Abstract
In order to investigate the difficulty of quadriceps training in the presence of an effusion into the knee we examined 13 patients with chronic effusions by recording isometric muscle strength. Maximal strength was markedly lower in the presence of an effusion, and aspiration of the effusion produced a 13.6% increase in strength (p < 0.01). A further, small increase of 8% was recorded after intra-articular lignocaine injection. Isometric strength and surface integrated EMG correlated well in six patients.

This anatomical, mechanical study demonstrated that early atrophy of the vastus medialis prominence and loss of terminal extension after injury are indicative of general quadriceps weakness.

This review concentrates on inhibition of quadriceps activation and suggests some therapeutic implications, but does not deal with the reduced oxidative capacity and increased fatiguability of disused muscle since these have not been part of the programme of work.

It is suggested that stimuli from the knee joint reflexly inhibit the lower motoneurons supplying the quadriceps muscle, which may lead to the muscle weakness, the atrophy, and the deformity that are seen in association with joint disease.

It is concluded that postmeniscectomy inhibition is not simply due to perceived pain but is due, at least in part, to stimuli from the knee.

The study demonstrated remarkably different muscle activation levels between the exercises studied and clearly indicates that selection of the exercises needs to be based on the therapeutic objectives.

New areas for future laboratory and clinical research include articular receptor input in motor learning and relearning tasks as well as standardization of methodology and responses for assessing joint position.

A hypothesis was formed that suggests the decreased electrical activity at 0 degrees in the effused knees results from reflex inhibition caused by joint capsule distension and intra-articular pressures that change with joint position.

It is suggested that the known changes in the compliance of chronically effused joints are responsible for the observed differences in the effect of acute and chronic effusions.

Type 1 synovial rupture is the bursting of a distended joint capsule or communicating cyst or bursa allowing leakage of joint fluid directly into the surrounding tissue, and is thought to cause some instances of persistent periarticular edema.

There exists some limit to capsular distension in the posterior joint region beyond which fluid is diverted to other areas of the knee joint, according to recordings obtained from slowly adapting mechanoreceptors innervating the posterior aspect of the cat knee joint capsule.
