Intensive Muscular Strength Training Research On Lower Limbs Functional Recovery After TKA

Objective: Comparing the strength training group and traditional rehabilitationtreatment group12weeks after operation, its pain, PROM, muscle strength, HSSscore index changes, studying Intensive Muscular Strength Training on the functionof lower limbs after TKA surgery.Methods: From March2012to September2013,59cases patients undergoing primary TKA were included in joint surgery of hospitalof affiliated Qinghai University, one case was excluded because of the postoperativeinfection, effective cases have58cases. According to last number of their hospitalregistration. The single number and the double number is randomly divided into twogroups, the treatment group has32cases and control group has26cases.There was nosignificant difference in general information of two groups (P <0.05). Postoperative:the control group has given basic rehabilitation training, including general training,ROM training, weight training of lower limb body, active flexion and extension, etc.The treatment group has given basic rehabilitation methods and intensive muscularstrength training. Evaluation: Respectively evaluating knee pain, PROM, musclestrength, HSS scale of the two groups at1week,2weeks,4weeks,8weeks,12weeks after operation.Results:(1) PROM: knee flexion Angle of two groups atdifferent time contrast are increased gradually in postoperative12weeks (P <0.01), ithas no obvious difference between the two groups PROM at each time point (P>0.05);(2) VAS score: knee pain of two groups are gradually reducing in postoperative12weeks (P<0.01), there was no significant difference of two groups inpostoperative4weeks (P>0.05), the pain of experimental group relief more than thecontrol group after postoperative8week (P <0.05);(3) Strength: the strength oftwo groups was gradually increased in postoperative12weeks (P <0.01), the strengthof experimental group increased significantly better than the control group inpostoperative2weeks (P <0.05);(4) HSS: HSS score of knee joint of two groupswere gradually increased in postoperative12weeks (P <0.01), the score ofexperimental group significantly is better than the control group after postoperative4 weeks (P <0.01).Conclusion: After TKA, intensive muscular strength training canenhance the muscle strength and relief pain and improve the function of lower limbs,protect prosthesis joint, strengthen its stability, slow degeneration, enhance theirability of balance, avoid falling, and can reduce the incidence of complications suchas lower limber deep vein thrombosis. To prevent or delay the calcium loss andosteoporosis, and so on, is really an effective training after TKA surgery.
