Table 3. The duration between hip arthroscopy and total hip replacement.

Time from hip arthroscopy to THR	Number
0–6 months	3
6–12 months	6
12–24 months	10
24–48 months	14
> 48 months	1

We also compared the incidence of THR in patients aged < 50 years (n = 60) compared with those aged ≥ 50 years (n = 17) but found no significant difference between the two groups (p = 0.79).
