Majority of ankle ligaments heal naturally. However, some with recurrent injuries or non-healing ligaments will need a surgery to either repair or reconstruct the ligament. A vast majority of ankle ligament injuries are on the outer side (lateral) of the ankle. Inner side (medial) ligaments are more sturdy and injuries are less common.
Diagnosis
With good physical examination, the ATFL (anterior talo fibular ligament) and CFL (calcaneo fibular ligament) injury can be identified, however when the ankle is acutely swollen and painful, it may be difficult to examine.
Treatment
Chronic Partial tear of ATFL and/or CFL
Non-healing partial tears can be treated with PRP injection followed by plaster cast for 4 weeks. This has to be followed by foot stretches for 2 weeks post removal of the cast. This treatment can help heal majority of partial tears. In patients with no improvement with this treatment and in those with high grade 2 or grade 3 tears, surgery becomes necessary.
Ankle Ligament Prehabilitation
Ankle Prehab exercises can be started once the pain and swelling improve. These help in regaining the knee movements and keep the muscles in a good condition.
Ankle ligament Surgery
The torn ligament is either repaired or replaced by your own spare piece of tissue. The surgical technique is decided based on the nature of the tear and the expertise available to repair it.
Graft material can be obtained from cadaver source (another person). However own tissue is preferred and the healing and take up of the material is better. One of the hamstring muscles from the inner side of the thigh is used. The spare muscle tendon is harvested through small keyholes. Usually the graft is fixed using bio-composite or PEEK (high grade polymer) suture anchors.
Ankle Ligament Surgery Rehabilitation
Post-surgery you can expect to be either in a plaster cast or walking boot. Early mobilisation is recommended. Partial weight bearing up to 3 weeks is advised. You will start non weight bearing stretches by 3 weeks. For full mobility it may take up to 6 weeks. To get back to running and other high impact activities usually around 4 to 6 months of time period is necessary.
