Summary

Arthroscopic surgery offers a viable option for painful, stiff knee joints after total knee arthroplasty (TKA). This minimally invasive approach improved range of motion in most patients, providing a potential alternative to more invasive procedures.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Painful, stiff knee joints post-total knee arthroplasty (TKA) present a clinical challenge.
  • Previous conservative treatments at the institution yielded unsatisfactory outcomes.

Purpose of the Study:

  • To evaluate the efficacy of arthroscopic surgery for managing painful, stiff knee joints following TKA.
  • To assess the impact of arthroscopy on knee range of motion and patient outcomes.

Main Methods:

  • Arthroscopic surgery was performed on 11 patients with painful, stiff knees post-TKA.
  • Knee range of motion, particularly flexion, was measured pre- and post-operatively.

Main Results:

  • Eight out of eleven patients experienced good results following arthroscopic intervention.

  • An average improvement of 56.3 degrees in knee range of motion was observed.
  • Early postoperative flexion improved to 90 degrees in all patients, though benefits showed some decline over time.

    • Conclusions:

    • Arthroscopic surgery is a potential treatment option for painful, stiff knee joints after TKA.
    • It offers an alternative to manipulation or open arthrotomy, potentially avoiding associated complications.
    • While effective in the short term, long-term benefit maintenance requires further investigation.
