PMID 41058126WHAT IT FOUND
Adding deep oscillation therapy to standard physiotherapy after ACL surgery significantly improved pain tolerance, reduced swelling, and increased knee movement compared to physiotherapy alone over 4 weeks.
Patients in the treatment group achieved full knee extension, while the control group retained a deficit. This supports DOT as an effective early adjunct.
Key findings
01Patients receiving deep oscillation therapy showed significantly higher pressure pain thresholds at 2 and 4 weeks compared to the control group.
02The treatment group achieved full knee extension (0° deficit) and significantly greater flexion (92.83°) at 4 weeks, whereas the control group had a persistent extension deficit and lower flexion.
03Knee circumference, a measure of swelling, decreased significantly more in the treatment group (to 37.62 cm) than in the control group (41.38 cm) at 4 weeks.

What it does not show
The study was conducted at a single centre with a relatively small sample size (60 participants). Blinding was not possible for participants or therapists due to the nature of the intervention, and outcome assessors were not blinded, which introduces a risk of performance and detection bias. The follow-up period was short (4 weeks), so it is unknown whether the benefits of DOT persist in the medium or long term. The study population was restricted to adults aged 25 to 40 years, so results may not generalize to younger or older patients.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not assume these benefits persist long-term or apply to all ACL patients. The study only followed patients for 4 weeks and used a specific surgical technique and age range, so the durability of the effect and its generalizability to other populations remain unproven.
