Proprioception of the Knee Post MIS TKA and MIS-QS TKA

Not Applicable

Completed

• Conditions: Osteoarthritis
• Interventions: Procedure: total knee arthroplasty

• Registration Number: NCT02160977
• Lead Sponsor: Jia-kuo yu

Brief Summary

If the proprioception of the affected knee post total knee arthroplasty (TKA) can recover earlier, it will accelerate the regaining of motion control ability and motion control accuracy of the TKA patients. This study compared the proprioception difference of the post operation knees between the MIS-QS TKA group and the MIS TKA group.The differences of proprioception recovery were analyzed following the two different TKA procedures and the advantages of MIS-QS TKA in the recovery of knee. proprioception were discussed.

Detailed Description

Patients were scheduled prospectively to undergo total knee arthroplasties were randomly assigned to receive either a MIS-QS TKA or a MIS TKA. Proprioception of the knee position sense was assessed by the knee angle reproduction test (10\~20 degree, 30\~40 degree, 80\~90 degree of the knee flexion) prior operation, and 1 week, 6 weeks, 3 months and 6 months post operation. Paired two-tailed t tests with a level of significance of p \< 0.05 were used to assess the effect of the different arthroplasty procedure on the postoperative knee joint proprioception for all subjects.

Arm && Interventions

Group	Intervention	Description
QS-TKA	total knee arthroplasty	patients underwent minimally invasive surgery quadriceps sparing total knee arthroplasty (MIS-QS TKA)
MIS-TKA	total knee arthroplasty	patients underwent minimally invasive surgery total knee arthroplasty (MIS TKA)

Primary Outcome Measures

Name	Time	Method
Proprioception of the Knee Post Operation	six months	Proprioception of the knee position sense was assessed by the knee angle reproduction test (10\~20 degree, 30\~40 degree, 80\~90 degree of the knee flexion) prior operation, and 1 week, 6 weeks, 3 months and 6 months post operation.; Scale Name:degree scale range:0\~180 degree,and a higher values represent a worse outcome

Secondary Outcome Measures

Name	Time	Method
HSS(Hospital for Special Surgery) Score of the Knee Joint	6 months	Scale Name:score scale range:0\~100,and a higher values represent a better outcome
VAS(Visual Analogue Scale/Score) of the Knee Joint	6 months	Scale Name:score scale range:0\~100,and a higher values represent a worse outcome
