Rotationplasty effectively treats osteosarcoma near the knee, enabling patients to walk without crutches and supporting body weight. This reconstructive surgery offers excellent functional outcomes with no local recurrence or metastasis observed.

Area of Science:

  • Orthopedic Surgery
  • Pediatric Oncology
  • Surgical Oncology

Background:

  • Osteosarcoma frequently affects the knee joint, necessitating limb-sparing surgical options.
  • Traditional treatments can lead to significant functional deficits.
  • Rotationplasty offers a reconstructive alternative for limb salvage.

Purpose of the Study:

  • To evaluate the functional outcomes and oncological safety of rotationplasty for knee joint osteosarcoma.
  • To assess patient quality of life and psychological adaptation post-surgery.

Main Methods:

  • Retrospective analysis of patients undergoing rotationplasty for osteosarcoma.
  • Assessment of local recurrence, metastasis, and functional range of motion.
  • Functional evaluation using the re-modified Enneking system.

Main Results:

  • No local recurrence or metastasis observed after an average 13.3-month follow-up.
  • Ankle joints (new knee joints) supported body weight with an average 75-degree range of motion.
  • All patients achieved independent ambulation without assistive devices or instability.
  • Average functional evaluation score was 84.5% (range 80.0-86.7%).
  • No psychological issues reported regarding limb adaptation.

Conclusions:

  • Rotationplasty is a viable and effective reconstructive technique for osteosarcoma around the knee.
  • The procedure yields excellent functional results and oncological control.
  • Patients demonstrate good physical function and psychological acceptance of the rotated limb.
