This study presents a new surgical technique to save knee joints in patients with poor leg circulation, avoiding above-knee amputation. The method successfully preserved the knee in most patients, enabling early use of prosthetic limbs.

Area of Science:

  • Vascular Surgery
  • Orthopedic Surgery
  • Limb Salvage Procedures

Background:

  • Dysvascular patients with compromised below-knee skin viability often face above-knee amputation.
  • Marginal skin perfusion below the knee presents a significant challenge in limb salvage.
  • A medial to lateral skin blood flow gradient is often observed in these patients.

Purpose of the Study:

  • To describe a novel surgical technique for knee joint salvage in dysvascular patients.
  • To evaluate the efficacy of a medially based flap for limb salvage in 'at risk' individuals.
  • To reduce the rate of above-knee amputation in patients with below-knee vascular compromise.

Main Methods:

  • A surgical technique utilizing a flap based on the more vascular medial skin is described.

  • Vascular assessment to identify the medial-to-lateral skin blood flow gradient is crucial.
  • The technique was applied to 'at risk' patients with marginal below-knee skin viability.

    • Main Results:

    • The knee joint was successfully salvaged in 27 out of 34 treated patients.
    • The technique demonstrated a high success rate in preserving the knee joint.
    • Early prosthetic fitting and mobilization were achieved in successfully treated patients.

    Conclusions:

    • A flap based on medial skin is an effective strategy for knee joint salvage in dysvascular patients.
    • This technique offers a viable alternative to above-knee amputation for select patients.
    • Successful limb salvage facilitates improved patient mobility and prosthetic rehabilitation.
