    • Nonoperative
      • immobilization in full extension
        • indications
          • partial tears with intact extensor mechanism
        • modalities
          • immobilization
            • hinged knee brace locked in extension for 6 weeks with weight bearing
          • rehabilitation
            • progressive active flexion / passive extension protocol
    • Operative
      • primary repair
        • indications
          • complete patellar tendon ruptures
          • ability to approximate tendon at site of disruption
        • techniques
          • end-to-end repair
          • transosseous tendon repair
          • suture anchor tendon repair
        • rehabilitation
          • locked extension brace with immediate weight bearing for 6 weeks
          • early motion protocol at 7-10 days with focus on passive extension and active flexion
        • outcomes
          • biomechanical studies have shown less gap formation with suture anchor repair compared to transosseous repair
          • clinical studies have shown a significant decrease in re-rupture rate with use of suture anchor compared to transosseous repair.
      • tendon reconstruction
        • indications
          • severely disrupted or degenerative patella tendon
          • chronic tears > 6-8 weeks out from injury
        • techniques
          • ipsilateral semitendinosus or gracilis autograft
          • central quadriceps tendon-patellar bone autograft
          • contralateral bone-patellar tendon-bone autograft or allograft
