HSS presents studies at 2017 AAOS Annual Meeting

New York, NY

At this year’s American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting, Hospital for Special Surgery (HSS) presented several studies related to innovations and leading research in orthopedics:

Hospital for Special Surgery Presents Data Validating Shorter, More Patient Friendly Outcomes Assessment for Revision Knee Replacement

• Researchers from HSS including Alexander McLawhorn, MD, MBA; Steven Haas, MD; Stephen Lyman, PhD and Michael Cross, MD, find that a shortened 7-question patient survey (KOOS JR.) is a valid tool to assess patient outcomes following revision total knee replacement.

Study Identifies Modifiable Risk Factors for Elbow Injuries in Baseball Pitchers

• Joshua Dines, MD, and David Altchek, MD, published a study that found that arm slot, arm speed and shoulder rotation have a significant relationship with elbow varus torque in professional baseball pitchers. Read the full press release here.

SSRI Antidepressants Associated with Increased Blood Loss and Transfusion Rates in Spinal Surgery

• Alexander Hughes, MD, investigated the impact of antidepressants on transfusion requirements in spinal surgery. Read the write-up here.

Study Shows Most Athletic Patients Return to Sports, Highly Satisfied with ACL Reconstruction Surgery

• Answorth Allen, MD, published a study that found that most patients who have ACL reconstruction surgery are highly satisfied, able to return to play and would have the procedure again. Read the full press release here.

Do New York Patients Need a Second Surgery Years after Minimally Invasive Hip Surgery?

• Stephen Lyman, PhD, published a population-based study that found that while hip arthroscopy in New York greatly increased in the past decade, revision hip surgery rates also continued to rise. Read the write-up here.

How Does Bariatric Surgery Impact Joint Replacement Outcomes in the Morbidly Obese?

• Alexander McLawhorn, MD, MBA, published a study that found that bariatric surgery performed prior to a total hip or knee replacement can reduce in-hospital and 90-day postoperative complications and improve patient health but does not reduce the risk of needing a revision surgery.

Study Finds Little Consistency in Doctor Reviews on Three Physician Ratings Websites

• Anil Ranawat, MD, investigated physician ratings website and found that reviews for individual sports medicine doctors were inconsistent across three popular websites. Read the full press release here.

Neurologic Complications Resolve in the Majority of Adult Spinal Deformity Surgeries

• Han Jo Kim, MD, presented a study that found that neurologic complications following spinal surgery resolve in the majority of patients and don’t impair quality of life. Read the write-up here.

Location of Spinal Correction Influences Risk of PJK Development

• Frank Schwab, MD, presented a study that reports for the first time that PJK (proximal junctional kyphosis) risk following lumbar spinal fusion depends on the level of the spine fused – fusing the lower portion of lumbar spine resulted in a decreased risk of PJK. Read the write-up here.

Most Young Shoulder Replacement Patients Can Resume Playing Sports

• Lawrence Gulotta, MD, presented a study that indicated that young active people who undergo shoulder replacement surgery can resume playing sports. Read the write-up here.

Study Cautions Against Use of Bone Morphogenetic Proteins (BMP) in Children’s Spine Surgery

• Emily Dodwell, MD, published a study finding that utilizing BMPs (bone morphogenetic proteins) did not improve revision rates for pediatric spinal fusions. Read the full press release here.

Study Finds Ligament Reconstruction is an Effective Treatment for Kneecap Instability in Patients with Trochlear Dysplasia

• Beth Shubin Stein, MD, presented her patient study that found that MPFL (medial patellofemoral ligament) reconstructions are a safe and effective treatment for patients with patellofemoral instability, even if they have trochlear dysplasia. Read the full press release here.

Study: Arthroscopic Hip Surgery Benefits Adolescents with Hip Impingement

• Anil Ranawat, MD, published research that found that the majority of adolescents undergoing arthroscopic hip surgery for adolescent femoroacetabular impingement saw positive outcomes. Read the write-up here.

Study: More than Half of College Football Athletes Have Inadequate Levels of Vitamin D - Deficiency Linked to Muscle Injuries

• Scott Rodeo, MD, presented research that found that more than half of college football athletes had insufficient Vitamin D levels which could leave them susceptible to muscle injuries. Read the full press release here.

Researchers Use Novel Technique to Stimulate Stem Cells in Damaged Tendon to Enhance Healing

• Scott Rodeo, MD, presented basic science study findings that tendon-derived endothelial cells produced chemical factors that stimulated intrinsic stem cells in the injured tendon thus increasing the strength of the tendon repair. Read the write-up here.
