Knee Problems

Summary

Major advances in digital gait analysis

techniques now enable an objective

functional assessment to be carried

out before and after treatment.This

technique is equally of value in assessing

the results of injection therapies,

physical therapy and surgery. I have no

doubt it will prove extremely useful

in assessing treatment response in

patients with osteoarthritis. In the

elderly, improvements in gait either

by physiotherapy or other forms of

treatment can reduce the incidence

of falls.This provides an objective way

of assessing improvement, or indeed

deterioration.

The same technique is just as valuable

in the treatment of athletes. More

information is available on our website.

Knee Motion Analysis is available on request at London Gait Analysis based in St Olaf

House, London Bridge Hospital. For appointments and further details please call

or see

After consideration of the

available data, a single injection

of 6ml of a hyaluronan, a synovial

fluid supplement was given.This

was the only form of treatment

provided.

A month later the patient was

reviewed. At this stage, he had

complete relief of pain and

gait analysis was repeated. Not

surprisingly, right knee function

remains almost the same.

However, left knee flexion in the

swing phase had been restored

to normal at almost 60° and

more importantly, there had

been a substantial improvement

in the stance phase.The left knee

achieved an entirely normal 20°

of flexion during weight bearing.

This is important, as this flexion

during the stance phase of gait is

what provides the ‘spring’ in our

step. It’s what drives us forwards.

The normal timing of the gait

cycle had also been restored

with heel strike occurring about

midway through the gait cycle on

both sides.
