Restoration of Constitutional Alignment in TKA with a Novel Osteotomy Technique.

J Knee Surg 2019 Jan 16. Epub 2019 Jan 16.

Department of Orthopedics, Army Medical University, Xinqiao Hospital, Chongqing, China.

Many studies have shown that restoration of the preoperative constitutional varus may lead to a normal knee status in total knee arthroplasty (TKA). It is also known that coronal femoral lateral bowing contributes to constitutional varus of the femoral shaft, and bilateral femoral lateral bowing (BFLB) can decelerate medial knee osteoarthritis progression. In this sense, the BFLB should be reserved in TKA. Read More

Management of Extra-articular Deformity in the Setting of Total Knee Arthroplasty.

J Am Acad Orthop Surg 2019 Jan 7. Epub 2019 Jan 7.

From the Adult Reconstruction and Joint Replacement Service (Dr. Sculco), the Department of Orthopaedic Surgery (Dr. Kahlenberg), and Limb Lengthening and Complex Reconstruction Service (Dr. Fragomen and Dr. Rozbruch), Hospital for Special Surgery, New York, NY.

Extra-articular deformities of the femur and tibia in conjunction with advanced knee osteoarthritis pose unique challenges for the arthroplasty surgeon. Careful preoperative planning is needed to evaluate both the intra- and extra-articular deformities and to determine the best route to total knee arthroplasty. An intra-articular compensatory correction can typically be performed if the extra-articular deformity is distant from the joint or if preoperative templating shows that bony cuts do not interfere with ligamentous attachments.

A mathematical model for predicting postoperative leg shortening after curved intertrochanteric varus osteotomy for osteonecrosis of the femoral head.

PLoS One 2018 18;13(12):e0208818. Epub 2018 Dec 18.

Department of Orthopedic Surgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University, Sapporo, Hokkaido, Japan.

Despite good clinical outcomes associated with curved intertrochanteric varus osteotomy for the treatment of osteonecrosis of the femoral head, post-operative leg-length discrepancy is frequently reported and might reduce patient satisfaction. Although previous report showed that varus angulation affected post-operative leg-length discrepancy, sufficient varus angulation is the most important factor for obtaining a lateral intact portion. Therefore, to ensure better postoperative outcomes, detection of other parameters associated with leg shortening may prove useful. Read More

Concomitant Arthroscopy With Labral Reconstruction and Periacetabular Osteotomy for Hip Dysplasia.

Arthrosc Tech 2018 Nov 15;7(11):e1141-e1147. Epub 2018 Oct 15.

American Hip Institute, Westmont, Illinois, U.S.A.

In the setting of true hip dysplasia, the high prevalence of intra-articular pathology may lead to recurrent symptoms and failure after periacetabular osteotomy (PAO). Femoral neck osteochondroplasty, microfracture, removal of loose bodies, and labral repair are examples of procedures that are performed with concomitant arthroscopy. When damage to the labrum is too severe to repair, reconstruction instead of extensive debridement before PAO can be more effective in restoring the labral seal to maintain joint lubrication and chondral protection.

Background: Biochemical MRI of hip cartilage such as delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) and T2 mapping is increasingly used to judge cartilage quality in the assessment of femoroacetabular impingement (FAI). The current evidence is sparse about which of these techniques yields a stronger correlation with histologic cartilage degeneration because of the difficulty in validating biochemical MRI techniques against histology in the clinical setting. Recently, an experimental ovine FAI model was established that induces chondrolabral damage and offers a validated platform to address these limitations. Read More

Factors Affecting Tibial Tuberosity-Trochlear Groove Distance in Recurrent Patellar Dislocation.

Clin Orthop Surg 2018 Dec 21;10(4):420-426. Epub 2018 Nov 21.

Center for Joint Disease, Chonnam National University Hwasun Hospital, Hwasun, Korea.

Background: The tibial tuberosity-trochlear groove (TT-TG) distance is used to determine the necessity of tibial tubercle osteotomy. We conducted this study to determine the extent to which each of the tibial tuberosity lateralization, trochlear groove medialization, and knee rotation angle affects the TT-TG distance in both normal and patella dislocated patients and thereby scrutinize the rationale for tuberosity transfer based on the TT-TG distance.

Methods: Retrospective analysis of rotational profile computed tomography was done for patella dislocated and control group patients. Read More

Pannach, D. W. Howie, Department of Orthopedics & Trauma, Royal Adelaide Hospital, Adelaide, South Australia.

Background: The Bernese periacetabular osteotomy (PAO) is a complex surgical procedure with a substantial learning curve. Although larger hospital and surgeon procedure volumes have recently been associated with a lower risk of complications, in geographically isolated regions, some complex operations such as PAO will inevitably be performed in low volume. A continuous structured program of distant mentoring may offer benefits when low numbers of PAOs are undertaken, but this has not been tested. Read More

Retrograde Stainless Steel Flexible Nails Have Superior Resistance to Bending in Distal Third Femoral Shaft Fractures.

J Pediatr Orthop 2018 Nov 16. Epub 2018 Nov 16.

Texas Scottish Rite Hospital for Children, Dallas, TX.

Background: It has been shown that retrograde titanium flexible intramedullary nails (Ti FIN) provide superior resistance to bending compared to antegrade Ti FIN in distal femur fractures. The purpose of this study was to compare resistance to torsional and bending forces of stainless steel (SS) FIN, with or without a locking screw, and Ti FIN in distal third femoral shaft fractures.

Ten- and 20-year Survivorship of the Hip After Periacetabular Osteotomy for Acetabular Dysplasia.

J Am Acad Orthop Surg 2018 Nov 14. Epub 2018 Nov 14.

From Saint John's Health Center, Hip and Pelvis Institute, Santa Monica, CA (Dr. Ziran, Dr. Foster, and Dr. Matta), Straub Medical Center, Bone and Joint Center, Honolulu, HI (Dr. Varcadipane), David Geffen School of Medicine at UCLA, Los Angeles, CA (Dr. Kadri and Dr. Ussef), and Cedars-Sinai Spine Research Center, Los Angeles, CA (Ms. Kanim).

Introduction: Acetabular dysplasia is a multifactorial condition characterized by a shallow hip socket with predisposition to osteoarthritis of the hip. The Bernese periacetabular osteotomy (PAO), developed by Reinhold Ganz in 1984, reorients the dysplastic hip joint to provide more uniform coverage of the femoral head and to extend the longevity of the native hip. Since 1987, the senior author performed the Bernese PAO on more than 430 patients. Read More

Effects of a Pasty Bone Cement Containing Brain-Derived Neurotrophic Factor-Functionalized Mesoporous Bioactive Glass Particles on Metaphyseal Healing in a New Murine Osteoporotic Fracture Model.

Int J Mol Sci 2018 Nov 9;19(11). Epub 2018 Nov 9.

Experimental Trauma Surgery, Justus-Liebig-University Giessen, Aulweg 128, 35392 Giessen, Germany.

The development of new and better implant materials adapted to osteoporotic bone is still urgently required. Therefore, osteoporotic muscarinic acetylcholine receptor M3 (M3 mAChR) knockout (KO) and corresponding wild type (WT) mice underwent osteotomy in the distal femoral metaphysis. Fracture gaps were filled with a pasty α-tricalcium phosphate (α-TCP)-based hydroxyapatite (HA)-forming bone cement containing mesoporous bioactive CaP-SiO₂ glass particles (cement/MBG composite) with or without Brain-Derived Neurotrophic Factor (BDNF) and healing analyzed after 35 days.
