Peking University Third Hospital120 enrolled

Overview

To compare the clinical outcomes of CAI patients with and without lateral ankle avulsion fracture after ligament repair/reconstruction, and to analyze the risk factors associated with the outcome.

80 patients with external ankle ligament injury without avulsion fracture and 40 patients with external ankle ligament injury combined with avulsion fracture were treated by surgery in our department. The outcomes included Karlsson score, VAS, AOFAS and Tegner score. The outcomes were compared between the two groups, and the risk factors were analyzed.

Outcomes

Primary Outcomes

Karlsson score

The Karlsson score consists of seven questions covering ankle pain, swelling, levels of daily activity and exercise .et al,provided by the patient with objective scores. The minimum and maximum values of Karlsson are 0 and 100, respectively. And higher scores mean a better outcome

Time frame: 2 weeks, 3 months, 6 months, 1 year, and 2 years

Secondary Outcomes

Visual Analogue Scale (VAS)

The Visual Analogue Scale (VAS) is designed to present to the respondent a rating scale with minimum constraints. Respondents mark the location on the 10-centimeter line corresponding to the amount of pain they experienced. This gives them the greatest freedom to choose their pain's exact intensity. It also gives the maximum opportunity for each respondent to express a personal response style. The minimum and maximum values of VAS are 10 and 0, respectively. And higher scores mean a worse outcome.

Time frame: 2 weeks, 3 months, 6 months, 1 year, and 2 years

American Orthopaedic Foot and Ankle Society (AOFAS)

The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score combines subjective scores of pain and function provided by the patient with objective scores based on the surgeon's physical examination of the patient (to assess sagittal motion, hindfoot motion, ankle-hindfoot stability and alignment of the ankle-hindfoot). The scale includes nine items that can be divided into three subscales (pain, function and alignment). The minimum and maximum values of AOFAS are 100 and 0, respectively. And higher scores mean a better outcome.

Time frame: 2 weeks, 3 months, 6 months, 1 year, and 2 years

Tegner Scale

The Tegner Scale is a tool commonly used to assess the degree of sports injury and the degree of functional recovery, which is graded according to the level of motor activity a participant participates in and the gradual increase in requirements. It is graded on a scale of 0 to 10, with the specific meanings.
