Summary
The modified Broström procedure effectively treats chronic lateral ankle instability, with arthroscopic evaluation identifying intra-articular issues. This approach yields excellent patient outcomes and stability.
Area of Science:
- Orthopaedic Surgery
- Sports Medicine
- Ankle Arthroscopy
Background:
- Chronic lateral ankle instability requires effective treatment options.
- Nonanatomic procedures may compromise joint function.
- Anatomic reconstruction, like the modified Broström procedure, offers stability with fewer drawbacks.
Purpose of the Study:
- To evaluate the efficacy of the Gould modification of the Broström procedure for chronic lateral ankle instability.
- To assess intra-articular pathology in patients undergoing this procedure.
- To determine long-term patient outcomes and stability.
Main Methods:
- Twenty-one patients underwent arthroscopic evaluation and the modified Broström procedure.
- Patients completed validated outcome scores (AOFAS, Weber, Hamilton).
- Postoperative stress radiographs were compared to preoperative films for 14 patients.
Main Results:
- Ninety-five percent of patients had intra-articular pathology.
- Excellent mean scores were achieved: Modified Weber (96), AOFAS (97), Hamilton (100%).
- Postoperative stress radiographs showed minimal side-to-side difference (<3 degrees).
Conclusions:
- Intra-articular pathology is common in lateral ankle instability.
- Arthroscopic treatment of intra-articular issues combined with the modified Broström procedure leads to excellent outcomes.
- The modified Broström procedure provides significant long-term stability for ankle instability.
