“…For the hamstring muscle, a low deficit of strength and no significant difference in performance between the two groups were verified in any test conditions. This finding agrees with several studies [17,18,20] which reported that hamstring muscles are less affected by immobilization than quadriceps femoris muscles. Because three of the four hamstring muscles are biarthrodial crossing the hip and the knee joints, the major activity of these muscles can be maintained when motion at one of the two joints is limited [17].…”

The purpose of this study was to compare the effects of two protocols of electrical stimulation combined with voluntary contractions on the recovery of thigh muscles after anterior cruciate ligament (ACL) surgery. Ten sportsmen with a mean age of 26 yrs were randomly assigned into two groups: a 80 Hz stimulated group (5 patients) and a 20 Hz stimulated group (5 patients). All patients received electrical stimulation of the quadriceps femoris, five days a week, for 12 weeks, and had a standard program of voluntary contractions. Muscle and fat volumes of the thigh were assessed using MRI before surgery and after 12 weeks of rehabilitation. Quadriceps and hamstring muscle strength were evaluated by isokinetic measurements. Twelve weeks after surgery, the quadriceps peak torque deficit in the operated limb with respect to the non operated limb at 180 degrees /s and 240 degrees /s was significantly (p < 0.05) less in the 20 Hz group than in the 80 Hz group. This difference was not confirmed when comparing the pre-surgery quadriceps peak torque of the operated limb with the post-surgery one. Subcutaneous fat volume was increased for the two groups at the post-surgery test. This increase was significantly (p < 0.05) greater for the 80 Hz group. Thigh muscle volume deficit was not significantly different between the two groups.

“…In contrast to the quadriceps, the hamstrings are less susceptible to strength deficits following an ACL injury. These deficits are thought to be due to bi-arthrodial nature of three of the four hamstring components such that even when knee mobility is impaired following in ACL injury, hip extension continues to act as stimulus for the hamstrings [19-22]. Also the current rehabilitation protocols emphasis early and aggressive hamstring training following an ACL reconstruction [23-26] on the basis that hamstring contraction can produce posterior tibial translation to reduce the strain on the maturing ACL substitute [19].…”

BackgroundHaemarthrosis and pain adversely affects the functional outcome of ACL reconstruction, especially in case of DB ACL reconstruction due to more extensive procedure. The purpose of the study was to evaluate the effect of haemarthrosis on the rehabilitation of DB ACL reconstruction versus SB ACL reconstruction.Methods100 patients were divided into two groups, of SB ACL and DB ACL reconstruction consisting of 50 patients each. An intra-articular drain was put in every patient. The pain was evaluated till week 8 using VAS (Visual Analog Scale). The Functional outcomes were evaluated using the Isokinetic Dynamometer at 3 and 6 months in both the groups. Muscle bulk and Range of motion were also noted in each group.ResultsThe results showed that there was statistically significant difference between the drain amount (n = 60.3 ml in SB ACL group vs. n = 94.2 ml in the DB ACL group) and haemarthrosis (n = 0.7 in SB ACL vs n = 1.5 in DB ACL) at week 1 post-operatively. Also the pain outcome improved on SB ACL after day 3 (VAS, n = 1.8) as compared to the DB ACL group (VAS, n = 3.7). The isokinetic muscle strength was found to be statistically significantly (p value < 0.05) better in the SB ACL group in the quadriceps muscle (both concentric and eccentric) at the end of the 3rd month. In the SB ACL group the Quadriceps Concentric strength deficit was 22.32% as compared to 34.12% in the DB ACL group. Both the groups had comparable flexor muscle strength at end of 3rd month. Both the groups had comparable muscle strength after 6 months of post-operative rehabilitation in both quadriceps and Hamstring muscle group.ConclusionWe noted that rehabilitation of DB ACL reconstruction group lags behind that of SB ACL reconstruction during the first 3 months due to post-operative haemarthrosis & its effects, but show comparable results after 6 months. The muscle strength measured isokinetically and the muscle bulk were found to be greater in the SB ACL group initially after 3 months but was found to be similar after 6 months.

“…This latter finding, coupled with the similarity in hamstring muscle area, is consistent with recently published data. 28 The clinical isokinetic data indicated that quadriceps torque in the operative leg was still insufficient even after 1+ year of rehabilitation. This is consistent with other reported data.…”
