Actual JSW of Healthy Knees Across All Time Points (mm)a
| Male and Female, Mean ± SD | Male, Mean (Range) | Female, Mean (Range) | |
|---|---|---|---|
| Control group: left and right knees (n = 124) | |||
| Medial compartment | 3.6 ± 0.68 | 3.9 (2.2–5.2) | 3.4 (2.2–4.9) |
| Lateral compartment | 5.4 ± 0.68 | 5.6 (4.3–6.9) | 5.3 (3.7–7.4) |
| ACL group: uninjured knees (n = 77) | |||
| Medial compartment | 3.5 ± 0.62 | 3.8 (2.9–4.9) | 3.3 (2.3–5.1) |
| Lateral compartment | 5.3 ± 0.69 | 5.5 (4.3–7.0) | 5.1 (3.9–6.5) |
a
Joint space width (JSW) in control patients derived from each knee at baseline and follow-up. JSW in uninjured knees derived from the normal/healthy knee of patients in the anterior cruciate ligament (ACL) group at baseline and follow-up. JSW and range values of male and female patients derived from multilevel regression analysis.
