[Isokinetic evaluation and gait study in patients undergoing arthroplasty of the knee: verification of the efficacy of rehabilitation]. / Valutazione isocinetica e studio del passo in pazienti sottoposti ad artroprotesi di ginocchio: verifica di efficacia riabilitativa.

In this work the Authors have studied the efficacy of a standardized rehabilitative trial in patients with knee arthroplasty using an isokinetic technique and walking evaluation. 20 patients affected by gonarthrosis were evaluated: each of them underwent on one side an isokinetic evaluation before and 60 days after surgery, and on the other side a step evaluation, at the begin of limb charging and 60 days after surgery. The isokinetic parameters (strength, work, power) showed a sharp decrease of absolute values as compared to the preoperative situation, while in the walking evaluation the time reduction still remains in the first impact of the foot.

Arthroscopic arthrolysis of intra-articular knee stiffness.

The authors report 15 cases of intra-articular knee stiffness treated by arthroscopic arthrolysis with or without section of the alar ligaments. The advantages to using this type of treatment as compared to mobilization in narcosis or arthrotomic arthrolysis are emphasized.
