes of osteotomy without total knee replacement for correcting fracture malunion deformities.

Purpose of the Study:

  • To evaluate the effectiveness of osteotomy in correcting post-traumatic lower extremity deformities and alleviating associated arthritic pain.
  • To compare outcomes between intraarticular and extraarticular malunions.

Main Methods:

  • A multicentric retrospective study of 28 patients (mean age 46.4) who underwent osteotomy for post-traumatic osteoarthritis (mean 17.3 years post-trauma).
  • Patients had intraarticular (6) or extraarticular (22) malunions, with 11 valgus and 17 varus deformities.

Clinical Effects of Ultrasound-Guided Acupotomy in Knee Osteoarthritis Treatment

Published on: April 26, 2024

  • Follow-up included clinical and radiographic assessment at a minimum of 2 years.

    • Main Results:

    • Significant improvement in pain scores was observed, particularly in extraarticular malunions (P=0.03).
    • Moderate functional improvement occurred, with no change in articular range of motion.
    • Osteotomy corrected deformities by an average of 9° (valgus) and 10° (varus).

    Conclusions:

    • Osteotomy is effective in correcting multi-component deformities at the distal femur and proximal tibia, improving mechanical axis and realignment.
    • Pain relief is more pronounced in extraarticular malunions; osteotomy can be broadly indicated for unicompartmental grade 2 and 3 arthritis in young patients.
    • Osteotomy can provide temporary relief and facilitate future total knee replacement surgery.
