BACKGROUND: Elbow tendinopathies are associated with tenderness, pain, and functional disability with ensuing socioeconomic costs. There is lack of consensus regarding the best treatment for patients recalcitrant to first-line conservative treatments. Percutaneous needle tenotomy is considered a regenerative approach that injures the tendon to elicit a healing response.
OBJECTIVE: To investigate whether demographic characteristics, clinical factors, baseline sonographic entities, or their interactions are related to the likelihood of responding positively to needle tenotomy over a 1-year follow-up period.
DESIGN: Prospective case series.
SETTING: Tertiary institutional hospital.
PARTICIPANTS: Patients with elbow tendinopathy for whom conservative treatments had failed and who had persistent symptoms lasting for at least 3 months.
METHODS: Patients underwent needle tenotomy with or without PRP followed by a lighter needle tenotomy within a 2-week interval as part of treatment.
MAIN OUTCOME MEASUREMENTS: Disabilities of the Arm, Shoulder and Hand (DASH) and Visual Analogue Scale for pain (VAS-P) scores were assessed before intervention (baseline) and at 6 weeks and 3, 6, and 12 months after intervention. A generalized linear mixed effects model was created to examine whether injectate type, clinical, demographic, or pretreatment sonographic entities or their interactions influenced clinical outcomes.
RESULTS: The authors analyzed 74 elbows (71 patients). At baseline, analyzed patients (mean age: 49.48 years; 51.35% women) scored 43.30 and 5.83 on the DASH and VAS-P, respectively. Pretreatment tendon vascularization was a predictor of pain (P = .011) and DASH score changes (P = .019). The linear mixed effect model revealed that male gender and hypercholesterolemia were associated with enhanced functional recovery, (P = .020 and P < .001, respectively). Moreover, the interactions between pretreatment vascular status (P = .039), echotexture (P = .037) and enthesophytes (P = .028) influenced the temporal pattern of functional recovery after needle tenotomy.
CONCLUSIONS: Baseline patient characteristics, such as gender and hypercholesterolemia, along with ultrasound features may be predictive of outcomes following needle tenotomy for elbow tendinopathy.
LEVEL OF EVIDENCE: IV (NCT01945528).
