Abstract:

Background

With the vigorous development of mass sports and fitness movement, sports injuries increase gradually. There is a significant increase in all kinds of ankle trauma morbidity. With the mature of ankle arthroscopy technology, minimally invasive arthroscopic treatment of ankle trauma has become the routine treatment methods.

Objective

To investigate the effect of arthroscopic debridement, micro-fracture fixation and anterior talofibular ligament reconstruction with autologous patellar tendon graft for treatment of chronic lateral ankle instability with exfoliative talus osteochondritis.

Methods

From July 2010 to December 2013, 21 cases of chronic lateral ankle instability with exfoliative talus osteochondritis were included. Routine preoperative lateral ankle, oblique radiography, MRI examination were used to confirm the diagnosis. The function of ankle and foot were evaluated with the AOFAS ankle-foot scoring system before and after surgery. Arthroscopic surgery was performed to clean the hypertrophy inflammatory synovial tissue planing and the damaged articular cartilage. If necessary, microfracture surgery was performed. The third patellar tendon with the tibia bone block was used for reconstruction of the anterior talofibular. The operated ankle was bandaged and drained for 1 to 2 days. Continuous ice compresses were used. Patients were discharged at postoperative 5-7 days. Patients were allowed to weight-bearing walk with ankle brace after 1 to 2 weeks.

Results

All patients did not suffer from severe perioperative complications. Patients were followed up for 6 to 24 months. No patients were suffering from ankle pain, infections and other complications. The AOFAS were significantly improved from 45.2 ± 10.1 points preoperative to 90.1 ± 6.1 postoperative (P <0.05). Subjective patient satisfaction was 90.5%.

Conclusion

Arthroscopic debridement, micro-fracture fixation and anterior talofibular ligament reconstruction with autologous patellar tendon graft was an efficacy treatment for chronic lateral ankle instability with exfoliative talus osteochondritis.
