Ankle impingement syndrome is most often seen in athletes or sports enthusiasts. Repeated strong dorsiflexion of the foot causes the distal tibia and talus to impinged on each other, resulting in soft tissue scarring and bone growth due to long-term irritation. Some patients also develop symptoms because they have not received standardized treatment after ankle sprains and have ligamentous laxity, resulting in chronic ankle instability, which causes excessive joint wear and bone growth. The symptoms of ankle impingement syndrome are dominated by swelling and pain in the ankle joint, and the anterior osteophyte can affect the dorsiflexion activity of the ankle joint, resulting in limited dorsiflexion and pain. Treatment Early treatment can be conservative, including physical therapy, anti-inflammatory and pain medication, rest and reduced activity. If conservative treatment is not effective, arthroscopic debridement surgery may be considered. The goal of surgery is to remove bony or soft tissue obstructions that affect joint movement, release intra-articular interlocking, and remove pain-causing factors from the joint to relieve pain symptoms and improve ankle mobility. Prevention Adjust the exercise program to avoid overload. Wear appropriate protective gear during exercise to limit ankle overactivity. Perform lower limb muscle strength exercises to enhance ankle stability and balance and proprioceptive exercises to enhance ankle stability and sensitivity and reduce the incidence of ankle sprains. Once the ankle sprain occurs, actively standardize the treatment to avoid the legacy of ankle instability and other problems.
