Patellar Tendon Avulsion from TKR



- Discussion:
    - avulsion of the patella tendon is a serious complication that is very difficult to treat;
    - when the knee is flexed intraoperatively, the tendon insertion may be stressed to the point of partial or complete avulsion;
    - this is particularly true in patients who have had a HTO or who are undergoing revision arthroplasty, becuase scar tissue makes patella
         eversion more difficlt and the patellar tendon may be shortened;
    - extensive soft tissue release from proximal tibia, V-Y quadricepsplasty, or elevation of patellar tendon w/ bony block can be used to 
         prevent tendon avulsion and improve the exposure of the knee;
    - patellar tendon rupture is best treated with primary repair, but knee arthrodesis ultimately may be required
