# Manual Therapy in Post-operative Knee Management: A Systematic Review of Effects on Pain in Total Knee Replacement (TKR) Patients

## TL;DR

This review examines if manual therapy helps reduce pain and improve recovery after total knee replacement surgery.

## Contribution

The study systematically reviews randomized trials to clarify manual therapy's role in post-TKR pain management.

## Key findings

- Manual therapy reduced pain and improved joint mobility in early postoperative recovery.
- MLD and KT showed short-term benefits in pain relief and swelling reduction.
- Results varied due to differences in treatment timing and patient populations.

## Abstract

Manual therapy is a hands-on treatment approach commonly used by healthcare professionals, such as doctors of osteopathic medicine, physical therapists, chiropractors, and massage therapists, to address musculoskeletal pain and improve functional recovery. Although its effectiveness is well established for various musculoskeletal conditions, its role in postoperative knee rehabilitation, particularly after total knee replacement (TKR), remains underexplored. Postoperative pain following TKR can significantly affect mobility and delay recovery, underscoring the need for effective rehabilitation strategies. While individual studies have reported mixed outcomes of manual therapy after TKR, the evidence base is fragmented and lacks consensus. A systematic review is therefore warranted to synthesize current findings, evaluate the quality of available evidence, and clarify whether manual therapy provides meaningful benefits in pain reduction, functional outcomes, or patient satisfaction after TKR.

The primary objective of this study was to review existing randomized controlled trials (RCTs) to evaluate the impact of manual therapy on pain management in patients following TKR surgery. The study aimed to synthesize current evidence regarding the effectiveness of different manual therapy techniques in reducing postoperative pain and enhancing functional outcomes.

A comprehensive literature search was conducted using multiple databases, including PubMed, CINAHL, Cochrane, and Ovid Medline. The initial search yielded 332 articles, which were screened against predefined inclusion and exclusion criteria. After screening, 10 RCTs focusing on manual therapy as the primary intervention in postoperative knee patients were selected for detailed review. The interventions studied included osteopathic manipulative treatment, manual lymphatic drainage (MLD), Kinesio Taping (KT), and multimodal manual therapy techniques. Data regarding pain outcomes, treatment protocols, and follow-up durations were extracted and analyzed.

The reviewed studies suggest that manual therapy can effectively reduce pain, improve joint mobility, and decrease the use of pain medications during the early postoperative period. MLD and KT showed particular promise in providing short-term pain relief and reducing swelling when applied soon after surgery. Some studies also reported improved patient satisfaction and faster functional recovery with manual therapy. However, findings were inconsistent across studies due to differences in treatment timing, methodologies, and patient populations. Long-term benefits of manual therapy remain unclear, emphasizing the need for further research.

Manual therapy appears to be a viable complementary treatment option for managing pain and improving functional recovery after TKR surgery. Its hands-on nature, lack of specialized equipment requirements, and adaptability to individual patient needs make it an attractive rehabilitation approach. Despite encouraging preliminary evidence, more rigorous research, with larger sample sizes and standardized protocols, is necessary to definitively establish the effectiveness of manual therapy and to guide clinical practice.
