Extensor mechanism complications involving the patella frequently result in total knee arthroplasty (TKA) failure. Postoperative patellar dislocation may be caused by soft tissue imbalance, improper sizing, and position of the prosthesis. This report describes a case of revision TKA requiring several rounds of soft tissue releases in an effort to treat the patient's chronic patellar dislocation. In the process, a novel surgical approach was developed for the surgical management of refractory chronic patellar dislocations...

Neglected patella non-unions are rare. Contraction of the quadriceps makes late repair extremely difficult. A case of distal patella pole fracture neglected for 8 years is presented. The patient was a hemiplegic young female unable to walk due to extensor mechanism deficiency with a 10 cm retraction of the patella proximal pole at her neurologically intact side. The quadriceps was lengthened using a spanning unilateral external fixation system and the fragments successfully united after trans-osseous suture repair...

INTRODUCTION: Modified tension band wiring has been widely used to treat transverse patellar fractures. However, few studies have evaluated the clinical outcomes using different methods of Kirschner wire bending, location of the tension band, and depths of Kirschner wires. Thus, we tried to clarify these factors according to our clinical outcomes. PATIENTS AND METHODS: This retrospective cohort study recruited consecutive patients underwent surgical fixation for patellar fractures using modified tension band technique between January 2010 and December 2015...

Osteochondral fracture of the patella is a common concomitant injury of the knee, especially in lateral patellar instability, and the importance of early stable fixation with minimal complication and early mobilization should be emphasized. Screws and Kirschner wires both absorbable and nonabsorbable have been the common mode of fixation of these fractures. Nevertheless, these fixation techniques require larger osteochondral fragments and are associated with cartilage abrasion, hardware prominence, synovitis, and foreign body reaction...

Recurrent patellar instability is a common pathology and typically affects younger and more active patients. To prevent complete lateral dislocation of the patella, several osseous and soft-tissue procedures have been previously described, including reconstruction of the medial patellofemoral ligament (MPFL), which has been identified as the primary medial stabilizer of the patella. Several techniques have been reported for reconstruction of the MPFL, sometimes in conjunction with other procedures, with the majority showing success in the treatment and resolution of patellar instability...

PURPOSE: Even if medial patellofemoral ligament (MPFL) reconstruction is a proven method, complications such as implant loosening, patella fractures, recurrent luxations, knee pain or knee stiffness are frequently described. Besides a correct tunnel positioning and implant-specific complications, this might be caused by difficulties with an appropriate graft tensioning. The study presented here is a necessary first step in exploring our technique of a double-limbed, hardware-free MPFL reconstruction, which provides another way to test and adjust the graft tension before permanent fastening...
