This study on knee replacement surgery found that most patients experienced pain relief and good function after unconstrained knee arthroplasty, even with prior patellectomy and cruciate ligament removal.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Previous patellectomy can complicate knee arthroplasty.
  • Excision of cruciate ligaments in knee arthroplasty presents challenges.

Purpose of the Study:

  • To evaluate outcomes of unconstrained knee arthroplasty after patellectomy with cruciate ligament excision.
  • To discuss reasons for pain and instability in similar prior cases.

Main Methods:

  • Case series reporting on seven patients.
  • Unconstrained total knee arthroplasty with excision of both cruciate ligaments.
  • Previous patellectomy in all cases.

Main Results:

  • Six out of seven patients were completely pain-free.
  • Satisfactory function was reported in all seven cases.

  • Analysis of pain and instability factors.

    • Conclusions:

    • Unconstrained knee arthroplasty with cruciate ligament excision is a viable option after patellectomy.
    • This procedure can lead to pain relief and functional improvement.
    • Understanding complications is key for successful outcomes.
