Tibial component coverage affects tibial bone resorption and patient-reported outcome measures for patients following total knee arthroplasty

Table 3 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

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
