My husband worked for the usps get got injured on the job damaged his knee he waited 5 months before surgery his knee got damaged more a lot of delays

I am sorry to hear about your husband's injury and hope that he recovers fully. More facts are needed which can be discussed in consultation. An experienced professional can guide and advise you and evaluate his claim.  You will have to reach out, as attorneys are unable to directly solicit on this forum. Do not delay so as not to prejudice his rights.
