Arthroscopic vs. Open Rotator Cuff Repair: No Significant Difference in Patient Outcomes or Cost-Effectiveness

For degenerative rotator cuff tears in patients over 50, both arthroscopic and open surgical repair yield comparable clinical outcomes and cost-effectiveness.

Key Findings

  • 01No statistically significant difference in the Oxford Shoulder Score (OSS) at 24 months between arthroscopic and open repair groups.
  • 02The difference in OSS between the groups did not meet the predetermined clinically important difference of 3 points.
  • 03No statistical difference was observed when comparing groups on a per-protocol basis.
  • 04High questionnaire response rates (>86%) indicate robust data collection.

Application

Design takeaway

When designing or evaluating surgical interventions for rotator cuff repair, focus on demonstrating clear advantages in patient outcomes, recovery time, or cost-effectiveness, as current evidence suggests comparable results between arthroscopic and open methods for degenerative tears.

How to apply

When developing new surgical tools or techniques for rotator cuff repair, benchmark against existing arthroscopic and open procedures for comparable patient outcomes and economic viability. Consider the potential for surgeon preference to influence adoption.

Project actions

  • 01When comparing different design solutions, ensure you are measuring outcomes that are clinically relevant and meaningful to the end-user.
  • 02Consider both the direct performance of the product and its broader economic impact.
  • 03Acknowledge that established practices may not always be superior and that innovation should be rigorously tested against them.

Method & Evidence

AimTo compare the clinical effectiveness and cost-effectiveness of arthroscopic versus open surgical repair for degenerative rotator cuff tears in patients aged 50 years and older.
MethodRandomised controlled trial (RCT)
ProcedurePatients with degenerative rotator cuff tears were randomly assigned to either arthroscopic or open surgical repair. Outcomes were assessed using the Oxford Shoulder Score (OSS) at 24 months, with additional assessments of repair integrity via MRI at 12 months. Follow-up included questionnaires at various intervals.
Sample273 participants
ContextOrthopaedic surgery, specifically rotator cuff repair.

Strengths & Limitations

Strengths

  • +Randomised controlled trial design provides a high level of evidence.
  • +Large sample size for a surgical trial.
  • +Inclusion of cost-effectiveness alongside clinical effectiveness.
  • +High questionnaire response rate ensures data reliability.

Limitations

The study's findings are specific to degenerative rotator cuff tears in patients over 50. The results might differ for acute tears or different patient demographics. The 'usual and preferred method' used by surgeons introduces variability.

Reliability & validity

The study's reliability is supported by the RCT design and high response rates. Validity is enhanced by using established outcome measures like the OSS and MRI, though the 'usual and preferred method' by surgeons could introduce some variability in technique, potentially affecting internal validity if not controlled for.

Think critically

Given the comparable outcomes, what factors beyond clinical effectiveness (e.g., surgeon training, patient preference, specific tear characteristics, long-term complication rates) should influence the choice between arthroscopic and open rotator cuff repair?

05

Design Principles

"Clinical effectiveness and cost-effectiveness should be primary drivers in the adoption and development of surgical techniques and associated technologies."

This finding is crucial for healthcare providers and surgical device manufacturers when making decisions about resource allocation and product development. It suggests that the choice of surgical approach may not significantly impact patient recovery or long-term satisfaction, potentially influencing surgical training, equipment investment, and reimbursement policies.

06

What This Means for Your Design

For older adults with torn rotator cuffs, fixing them with keyhole surgery (arthroscopic) or with a bigger cut (open surgery) works about the same for how well your shoulder feels and works afterwards. It also doesn't seem to make a big difference in cost.

How to use in your project

  • 1.Reference this study when discussing the comparative effectiveness of different design approaches in medical devices or surgical procedures.
  • 2.Use the findings to justify the selection of a particular design pathway based on evidence of comparable outcomes and cost-effectiveness.

Paragraph starter

Research by Carr et al. (2015) in the Health Technology Assessment journal demonstrated that for degenerative rotator cuff tears in patients aged 50 and over, both arthroscopic and open surgical repair techniques resulted in statistically similar clinical outcomes, as measured by the Oxford Shoulder Score at 24 months. This suggests that from a patient outcome perspective, the choice between these two surgical modalities does not yield a significant difference, impacting considerations for resource allocation and technology adoption in orthopaedic practice.
