UNDERSTANDING STEPH CURRY’S GRADE 1 MCL SPRAIN
The 2016 NBA postseason took a dramatic turn Sunday evening when Warriors guard Stephen Curry suffered a right knee injury as the first half came to a close. He attempted to return to the start the third quarter but quickly retreated to the locker room before being ruled out for the game with a sprained knee.
The reigning MVP and heartbeat of a record-breaking Warriors team underwent a MRI on the injured joint Monday where it was determined he suffered a Grade 1 MCL sprain.
The injury occurred after Curry appeared to slip on a wet spot left by Houston big man Donatas Motiejunas, who also slipped just seconds before Curry hit the ground. Curry’s left leg extended backward while his right knee bent forward. His right foot appeared to remain planted on the court and the resulting valgus force of the fall overloaded the inside aspect of his knee, the location of the medial collateral ligament (MCL).
The MCL, along with the ACL, PCL, and LCL, serves as a primary stabilizer of the knee. Given its location, the MCL is critical in lateral or side-to-side movement. Damage to the medial meniscus often accompanies a MCL sprain as fibers of the ligament adhere to the fibrocartilage disc. Fortunately Curry appears to have avoided any meniscus involvement.
When a ligament like the MCL is sprained, the injury is often assigned a grade based on the amount of associated damage.
A minor or Grade 1 sprain is given when partial or micro tearing of the effected ligaments has occurred. A more moderate Grade 2 sprain is more commonly referred to as a partial tear and is more painful and limiting. Grade 2 injuries are often accompanied by a considerable amount of swelling and require rest and more intensive treatment. A Grade 3 sprain is relatively uncommon in sports but is a devastating injury. Grade 3 injuries result in a loss of function and mechanical stability and often require a long period of inactivity and in some cases surgery.
Fortunately for the Warriors, Curry’s mild MCL sprain can heal without surgical intervention. Instead conservative treatment and modalities will be used to address the associated symptoms and help stimulate the body’s natural healing process. The amount of time needed varies from person to person though the team has already determined he will sit for at least two weeks. When he does return expect Curry to wear a protective brace to help stabilize the area. Lateral movements, particularly on the defensive end, will be his biggest obstacle moving forward.
