Abstract

Purpose

Although pain is often the chief complaint to address with conservative treatments in knee osteoarthritis (OA) patients, little is known about pain location patterns and evolution. Biomechanical knee dysfunctions are known to increase mechanical stress on specific joint compartments (e.g., medial side for patients with varus thrust) and to be correlated with patient symptoms. This study explored the impact of a personalized care approach targeting biomechanical dysfunctions (i.e., markers) and the chief pain location in knee OA patients.

Methods and Materials

We analyzed a sub-group of 97 patients from a cluster randomized controlled trial with confirmed radiographic OA (Kellgren-Lawrence, KL2-KL3-KL4). A self-administered Photographic Knee Pain Map (PKPM) was completed at baseline and 6-month follow-up. The zone (medial, anterior, lateral, posterior) with the most crosses at baseline was considered the chief pain location (Figure 1). A knee kinesiography exam assessing biomechanical markers was performed and conservative recommendations including tailored exercises targeting the identified chief pain location and markers were suggested. Pain intensity was monitored using the Knee Injury and Osteoarthritis Outcome Score (KOOS).

Results

Globally, 39 (40.2%) patients showed pain suppression in their chief pain location after 6 months, and participants improved their KOOS-pain score by 15.5% (no between-KL grades difference, both p≥0.308, Table 1). More than half of the KL2 group showed pain suppression in their chief pain location (51.9%). Proportion of patients who showed complete pain suppression (no cross in any zone on the 6-month PKPM) was significantly higher for KL2 than KL4 grades (18.5% vs 0%; p=0.023).

Conclusion

Personalized care approach allowed pain suppression in patients’ chief pain location regardless of the radiographic severity. Patients with lower KL grade were more likely to get rid of their knee pain. Results support that such personalized approach targeting biomechanical markers and chief pain location allows to address knee pain levels, especially in early OA stage.
