What’s New in Orthopaedic Rehabilitation 2020

Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 13 subspecialties. Click here for a collection of all such OrthoBuzz specialty-update summaries.

This month, co-author Nitin B. Jain, MD selected the most clinically compelling findings from the >30 studies summarized in the November 18, 2020 “What’s New in Orthopaedic Rehabilitation.”

Hip Fracture
–A retrospective cohort study of >43,000 patients with hip fracture and dementia¹ found that more frequent, earlier, and larger amounts of postoperative, in-hospital rehabilitation were associated with better recovery in activities of daily living after discharge.

Rotator Cuff
–A cohort study used propensity-score techniques to compare surgical treatment with nonoperative treatment in 127 patients with symptomatic rotator cuff tears.² At the 18-month follow-up, patients who underwent operative treatment had significantly better shoulder pain and function outcomes than those who underwent nonoperative treatment.

Anterior Cruciate Ligament (ACL)
–A large prospective multicenter study investigating how rehabilitation factors affect the risk of revision ACL procedures after primary reconstruction yielded good news and bad news about the use of an ACL derotational brace for return to activity. Good: Those using the brace had much-improved KOOS scores at 2 years. Bad: Use of the brace doubled the odds of requiring another surgery within 2 years.

Total Knee Arthroplasty (TKA)
–A randomized controlled trial (RCT) of >300 patients who underwent TKA compared traditional in-home or at-clinic rehabilitation with virtual rehabilitation. The 3 main findings after 12 weeks were as follows:

• The virtual rehab group had a significantly lower median cost.
• Virtual rehab was not inferior based on KOOS assessments.
• There were fewer rehospitalizations in the virtual-rehab group.

Orthobiologics
–An RCT compared the efficacy of an ultrasound-guided injection of leukocyte-rich platelet-rich plasma (PRP), leukocyte-poor PRP, and a control saline injection to treat patellar tendinopathy.³ At the 1-year follow-up, neither PRP formulation was found to be more efficacious than the control injection.
