Difference of Knee Strength Recovery Between Revision and Primary ACL Reconstruction.

Different grafting procedures are available to restore knee stability after revision anterior cruciate ligament (ACL) reconstruction. We compared knee strength recovery between ACL revision surgery and primary reconstruction. One hundred and ten patients with ACL revision surgery were matched with 110 patients with primary reconstruction based on the graft procedure. The isokinetic knee strength had been assessed for the first 9 months post-surgery. Knee laxity, function, and activity score were also evaluated. Limb symmetry index for knee extensor and flexor strength was not different at 4-, 6- and 9-months post-surgery between revision surgery and primary reconstruction. These results depended on ipsilateral or contralateral graft choice. Ipsilateral hamstring tendon (HT) and contralateral bone-patellar-tendon-bone (BPTB) graft procedures were similar for a revision of a BPTB graft failure. Contralateral HT procedure was better than ipsilateral BPTB procedure for a revision of a HT graft failure. The early recovery of isokinetic knee strength after ACL revision surgery regardless of the HT or BPTB procedures, was similar to the recovery after primary ACL reconstruction with the same graft technique. These results apparently depended on a temporary quadriceps arthrogenic muscle inhibition and on a persistent donor site morbidity, concerning the new and the previous grafts, respectively.

A score for measurement of the role of social vulnerability in decisions on abortion.

OBJECTIVE: To devise a score allowing a better measure of the role of social vulnerability (SV) in a woman's attitude toward abortion. STUDY DESIGN: Consecutive sampling and semi-structured personal interviewing of 2641 women requesting legal termination of pregnancy from 1994 to 2001 in the county of Roanne, France. RESULTS: SV was estimated from each woman's situation with reference to work, family composition, marital status, health insurance status and characteristics of neighbourhood of residence. It was correlated with the income and home ownership situation. With a high SV level taken as reference, the relative risks (RR) of severe, moderate, and low SVP, respectively, were equal to 3.3 (1.8-6.1), 4.6 (2.5-8.6) and 7.2 (3.9-13.1) in women under 18.5 years of age; 1.2 (1.0-1.5), 2 (1.4-2.8), and 2.1 (1.4-3.2) from 18.5 to 19 years of age; 0.7 (0.6-0.8), 0.6 (0.5-0.8) and 0.4 (0.3-0.5) in those aged 19-28; and 0.9 (0.9-1), 0.7 (0.6-0.8) and 0.71 (0.6-0.8) in those over 28. The use of different basic hypotheses (cumulative time of pregnancy in women's life, withdrawal or restarting of the clock after each event in the case of recurrence) resulted in slight modification of the age cut-off points and the amplitude of RR also differed, but their order relative to SV categories was unchanged. CONCLUSIONS: At the individual level knowledge of SV allowed a good estimate of a woman's attitude to an unwanted pregnancy, and SV must be taken into consideration when future actions are planned.
