Table 2.

A comparison of HSS scores at each of the three followup periods

Clinical result (HSS score)	Minimum 6-year followup (N = 51)	Minimum 10-year followup (N = 49)	Minimum 15-year followup (N = 16)
85–100 points	40 (78%)	39 (80%)	11 (69%)
70–84 points	10 (20%)	6 (12%)	0 (0%)
60–69 points	1 (2%)	4 (8%)	1 (6%)
≤ 59 points	0 (0%)	0 (0%)	4 (25%)*

* Each patient with an HSS ≤ 59 score had additional medical comorbidities that contributed to poor functional scores (see Results); HSS = Hospital for Special Surgery.
