Summary: Following ACL reconstructions, patients in a prospective cohort who underwent progressive pre- and postoperative rehabilitation showed superior patient-reported outcomes both preoperatively and 2 year postoperatively compared to patients in the Norwegian Knee Ligament Registry who received usual care.

Abstract:

Background

Recent studies highlight the importance of preoperative knee function for a successful postoperative outcome after ACL reconstruction (ACLR), yet little is known about the longer term outcomes of patients who undergo progressive preoperative and postoperative rehabilitation compared to usual care
Objectives: To compare preoperative and 2 year postoperative patient-reported outcomes in patients undergoing progressive preoperative and postoperative rehabilitation at a sports medicine clinic compared with usual care

Methods

We included patients aged 16-40 years undergoing primary unilateral ACLR. The preoperative and 2 year postoperative KOOS of 84 patients undergoing progressive pre- and postoperative rehabilitation at a sports medicine clinic (Norwegian Research Center for Active Rehabilitation [NAR] cohort) were compared with the scores of 2690 patients from the Norwegian Knee Ligament Registry (NKLR). The analyses were adjusted for sex, age, months from injury to surgery, and cartilage/meniscus injury at ACLR.

Results

The NAR cohort had significantly better preoperative KOOS in all subscales, with clinically relevant differences (>10 points) observed in KOOS Pain, ADL, Sports and Quality of Life. At 2 years, the NAR cohort still had significantly better KOOS with clinically relevant differences in KOOS Symptoms, Sports and Quality of Life. At 2 years, 85.7-94.0 % of the patients in the NAR cohort scored within the normative range of the different KOOS subscales, compared to 51.4-75.8 % of the patients in the NKLR cohort.

Conclusion

Patients in a prospective cohort who underwent progressive pre- and postoperative rehabilitation at a sports medicine clinic showed superior patient-reported outcomes both preoperatively and 2 year postoperatively compared to patients in the Norwegian Knee Ligament Registry who received usual care.
