RotoWire's certified athletic trainer and injury analyst, Jeff Stotts, delves into some of the key injuries around the league in Week 12.
Frank Kaminsky, Hornets
The Suns frontcourt rotation has been an enigma so far this season as injuries and suspensions have inhibited any chance at consistency. A significant injury for Kaminsky will only extend the confusion as he is slated to miss an extended period of time with a stress fracture in his right knee.
The patella (kneecap) is a sesamoid bone, meaning it floats within a tendon. In the case of the kneecap, the involved tendon is the quadriceps muscle group. This unique situation allows the kneecap to increase the moment arm of the tendon, resulting in an increase in torque on the joint. Increasing the torque has a positive overall effect on the range of motion of the joint, increasing the extent the knee can bend and rotate. Conversely, if the kneecap becomes limited by injury, the range of motion of the joint is negatively impacted and often times the leg cannot be entirely straightened.
Furthermore, the pathway the kneecap takes ensures it's in constant contact with another bone. As a result, injuries to the patella, like bone contusions or fractures, often require a considerable amount of time to appropriately heal. This is clear when examining the usual missed time for previous cases of patella stress fractures in the NBA. These players, including Blake Griffin and Jon Wall, missed an average of 49 games.
