Hello,
As per my clinical experience, the weakness and
stiffness involving left knee after a
sprain do indicate underlying structural damage at various level with varying degree of involvement. There can be possible damage to:
* Medial or lateral collateral ligament
* Anterior or posterior cruciate ligament
* Medial or lateral meniscus
A detailed physical examination with ortho surgeon are needed to get complete clinical diagnosis to evaluate:
* Anterior and posterior drawer sign
* Medial and lateral meniscal signs
* Range of motion with degree
Support can be obtained with an
MRI of the knee for the final tissue diagnosis at microscopic level.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Bhagyesh V. Patel, General Surgeon
