Which type of activity is inappropriate during the inflammatory response phase of a medial collateral ligament sprain?

• A. Lower extremity plyometrics
• B. Submaximal isometric quadriceps strengthening
• C. Hip joint stretching
• D. Upper extremity ergometry

Answer: (A)

During the inflammatory response phase after a medial collateral ligament sprain, the priority is to protect the healing tissue and minimize additional stress. The ligament is damaged and its fibers are vulnerable, so high-load, rapid-loading activities can disrupt repair and prolong swelling. Plyometric exercises involve quick, forceful landings and large joint loads, which can aggravate the injured knee and are therefore inappropriate in this phase. Safe alternatives include submaximal isometric quadriceps work to maintain muscle activation without moving the joint, gentle hip stretching within a pain-free range to preserve flexibility, and upper-extremity ergometry to keep conditioning without stressing the knee. As inflammation resolves and tissue capacity improves, progression toward more dynamic loading, then eventually plyometrics, can be considered.
