TABLE 6.

Comparison of the Number of Patients With Each Grade of Atrophy for Labral-Level Tenotomy Patients (Current Study) and for Lesser Trochanteric Tenotomy Patients^{15 a}

		Grade of Atrophy					P Valueb
Site of Release	Patients	4	3	2	1	0	χ2	Fisher
Labral-Level	No.	2	2	6	15	3	<.012	<.013
Lesser-Trochanter15	No.	11	2	4	1	2

^aThe incidence of atrophy was similar (∼90%) in both groups, but there was a significant difference in the severity of atrophy which was significantly greater in the lesser trochanteric tenotomy patients as 11 (55%) of the lesser trochanteric tenotomy patients had grade 4 atrophy compared with 2 (7%) in the labral-level tenotomy group, and only 3 (15%) of the lesser trochanteric tenotomy patients had low (0-1) grade compared with 18 (64%) of the labral-level tenotomy patients.

^bComparisons of the total number of labral-level patients (n = 2) with the total number of lesser trochanteric patients with grade 4 atrophy (n = 11) and the total number of labral-level patients (n = 18) with the total number of lesser trochanteric patients with grade 0-1 atrophy (n = 3).
