Table 2. Stifle radiographic parameters before and after injection with bone marrow-derived mesenchymal stem cells.

Radiographic parameter	Partial CR stifle		Complete CR stifle
	Diagnosis	8 weeks	Diagnosis	8 weeks
Synovial effusion severity score	1.5 (1, 2)	2 (1, 2)	2 (2, 2)a	2 (1, 2)
Osteophytosis severity score	1 (1, 3)	1 (1, 3)	2 (1, 3)b	2 (2, 3)
CrCLd (mm)	33.5±2.9	32.1±3.3	38.9±2.9c	33.7±2.4d

Note: Instability in the complete CR stifle was treated with tibial plateau leveling osteotomy at diagnosis. CrCL_d represents the functional length of the ligament under load as determined by weight-bearing radiography [28].

^aP<0.05

^bP<0.01

^cP<0.005 versus contralateral stifle.

^dP = 0.06 versus complete CR stifle at diagnosis. Abbreviations: CR, cruciate ligament rupture; CrCL, cranial cruciate ligament.
