Conditions

Intra-articular Knee Fractures

Brief summary

Decreased range of motion is common after fractures around the knee and can impact a patient's ability to perform activities of daily living such as rising from a seated position or getting in and out of a bathtub. A continuous passive motion (CPM) machine is a machine that continuously moves a joint (such as the knee) without the patient having to use the muscles in his/her leg. A goal of this therapy is to maintain as much motion as possible following this injury. This study is a randomized, prospective study to evaluate the effectiveness of CPM in maintaining knee range of motion following open reduction and internal fixation (ORIF) of fractures around the knee

Healthy volunteers

Inclusion criteria

* If the patient has an intra-articular distal femur or proximal tibia fracture * Independent ambulatory prior to injury * No previous knee injury limiting motion

Exclusion criteria

* If the patients range of motion was decreased prior to injury (ex. Osteoarthritis, previous knee fracture or injury) * Any contraindication to CPM (concomitant hip or ankle fracture) * Open physis of tibia or distal femur * Pathological Fracture * Compartment Syndrome * Neurovascular injury * Fracture due to gunshot wound * Greater than 21 days from fracture to definitive open reduction and internal fixation * Fractures treated with definitive external fixation * Open fractures * Extensor mechanism injuries * Likely problems in the judgment of the investigator with maintaining follow-up
