Abstract

Background: In Pakistan, total knee replacement (TKR) is a common surgical intervention for end-stage knee osteoarthritis. Effective post-operative rehabilitation is essential for optimal outcomes, with pain management being a critical component. This cross-sectional study examines the integration of objective pain assessment technologies in outpatient rehabilitation settings and analyzes their relationship with clinical outcomes and treatment customization.

Methods: This cross-sectional survey was conducted across three campuses of Dr. Ziauddin Hospital from August 2023 to March 2024. Data was collected from 245 post-TKR patients and 78 healthcare providers. Assessment included documentation of pain evaluation methods, rehabilitation protocols, clinical outcomes, and technology adoption factors. Statistical analysis examined associations between assessment methodologies and patient outcomes.

Results: Among surveyed centres, 42.3% utilized at least one objective pain assessment technology, with significant regional variation. The most commonly employed technologies were digital pressure algometry (24.6%), simple mechanical goniometry (18.7%), and digital visual analogue scales (16.5%). Centres employing objective assessment tools reported significantly better pain management scores (mean difference 1.7, p<0.01) and higher patient satisfaction (73.8% vs. 58.4%, p<0.01). Treatment customization based on objective measurements was associated with improved functional outcomes measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).

Conclusion: Integrating objective pain assessment technologies in post-TKR rehabilitation is associated with improved clinical outcomes and personalized treatment approaches. However, significant barriers include cost constraints, technical expertise limitations, and infrastructure challenges. Strategies to address these barriers could significantly enhance rehabilitation quality and patient outcomes across Pakistan’s diverse healthcare setting.
