Summary
Arthroscopic ankle fusion is effective for osteoarthrosis without significant deformity. This minimally invasive procedure shows high union rates and excellent long-term outcomes for patients.
Area of Science:
- Orthopedic Surgery
- Arthroscopy
- Joint Fusion
Background:
- Osteoarthritis of the ankle often leads to pain and limited mobility.
- Surgical intervention, including ankle arthrodesis, is considered for severe cases.
- Minimally invasive techniques are sought to reduce morbidity.
Purpose of the Study:
- To evaluate the efficacy and outcomes of arthroscopically assisted ankle arthrodesis.
- To assess union rates and functional results in patients with minimal ankle deformity.
Main Methods:
- Nineteen patients with ankle osteoarthrosis and minimal deformity underwent arthroscopic fusion.
- Procedures involved arthroscopic debridement of articular surfaces and fixation with three cannulated screws.
- Radiographic and clinical outcomes were assessed postoperatively.
Main Results:
- Radiographic union was achieved in 18 out of 19 patients, with most achieving fusion by three months.
- One patient experienced non-union, requiring subsequent open arthrodesis.
- At two years, 12 patients had excellent, 4 good, and 2 fair results, with one poor outcome due to non-union.
Conclusions:
- Arthroscopically assisted ankle arthrodesis is a viable option for select patients with ankle osteoarthrosis.
- The procedure demonstrates favorable union rates and good to excellent long-term functional outcomes.
- Minimally invasive approach offers short postoperative morbidity.
