What Is the First Treatment for Patellar Tendon Rupture?

The patellar tendon helps connect the kneecap to the shin and allows the quadriceps to straighten the knee. A complete tear can interrupt this mechanism, causing sudden pain, swelling, a change in the kneecap’s position, and difficulty lifting the straight leg.

Until the injury is assessed, the knee is commonly kept supported and movement is limited. Examination and imaging help determine whether the tear is complete, where it is located, and whether other structures were injured.

Do not test the knee repeatedly or attempt forceful stretching. Keep weight off the leg unless a clinician has specifically allowed it, and use support during transfers. Arrange urgent orthopaedic review, because delay can make restoration of the tendon’s normal length and function more difficult.

If repair is advised, Post-Operative Rehabilitation is gradual. Early protection is followed by carefully increased knee motion, quadriceps activation, walking control, and strengthening. The exact pace depends on the repair and the surgeon’s instructions.

Seek emergency assessment after a sudden knee injury if you cannot raise the straight leg, cannot bear weight, or notice major swelling or deformity. Numbness, a cold foot, or rapidly increasing pain also requires immediate attention.
