Pearson correlation analysis between tibial component coverage at 1 week after surgery and tibial bone resorption, patient-reported outcome measures (PROMS) (KSS total-post and WOMAC pain-post) at 2 years after surgery
Tibial component coverage (mm) | Tibial bone resorption (mm) | Patient-reported outcome measures | |||||||
---|---|---|---|---|---|---|---|---|---|
Mean ± SD (range) | Medial | Lateral | Anterior | p | KSS total-post | p | WOMAC pain-post | p | |
Medial | −0.98 ± 2.37 (−7.39 to5.29) | −0.30 | 0.001 | − 0.28 | 0.003 | 0.21 | 0.026 | ||
Lateral | −0.69 ± 2.00 (−5.44 to5.63) | −0.21 | 0.029 | 0.07 | 0.467 | −0.09 | 0.366 | ||
Anterior | −0.06 ± 1.63 (− 5.98 to3.62) | −0.17 | 0.076 | 0.08 | 0.403 | 0.00 | 0.983 |
Tibial component coverage, over-hang: positive value, under-hang: negative value; SD standard deviation; KSS score the Knee Society score; WOMAC score the Western Ontario and McMaster Universities Osteoarthritis Index score
