OPINION OF THE COURT
In this appeal, K-Mart challenges first, the propriety of a preliminary injunction which enjoined it from denying coverage for plaintiff’s high-dose chemotherapy with autologous bone marrow transplant procedure, and second, the amount of the injunction bond. Because both issues are moot, we will dismiss the appeal.
I.
Susan Clark- was diagnosed as having metastatic breast cancer. Her oncologist, Dr. Jeffrey E. Shogan, recommended that she receive high dose chemotherapy with autologous bone marrow transplant (“HDCT-ABMT”). Compared to conventional therapies, this procedure offered Mrs. Clark a relatively good probability of remission and even a reasonable possibility of long-term survival. But it had to begin almost immediately and was estimated to cost in the neighborhood of $150,000.
Mrs. Clark is an employee of K-Mart and sought coverage for this procedure under K-Mart’s self-insured Comprehensive Health Care Plan. 1 K-Mart has the final authority to determine whether a claim is covered under this ERISA plan, but has contracted with Blue Cross and Blue Shield of Michigan to manage the daily operations of the Plan. Blue Cross concluded that the treatment was experimental and investiga-tional, not covered by the Plan, and K-Mart denied coverage.
Mrs. Clark filed this ERISA action seeking a preliminary injunction to compel K-Mart to fund her HDCT-ABMT treatment. After a hearing, the district court granted her motion and enjoined K-Mart from denying coverage for the procedure, conditioned, however, upon payment of a $1,000 bond. The injunction issued on September 13, 1991. K-Mart did not seek a stay of the preliminary injunction. Rather, it appealed both the propriety of the injunction and the amount of the bond.
II.
At both the panel and in banc arguments, it came to the court’s attention that K-Mart had complied with the preliminary injunction. K-Mart never disputed this at either argument. Following argument before the court in banc, we asked the parties to address whether this appeal was moot in light of
University of Texas v. Camenisch,
If counsel for K-Mart wished to argue that we should consider only facts in the district court record, he should have forthrightly responded to our request and then argued that, notwithstanding the additional facts, the new facts were not properly before us and should not be considered. Counsel knew or could have found out whether Mrs. Clark received the treatment, *967 and whether K-Mart paid for it. Hence, we will deem admitted Mrs. Clark’s unre-butted statement that she received the treatment and that K-Mart paid for it.
Finally, there is nothing in the record to indicate that Mrs. Clark could ever receive the HDCT-ABMT treatment again. Indeed, it was unrebutted at oral argument before the panel that once the treatment is administered, it will not be given again. 2

We are normally limited in our review to those facts developed in the district court.

At one time, the possibility of recovering on an injunction bond would save an appeal from mootness. In the context of a preliminary injunction, a panel of this court once held that the issue of recovery on the bond kept the appeal of the injunction from becoming moot.
Washington Steel Corp. v. TW Corp.,
Two years later, however, the Supreme Court rejected the reasoning of Washington Steel in University of Texas v. Camenisch. 4 Camenisch, who is deaf, sued his university under the Rehabilitation, Act of 1973 requesting that it be ordered to pay for a sign-language interpreter. The district court granted a preliminary injunction, conditioned on payment of a $3,000 bond, and the university appealed. While the appeal was pending, however, the university paid for the interpreter and Mr. Camen-iseh graduated. Nevertheless, the Fifth Circuit Court of Appeals held that the issue of who should ultimately bear the cost of the interpreter, in other words the merits action, saved the appeal from mootness.
The Supreme Court disagreed. Although acknowledging that the
case
was not moot, it held that the
issue
on appeal, whether the
preliminary
injunction was properly entered, was both separate from the bond and moot.
[Wjhere a federal district court has granted a preliminary injunction, the parties generally will have had the benefit neither of a full opportunity to present their cases nor of a final judicial decision based on the actual merits of the controversy. Thus when the injunctive aspects of a case become moot on appeal of a preliminary injunction, 5 any issue preserved by an injunction bond can generally not be resolved on appeal, but must be resolved in a trial on the merits.
The two issues — whether the district court erred by entering a preliminary injunction, and which party is ultimately liable for the costs incurred by complying with that injunction — are significantly different.
because it improperly equates “likelihood of success” with “success,” and what is more important, because it ignores the significant procedural differences between preliminary and permanent injunctions.... [A] preliminary injunction is customarily granted on the basis of procedures that are less formal and evidence that is less complete than in a trial on the merits.
The rationale of Camenisch applies here. The district court, faced with the exigencies of a life-threatening illness and a treatment that had to begin almost immediately, did not have the luxury of conducting anything resembling a trial on the merits. Rather, its hearing was limited to a few hours of testimony from Mrs. Clark’s treating physician and Blue Cross’ in-house expert to simply decide whether it was likely that Mrs. Clark could succeed in a full merit hearing in showing that the plan administrator acted arbitrarily and capriciously. After hearing this limited testimony, the district court granted the preliminary injunction from the bench.
For this reason especially, it is appropriate that the issue of whether K-Mart acted arbitrarily and capriciously, which in turn will determine who is liable for the costs of Mrs. Clark’s treatment, be determined only after a full hearing by the district court. It may well be that the district court will find that K-Mart did not act in an arbitrary and capricious fashion by denying coverage to Mrs. Clark. It is not for us, however, to make that decision on this limited record. There may be many reasons of which we are not now aware to guide the final judgment of the district court. For example, there may be other and overwhelming evidence that Blue Cross capriciously ignored, making its decision on incomplete evidence arbitrary..

