Dilemma of Supra- or Infrapatellar Tibial Nailing: Anterior Knee Pain vs. Intra-Articular Damage.

Int J Clin Pract 2022 21;2022:8220030. Epub 2022 Apr 21.

Orthopaedics and Traumatology Department, Sultan Abdulhamid Han Training and Research Hospital, Uskudar, Istanbul, Turkey.

Aim: Intramedullary nailing (IMN) is widely accepted as the treatment of choice for tibial fractures, and a suprapatellar method has been described to prevent common problems associated with the typical infrapatellar IMN technique, such as anterior knee pain. However, in the suprapatellar technique, injury to intra-articular structures is a concern. The aim of this study was to compare the clinical and radiological results of suprapatellar and infrapatellar IMN in terms of union, complications, and function. Read More

Outcomes for a custom-made anchor-like plate combined with cerclage in the treatment of inferior pole patellar fracture.

BMC Musculoskelet Disord 2022 May 14;23(1):452. Epub 2022 May 14.

Department of Orthopaedics and Trauma, Hong Hui Hospital, Xi'an Jiaotong, University College of Medicine, No. 555, East Youyi Road, Xi'an, 710000, Shaanxi, China.

Objective: An inferior pole fracture of the patella requires surgical treatment to restore the knee extension mechanism of the knee joint. Different from other types of patellar fractures, inferior pole fractures are usually comminuted, and other traditional fixation methods, such as tension band wiring, may not meet the fixation needs. We propose fixing inferior pole fractures of the patella with a custom-made anchor-like plate combined with cerclage and report the surgical outcomes. Read More

The Effect of Patellar Surface Morphology on Subchondral Bone Alignment When Matching Patellar Osteochondral Allografts to the Central Ridge of the Patella.

Am J Sports Med 2022 05 19;50(6):1635-1643. Epub 2022 Apr 19.

MedSport, Department of Orthopaedic Surgery, University of Michigan, Ann Arbor, Michigan, USA.

Background: Cartilage transplants in the patellofemoral joint have demonstrated lower success rates than in the femoral condyles. This is likely related to the more complex morphology and biomechanics of the joint. While previous studies have evaluated cartilage surface matching and congruence, little work has been done to study the associated subchondral bone congruency in these grafts. Read More

Chronic Osteochondral Fractures of the Patella Managed with Open Reduction and Internal Fixation Yields Excellent Knee Function.

J Knee Surg 2022 Apr 18. Epub 2022 Apr 18.

Department of Orthopaedics, All India Institute of Medical Sciences, New Delhi, India.

Currently, the management of acute osteochondral fractures (OCFs) of the patella is well established. However, the management of chronic OCFs remains debatable, as it is not clear whether such lesions can be accurately reduced or whether they will reliably heal. With well proven results of open reduction and internal fixation (ORIF) with headless compression screws (HCS) for acute OCFs, the application of this technique in late presenting cases is inconclusive.

An improvement on the technique of transosseous tunnels for the fixation of lower pole patella fracture: Cerclage around the patella.

Jialang Hu Xin Guo

Medicine (Baltimore) 2022 Mar;101(9):e28979

Department of Orthopedics, Wuhan Fourth Hospital, Puai Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

Abstract: The technique of transosseous tunnels is widely used in lower pole patella fracture (LPP). Though the extensor mechanism can be restored, distal avulsion fragments are usually unstable. The subsequent fracture gap and nonunion impair the extensor mechanism in turn. Read More

Excellent clinical and radiological outcomes after both open flake refixation and autologous chondrocyte implantation following acute patella dislocation and concomitant flake fractures.

Knee Surg Sports Traumatol Arthrosc 2022 Feb 26. Epub 2022 Feb 26.

Department of Orthopedic Sports Medicine, Technical University of Munich, Ismaninger Str. 22, 81675, Munich, Germany.

Purpose: To investigate clinical and magnetic resonance (MR) imaging results of patients undergoing patella stabilization with either open flake refixation (oFR) or autologous chondrocyte implantation (ACI) and concomitant soft tissue patella stabilization after sustaining primary, acute patella dislocation with confirmed chondral and/or osteochondral flake fractures. It was hypothesized that refixation will lead to better results than ACI at mid-term follow-up.

Methods: A retrospective chart review was conducted to identify all patients undergoing oFR or ACI after sustaining (osteo-)chondral flake fractures and concomitant soft tissue patella stabilization following primary, acute patella dislocation between 01/2012 and 09/2018 at the author's institution.

Consecutive ipsilateral inferior pole patella and superior patella sleeve fractures.

Ann R Coll Surg Engl 2022 Jun 17;104(6):e190-e192. Epub 2022 Feb 17.

Sheffield Teaching Hospitals NHS Foundation Trust, UK.

We present a rare, previously undescribed case of a superior patella sleeve fracture in a skeletally immature adolescent male, just 1 month following surgery for an ipsilateral traumatic inferior pole patella fracture. This was initially missed resulting in a delay to surgery. We recommend a high index of suspicion is key in these patients who re-present following subsequent trauma and alternative X-ray views such as a flexed lateral can be extremely beneficial. Read More

Editorial Commentary: Stabilize the Patella to Achieve Functional Gain but Don't Neglect the Cartilage That May Cause Long-Term Pain! Trochlear Dysplasia Plays a Role in Both.

John A Grant

Arthroscopy 2021 12;37(12):3477-3478

University of Michigan.

While trochlear dysplasia is commonly discussed as a major risk factor for recurrent patellar instability, it also has a strong relationship with the development of patellofemoral cartilage lesions. Patellofemoral instability frequently occurs in teens and young adults, and the high prevalence of associated cartilage damage unfortunately sets patients up for the progression of degenerative changes of the patellofemoral joint at an early age. The judicious use of magnetic resonance imaging can help identify the presence of chondral lesions, allowing for urgent management of associated osteochondral fractures or open discussions and patient education about the possibility of performing a cartilage restoration procedure concurrently with patellar stabilization surgery.

Osteochondral Fractures After Patellar Dislocation: Current Concepts.

J Am Acad Orthop Surg Glob Res Rev 2021 12 2;5(12). Epub 2021 Dec 2.

From the Royal National Orthopaedic Hospital, Brockley Hill, Stanmore, UK (Mr. Khan); Children's Hospital of Philadelphia (CHOP), Philadelphia, PA (Dr. Baghdadi and Dr. Ganley); Hospital of the University of Pennsylvania, Philadelphia, PA (Dr. Carey and Dr. Sheth); and Walsall Manor Hospital, Moat Road, Walsall, UK (Mr. Moores).

Osteochondral fractures of the knee occur frequently after acute patellar subluxation or dislocation. They can be challenging to manage because of the difficulty in diagnosing and treating these injuries in a timely fashion, in addition to choosing the optimum fixation method. This review presents the background, considerations for patient evaluation, and the best treatment options available for osteochondral fractures. Read More
