No Growth Disturbance After Trochleoplasty for Recurrent Patellar Dislocation in Adolescents With Open Growth Plates.

Am J Sports Med 2018 Nov 10;46(13):3209-3216. Epub 2018 Sep 10.

Orthopaedic Specialty Clinic, MVZ Oberstdorf, Teaching Hospital of the University of Ulm, Oberstdorf, Germany.

Background:: Trochlear dysplasia is the most important risk factor for patellofemoral instability among adolescents; therefore, trochleoplasty to reshape the trochlear groove is the treatment of choice for patients with high-grade trochlear dysplasia. However, in the presence of open growth plates, there is a potential risk of injury to the distal femoral growth plate and subsequent growth disturbance. As such, most authors do not recommend trochleoplasty for skeletally immature patients. Read More

Lateral Patellar Instability in the Skeletally Mature Patient: Evaluation and Surgical Management.

J Am Acad Orthop Surg 2018 Jun;26(12):429-439

From the Department of Orthopaedic Surgery, University of Virginia Health System, Charlottesville, VA (Dr. Diduch), StoneSprings Orthopedics, Dulles, VA (Dr. Kandil), and Orthopaedic Associates of Central Texas, Austin, TX (Dr. Burrus).

Lateral patellar instability is a common disease process that affects all types of patients. Depending on the patient's anatomy and the results of preoperative imaging, surgical management options include medial patellofemoral ligament reconstruction, tibial tubercle osteotomy, and sulcus-deepening trochleoplasty. Medial patellofemoral ligament reconstruction or repair is useful for almost all patients, whereas tibial tubercle osteotomy is helpful to correct a lateralized tibial tubercle and the associated elevated lateral pull of the extensor mechanism.

Heritability of patellar luxation in the Chihuahua and Bichon Frise breeds of dogs and effectiveness of a Swedish screening programme.

Vet J 2018 04 2;234:136-141. Epub 2018 Feb 2.

Swedish Kennel Club, S-16385 Spånga, Sweden.

Patellar luxation is one of the more common orthopaedic diseases of dogs and is relatively frequent in some toy breeds, including the Chihuahua and Bichon Frise. Using data provided by the Swedish Kennel Club, genetic parameters, including heritability, were estimated for patellar luxation in the Chihuahua from 1999 to 2014 and in the Bichon Frise from 1997 to 2014. The effects of the current screening programmes for patellar luxation in these breeds were evaluated. Read More

Quadriceps Tendon Autograft Medial Patellofemoral Ligament Reconstruction.

Curr Rev Musculoskelet Med 2018 Jun;11(2):209-220

Gelenkpunkt - Sports and Joint Surgery, Olympiastr 39, 6020, Innsbruck, Austria.

Purpose: Critically evaluate the published literature related to quadriceps tendon (QT) medial patellofemoral ligament (MPFL) reconstruction.

Recent Findings: Hamstring tendon (HT) MPFL reconstruction techniques have been shown to successfully restore patella stability, but complications including patella fracture are reported. Quadriceps tendon (QT) reconstruction techniques with an intact graft pedicle on the patella side have the advantage that patella bone tunnel drilling and fixation are no longer needed, reducing risk of patella fracture.

Special Considerations for Pediatric Patellar Instability.

Am J Orthop (Belle Mead NJ) 2018 Mar;47(3)

Division of Orthopaedic Surgery, Cincinnati Children's Hospital Medical Center, Cincinnati, OH.

Patellar instability in children and adolescents is a challenging subset to treat. Varied forms of instability, ranging from episodic dislocation to fixed dislocation, have been recognized. It is of utmost importance for the treating physician to recognize these different patterns of instability and their associated risk factors, as more complex patterns of instability would require more extensive surgical procedures.