In addition, there is nothing to be gained by deciding this issue now. It is settled that one can recover on an injunction bond only after a trial and final judgment on the merits.

We also conclude that this case does not avoid mootness by fitting into that category of cases “capable of repetition, yet evading review.”
See, e.g., Brody v. Spang,
III.
Fed.R.Civ.P. 65(c) obligated the district court to require a bond as security for payment of damages and costs by K-Mart in the event the district court decides after trial that the preliminary injunction was wrongfully issued. The district court was aware of the costs of the procedure, but nevertheless fixed the bond at $1,000. K-Mart appeals, contending that the amount of the bond is inadequate. This issue is also moot.
The district court in its oral opinion made the injunction effective only if Mrs. Clark posted the bond. It did not compel her to post the bond. If Mrs. Clark was unwilling to take the risk inherent- in posting a bond dr was unable to obtain a bond, the district court would not have issued an injunction or, if it had already done so, could have vacated it. Whether the bond is adequate or not, if we reverse the district court- and increase the amount of the bond, Mrs. Clark will not be compelled to post it since K-Mart has already complied with the preliminary injunction.
We likewise will not hold that a party who accepts the benefit of a preliminary injunction by posting a nominal bond implicitly agrees to post a larger bond if unsuccessful on appeal, because that would eliminate the choice the district court gave the party of whether or not to accept the condition and post the bond.
Finally, we conclude that the issue is not saved from mootness on a theory that were we to conclude the $1,000 bond is inadequate, Mrs. Clark may
choose
to post a larger one. The parties cannot now remake their decision, and we cannot place Mrs. Clark back into the legal and factual position she .was in when she made the original choice to post the $1,000 bond. Thus, the appeal with respect to the bond is moot.
Cf. Murray v. Silberstein,
IV.
We hold that K-Mart’s appeal contesting the propriety of this preliminary injunction and the amount of the injunction bond is moot because K-Mart has complied and Mrs. Clark will not receive the treatment again. Because both issues raised on appeal are moot, we will dismiss this appeal and remand to the district court for a hearing on the merits.
Notes
. The hospital where the procedure was to be given required that Mrs. Clark be determined eligible for coverage before the treatment began.
. We are not persuaded by K-Mart's argument that the record supports the possibility of re-treatment. The most the record shows is that other treatment protocols- administer two HDCT-ABMT treatments, within a few weeks or months of each other, in an effort to increase the effectiveness of the therapy. Here, Mrs. Clark received the treatment once, over a year ago, and has not received it again. There is no record evidence whatsoever that Mrs. Clark could seek re-treatment.
. In Brody, we did remand, but for reasons other than to determine mootness.
. The Supreme Court never cited Washington Steel in its opinion. However, to the extent Washington Steel is inconsistent with this opinion, we now overrule it.
. Because an appeals court would have a full trial record following a permanent injunction, the Court left undisturbed, the rule that an injunction bond preserves such an appeal from mootness. Id.
. To illustrate its point, the Supreme Court used two of our earlier cases.
