At issue is determining the best approach to rehabilitation after total knee arthroplasty, which is one of the most common surgical procedures in the United States, with an estimated prevalence in 2010 of 3.0 million women and 1.7 million men (J Bone Joint Surg Am. 2015 Sep 2;97[17]:1386-97).

For the new study, conducted at two Australian hospitals during 2012-2015, researchers recruited patients aged 40 years or older with a primary diagnosis of osteoarthritis who were undergoing a primary unilateral knee arthroplasty and did not have complications such as a need for inpatient care in recovery beyond an initial 5 days after surgery.

The researchers randomly assigned 165 knee arthroplasty patients with uncomplicated cases to undergo either inpatient rehabilitation for 10 days and then recover at home for 6 weeks or a monitored 6-week home rehab program that began 2 weeks after surgery (JAMA. 2017;317[10]:1037-46).

A third group of 112 patients, 87 of whom were included in the primary analysis, were observed as they entered the home rehab protocol. They were in an initial group of 215 who declined to be randomized, mostly because they wanted to get home quickly after surgery.

The average age of all participants was 67 years, and just over two-thirds were women.

At 26 weeks, the researchers found that there was no significant difference in how the patients in the three groups fared on a 6-minute walk test (mean difference, −1.01 meters; 95% confidence interval, −25.56 to 23.55). They also found no significant difference in measurements of patient-reported pain and function (knee score mean difference, 2.06; 95% CI, −0.59 to 4.71), and quality of life (EQ-5D visual analog scale mean difference, 1.41; 95% CI, −6.42 to 3.60).

However, the patients did seem to have a preference. “Satisfaction with rehabilitation was significantly higher with inpatient rehab, average 92% vs. 83%, though both modes were well received overall,” Dr. Naylor said in an interview.

“Many patients who went to inpatient rehabilitation really enjoyed it,” she added. “We have observed that patients and carers like the convenience of inpatient rehab – a one-stop shop where patients get access to multiple clinicians, gyms, and other patients and do not have to prepare meals.”

However, she said, while “we have no doubt the inpatient rehabilitation environment is nurturing, there must also be advantages to being discharged directly home, otherwise we would have seen differences between the groups. It is possible that monitored home programs like the one provided in this study help people gain independence quickly and empower patients in their recovery.”

Dr. Naylor cautioned that inpatient rehabilitation does have potential benefits for certain patients, such as those who are the most impaired and those without someone available to care for them at home. “Future research could focus on what is best in those situations or, at least, design community-based programs [that] offer some of the perceived benefits of inpatient therapy,” she said. “In addition, we also need to know what the best rehabilitation approach is after hip arthroplasty.”

The study was funded by various sources, including a foundation grant. The study authors reported no relevant disclosures.

Key clinical point: For patients with uncomplicated cases, brief inpatient rehabilitation after knee replacement surgery appears to provide no extra benefit, compared with at-home rehab.

Major finding: There were no significant differences in the primary outcome of a 6-minute walk test at 26 weeks or in pain, function, and quality of life measures between patients randomized to inpatient or at-home rehab protocols.

Data source: A parallel, randomized controlled trial of 165 uncomplicated knee arthroplasty patients assigned to undergo either inpatient rehab for 10 days then in-home monitored rehab for 6 weeks or to a monitored 6-week home rehab 2 weeks after surgery. The study also included a third observational group of 112 patients (87 included in analysis) who underwent at-home rehab.

Disclosures: The study was funded by various sources, including a foundation grant. The study authors reported no relevant disclosures.
