摘要：Efficient reh abilitation of the quadriceps femoris mu scle in conv alescence is the cornerston e of full recovery following immobilization and sur gery of the knee.Wide variety of kin esi the rap eutic protocols have been describ ed and used in order to ensure the athlete's rapid re tu rn to spo rts.The aim of this stu dy was to investigate wh eth er pro tein supplem entation of the diet afte r arthro sco pic surger y of the kne e an d durin g app lication of a complete kin esi the rap eutic pro gram is beneficial for the pat ien t.A total of 56 patients,all competitive soccer play ers,were rec ruited for the study.Of these,47 had under gone arthro sco pic surgery for meniscal repa ir and nine for ACL rec onstructio n.They were randomized into two groups of 28 patients each - experimental (EG) and control (CG).Iden tical kin esi the rap eutic protocols were applied for both groups.All patie nts received the simila r standard diet;in addition to this diet,the EG pa tie nts received 1 g/ kg /d ay of high-quality milk and egg pro tein supplem ent (90.5 % protein content).Kinesiological evaluation of th e knee jo int condition was carried out by myotonometry (MTM) of the qua driceps muscle,thigh circumference (TC) measurem ent,ran ge of motion in the knee jo int,and manual muscle testing (MMT) at the injure d an d un injured side before and afte r the trial.Sta tistical analy sis was performed with the Stud en t's t-t est (data were presented as me an ± SD).At the end of the experiment,the injured leg TC was closer to the un injured leg TC in the EG patie nts (47.2 ± 2.1 vs 47.6 ± 2.6 cm,p>0.05) than th at in the con trols (46.7 ± 2.5 vs 48.4 ± 2.8 cm,p<0.05).Also,MTM during contraction of the quadriceps of the injured limb revealed closer values to those of the uninjured limb in the EG patients (113.1 ± 5.6 vs 114.6 ±4.1 units,p>0.05) than those of the control group patients (88.8 ± 7.7 vs 115.9 ± 4.4 units,p<0.001).The EG patients displayed better MMT scores at the end of trial than the CG patients (4.99 ± 0.05 vs.4.33 ± 0.26,p<0.001).The results of the study suggest that protein supplementation of the diet during kinesitherapy can bene∩cially contribute to the successful management of quadriceps hypotrophy after knee arthroscopic surgery of soccer players.
