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...

Periprosthetic fractures after total knee arthroplasty (TKA) can present reconstructive challenges. Not only is the procedure technically complex, but patients with these fractures may have multiple comorbidities, making them prone to postoperative complications. Early mobilization is particularly beneficial in patients with multiple comorbidities. Certain patient factors and fracture types may make revision TKA the ideal management option. Periprosthetic fractures around the knee implant occur most frequently in the distal femur, followed by the tibia and the patella...

Patients with displaced patellar fractures typically present with disruption to the extensor mechanism requiring acute surgical intervention. Chronic patellar fractures with disruption of the extensor mechanism are uncommon, and few surgical options are available. The authors present a patient who sustained a fracture to the inferior pole of the patella in Africa 5 years prior that was managed conservatively with bands and a brace. He decided to pursue surgical intervention because of difficulties with leg extension, weakness, and ambulation...

RATIONALE: The patellar fractures are common in adults, but rare in children. As a particular type of patellar fracture, however, sleeve fractures are almost always limited to children in the under 16's group. PATIENT CONCERNS: Herein, we report a rare case of a 19-year-old healthy adult female who presented sleeve fracture at the superior pole of the left patella. The clinical and radiological features are found including joint effusion, anterior tilt of the patella and a shell of bone lying proximally to the patella...

The suprapatellar approach for intramedullary tibial nailing has become widely accepted over the past decade. A round sleeve is passed beneath the patella to protect the surface of the patellofemoral joint (PFJ). However, the round sleeve cannot be easily stabilized in the PFJ because it does not conform to the shape of the patellar apex. Consequently, we produced a heart-shaped sleeve to simplify the insertion of the entry sleeve during the suprapatellar approach. Using the new sleeve, the following procedure is used: (1) make a longitudinal 4 cm skin incision proximal to the patella to reach the PFJ, (2) insert the guide pin manually to the ventral edge of the tibial plateau, (3) insert the cannulated trocar along the guide pin, (4) insert the heart-shaped sleeve along the cannulated trocar, (5) remove the cannulated trocar, (6) ream the entry point through the heart-shaped sleeve...

PURPOSE: The general surgical approach for patellar fractures has a significant weakness, in that the articular facet is invisible because the fixation is performed using radiation amplifiers after exposing the fracture site through vertical or transverse dissection on the anterior patella. We report excellent outcomes in the surgical treatment of patellar fractures, using a medial parapatellar approach. METHODS: This study evaluated 20 patients who underwent surgery between August 2008 and April 2014 to correct patellar fractures with comminution or with displacement of the articular facet of ≥2 mm and who had ≥1 year of follow-up...

PURPOSE: Operative fixation of displaced patella fractures is considered to be standard of care. However, patients with inferior pole patella fractures have limited options in terms of fixation. This video demonstrates the repair of an inferior pole patella fracture using nonabsorbable suture fixation. METHODS: Suture repair of patella fractures is a clinically acceptable technique, yielding similar functional results to patella fractures treated with K-wires or cannulated screws while reducing the rates of removal of hardware after fixation...

Operative management of patella fractures continues to be associated with poor outcomes and high reoperation rates. Traditionally, tension band fixation has been used for more simple fracture patterns; however, fixation remains a challenge particularly for comminuted fractures. More recently, various types of plate fixation have been used and reported in the literature. Earlier mobilization after plate osteosynthesis of patella fractures is possible because of a more robust construct, with the potential for decreased knee stiffness and improved functional outcomes...

Patellar fractures can occur as a result of direct or indirect injuries. Indirect injury is more common and occurs when the patella fails in tension when the force exerted by the extensor mechanism exceeds that of the bone. Common mechanism of indirect injury is rapid knee flexion with fully contracted quadriceps muscle. Treatment with a tension band construct is indicated for transverse patella fractures without significant comminution. This can be performed with 18-gauge wire and either 2 parallel, longitudinally oriented cannulated screws or 2 Kirschner wires...

Patella fracture fixation remains a significant challenge for orthopedic surgeons. Although tension band fixation allows for reliable osseous union, especially in simple fracture patterns, it still presents several problems. Plate fixation of patella fractures is a method that allows for more rigid stabilization and earlier mobilization. At the authors' level 1 trauma center, one fellowship-trained trauma surgeon has transitioned to using a novel anterior, low-profile mesh plate construct for all types of patella fractures...
